Microwaves, Medicine and Mobility - IMS2018 Wrap Up
But the main theme was 5G
While the theme of IMS2018 was Microwaves, Medicine and Mobility, the real theme was 5G, 5G and 5G. Most companies in the exhibition were highlighting their play in the 5G market and with the one day 5G Summit, there were many talks addressing 5G applications and technologies. At the end of the day on Monday, June 11th, the IMS2018 plenary session kicked off with some background on this year’s event, with specifics on the conference and exhibition provided by Afshin Daryoush, Symposium Co-Chair, Sridhar Kanamaluru, Symposium General Chair, and Mohammed Tofighi and Al Katz, Symposium Technical Program Chairs.
This year’s event included 4 conferences, 600+ exhibitors, 75 technical sessions, and about 840 presentations over 6 days. More than 885 papers were submitted and 425 were accepted, making a 48% acceptance rate. Of the 47 workshops submitted, 33 were accepted. There were papers from 45 countries, with 70% from outside the USA. This year’s IMS included two new events, a panel of physicians and the IMBioC opening session that was held jointly with the IMS closing session.
The plenary session also took the time to pay a moment of tribute and silence for Tom Brazil, the 2018 MTT-S President who passed away suddenly in April 2018. Then, the attendees were introduced to the first female president of MTT-S, Dr. Dominique Schreurs of the University of Leuven (KU Leuven), Belgium. Schreurs noted that female membership of MTT-S is 5.5%, and she wants to improve that number as well as encourage participation of young professionals during her term. Next, Wolfgang Heinrich, 2018 EuMA President, talked about the close relationship between MTT-S and EuMA (European Microwave Association). He noted that the groups benefit from scientific exchange across borders, and said that “transnational co-operation is a key asset for our community.” The MTT-S EuMA partnership is well established, and EuMA is hosting European Microwave Week in Madrid, Spain the 23rd-28th of September 2018; he encouraged audience members to attend (registration is now open).
The plenary keynote took an interesting journey through the new technologies enabling the delivery of health care. In his talk, Steve Klasko, MD, MBA, and President & CEO of Thomas Jefferson University and Jefferson Health, noted that today’s up and coming healthcare consumers want to access their health care and health history the same way they do banking—which is not at the brick and mortar bank. Klasko shared some of the innovations being done at his facility, generally noting that tele-health leads to increased patient satisfaction. For example, with virtual rounds, doctors and patients can communicate with family members who are not in the building during doctor visits in the hospital room.
Microwave Journal visited as many companies as possible in the exhibition. Here is a summary of the ones we saw (see our photo gallery here):

The kit includes a gage with digital readout, for precision measurements.
W. L. Gore & Associates featured several 5G and aerospace & defense testing insights. Gore introduced GORE® PHASEFLEX® Microwave/RF Test Assemblies, Type 0N – the smallest, lightest, most internally ruggedized assembly on the market today for modular, multi-port, and multi-site test applications to address 5G applications. In the area of defense and aerospace, Gore featured its GORE® PHASEFLEX® Microwave/RF Test Assemblies and their airframe assemblies, GORE-FLIGHTTM Microwave Assemblies, 6 Series. The airframe assemblies are lightweight cable solutions that deliver the lowest insertion loss before and after installation, ensuring reliable performance for the life of an aircraft system. The robust construction reduces total costs by withstanding the challenges of installation, reducing costly production delays, field service frequency, and the need for purchasing replacement assemblies.
Analog Devices expanded its RadioVerse™ technology and design ecosystem with the widest bandwidth RF transceiver (200 MHz that provides designers with a single radio platform for the deployment of 5G, sustaining 2G/3G/4G coverage, and simplifying phased array radar design. The ADRV9009 RF transceiver delivers twice the bandwidth of previous generation devices and replaces as many as 20 components, cutting power in half and package size by 60 percent. The device is tunable over a range of 75 MHz to 6 GHz to support 2G/3G/4G/5G services, which allows cellular equipment manufacturers to adopt a single, compact radio design across all band and power variants.
Just prior to the event, ADI announced a new synthesizer consisting of a PLL with fully integrated VCO as well as integrated low dropout regulators and integrated tracking filter technology. The ADF4371 is the highest frequency synthesizer and offers the widest continuous RF output range of 62 MHz to 32 GHz. It has a low PLL FOM (-234 dBc/Hz), low spurious (-100 dBc typ.), low VCO phase noise (-134 dBc/Hz @ 1 MHz offset at 8 GHz), and built-in tracking filter technology. The ADF4371 supports RF/microwave system designs across multiple markets, including aerospace and defense, test/measurement, communications infrastructure, as well as high-speed converter clocking.
Ampleon, formerly NXP’s RF power business that was sold when NXP acquired Freescale, offers LDMOS and GaN products for wireless infrastructure, RF energy, aerospace and defense and broadcast applications.
Preparing for the rollout of 5G, Ampleon is developing power amplifiers for the sub-6 GHz 5G bands, with both LDMOS and GaN devices — in some cases identical products in each technology, allowing the customer to trade performance and price. Consider, for example, a three-stage, 3.5 GHz Doherty amplifier developed for 5G massive MIMO base stations in China. The GaN amplifier provides 43 percent power-added efficiency, compared to 40 percent for the Gen 10 LDMOS version; the GaN version is currently twice as expensive.
While solid-state cooking gets all the press, Ampleon is seeing better adoption for other RF energy applications, beginning with plasma lighting — purported to make marijuana plants grow faster — plasma generation for semiconductor processing and industrial heating and drying. Rather than trying to displace the magnetron in microwave ovens, the RF energy industry has adopted a flanking strategy: develop a new appliance. A rapid defroster using LDMOS power amplifiers offers commercial kitchens and consumers a value proposition based on saving time.
While offering GaN products, Ampleon remains bullish on LDMOS. Christoph Cugge, VP of marketing, confidently stated that at next year’s IMS, we’ll see 5 GHz products in LDMOS.
Custom MMIC now offers more than 135 MMIC products, covering all the RF functions in a transceiver and up to 50 GHz, and standard products contribute some 80 percent of revenue. At IMS, the company featured a number of new products, including:
- A 2 to 6 GHz ultra-low noise LNA with 0.6 dB maximum noise figure.
- Three GaN LNAs covering 2.6 to 4, 5 to 7 and 8 to 12 GHz, with 1.2, 1.2 and 1.8 dB noise figure, respectively. The advantage of GaN is power handling — 5 W for these LNAs — and recovery time, enabling many applications to forgo a limiter to protect the LNA.
- Four digital attenuators with performance to 30 and 40 GHz, in 2- and 5-bit configurations. The attenuators are available as die, with QFN-packaged versions planned.
- A 6 W, 26 to 28 GHz power amplifier, with typical power-added efficiency between 28 and 32 percent. This amplifier was initially developed for NASA.
For many systems with long lifetimes, product obsolescence is a concern. Custom MMIC has begun developing “equivalent” products using alternate foundries, to ensure a substitute product will be available should one foundry exit the market.
Unfazed by the notion that the existing ranks of GaAs, GaN and silicon RFIC suppliers have saturated the market, Duet Microelectronics quietly entered the industry in 2016, claiming “nobody understands and solves RF challenges better and faster.” Perhaps entering a crowded field is not a foolish notion, as four of the five members of the leadership team last worked at ANADIGICS, including CEO John Van Saders and CTO Bob Bayruns. So company management arguably understands the markets and technology as well as anyone. Duet has published a catalog comprising five product families:
- 450 to 6000 MHz LNAs for cellular and Wi-Fi.
- Power amplifiers for the 3.5 GHz CBRS band.
- Cable infrastructure amplifiers for DOCSIS 3.1.
- FTTx optical receive modules for DOCSIS 3.1 and China’s SART.
- Power amplifiers for 28 GHz 5G.
Perhaps most interesting is the use of InP for the 28 GHz power amplifiers, which Duet sees as a strategic advantage and a competitive technology for millimeter wave applications. The two InP power amplifiers cover the 27.5 to 28.35 GHz band with 24 and 27 dBm output power at 1 dB compression, greater than 38 and 40 percent power-added efficiency and a worst-case EVM of less that 2 percent RMS with a 256-QAM signal.
At ETL Systems booth, Dr Esen Bayar, Technical Director/CTO, explained the company’s expertise for “everything between antenna and baseband” for satcoms, and also talked about its offerings in fiber, handling signals from the antenna and transmitter. Based in the UK, the company’s product lines cover DC-40GHz and include L-Band routers, RF over fiber, switches, splitters/dividers, combiners and amplifiers. All of ETL Systems products are mission critical, so they have hot-swappable, redundant systems. For instance, the Enigma Matrix (consisting of 32 satellite inputs and 32 modems) was on display in the booth and is used for broadcast, intelligence gathering, and communications. (Different versions have different levels of security.) Other products in the booth included modular transmitter and receiver cards for converting RF to light, impedance conversion devices, and a waterproof transmission unit for GPS, which can be mounted on the outside of a building with one antenna and send timing data to multiple places within the building.
GLOBALFOUNDRIES announced a new ecosystem partner program a few months ago, called RFwave™, designed to simplify RF design and help customers reduce time-to-market for a new era of wireless devices and networks. The last few years there has been an increasing demand for connected devices and systems that will require innovations in radio technologies to support the new modes of operation and higher capabilities. The RFwave Partner Program builds upon GF’s 5G vision and roadmap, with a focus on the company’s industry-leading radio frequency (RF) solutions, such as FD-SOI, RF CMOS (bulk and advanced CMOS nodes), RF SOI and silicon germanium (SiGe) technologies. The program provides a low-risk, cost-effective path for designers seeking to build highly optimized RF solutions for a range of wireless applications such as IoT across various wireless connectivity and cellular standards, standalone or transceiver integrated 5G front end modules, mmWave backhaul, automotive radar, small cell and fixed wireless and satellite broadband. RFwave enables customers to build innovative RF solutions as well as packaging and test solutions.
Fabless MMIC start-up Guerrilla RF introduced two LNAs and a mixer at IMS and announced the company’s intent to offer AEC-Q100-certified products for the automotive market, beginning with three amplifiers. The two new LNA products, the first InGaP HBT MMICs offered by Guerrilla RF, are tunable over 100 to 3800 GHz and typically draw only 15 mA at 3.3 V bias. The mixer has single-ended inputs and outputs and requires an external image reject filter on the RF port and a bandpass filter on the IF; the RF and IF bands extend from 100 MHz to 5 GHz. The LO, with a frequency range from 100 MHz to 4 GHz, has an integrated LO buffer amplifier to reduce the external drive required.
IDT released mmWave beamformer ICs that are 4-element T/RX half-duplex silicon ICs designed using an advanced SiGe BiCMOS process for 5G phased-array applications. The IDT chips F5280 and F5390 address the three major worldwide bands of 24.25 to 27.5 GHz, 27.5 to 29.5 GHz, and 37 to 41 GHz. The core ICs have 5-bit and 6-bit phase control and more than 35 dB gain control on each channel to achieve fine beam steering and gain compensation between radiating elements. In transmit mode, the chips have 23 dB gain and 13 dBm OP1dB. In the receive mode, the receive gain is 23 dB with an NF of 5 to 7 dB and an IP1dB of -25 dBm, over the band. The core chips operate at 2.1 to 2.5 V and feature ESD protection on all pins. The core design includes standard SPI protocol that operates at up to 50 MHz with fast-beam switching, fast beam-state loading, and fast on-chip beam storage. The ICs also have four external bias pins (5-bit DACs) to control an optional external LNA/PA module and temperature reporting capability.
Infineon was showing off many solutions for 5G and smart sensors including smart home applications. They had a mmWave demo with beamforming for 5G cellular networks that was a 28 GHz demonstrator with Infineon chipsets BEA<28/BGT28UD - integrated 8x8 antenna array. There is a motherboard with digital electronics that connects to the RF module with the 8x8 antenna array on one side and the beamforming ICs on the other side. Each beamformer supports 4 antenna elements and the array has an ERIP of greater than 46 dBm. They were also showing off their smart home sensors of many types for monitoring everything in the home.

The company also has manufacturing facilities as well in Phoenix, where they are currently ramping up staff. They work with overseas partners for large volume production.
MACOM had many announcements including a portfolio of Non-Linear Transmission Line (NLTL) comb generators optimized to meet the demanding performance requirements of radar transceiver, VSAT and microwave radio applications. The industry-leading phase noise performance delivered by MACOM’s MLPNC Series comb generators is expected to significantly improve the overall performance of RF multiplier modules, complemented by a variable low input power profile (18 - 24 dBm) that relaxes the power requirements on power amplifiers and reduces overall power consumption. They also announced a portfolio of Ka-Band power amplifiers optimized for next-generation SATCOM and VSAT applications requiring uncompromising high-speed connectivity, efficiency and reliability. Available in 2, 2.3, 3, 4 and 6 W power output options spanning frequency ranges from 27 to 31.5 GHz, these new GaAs-based Ka-Band PAs are expected to provide industry-leading linearity and IM3, and best-in-class performance across a range of key metrics. MACOM’s Ka-Band MAAP Series PAs can deliver up to 24.5 dB of linear gain, 29% power added efficiency and saturated output power (PSAT) up to 38.5 dBm, with IM3 levels up to -25 @ 27 dBm. Another announcement was the availability of its new MADT-011000 power detector for use in applications spanning microwave radios, test and measurement (T&M) equipment and radar systems. Operating from 5 – 44 GHz and supporting high dynamic range of 30 dB (-15 to +15 dBm), MACOM’s MADT-011000 power detector features industry-leading wide-input bandwidth and device performance to enable optimal power control. The single-ended, internally-matched MADT-011000 consumes 70 µA from a 4.5 V supply, while the matched detector and reference diodes provide temperature compensation in differential operation. Additionally, they announced the newest entries in its high-performance RF switch portfolio. Optimized for use in SATCOM, 5G wireless, test and measurement, EW and microwave radio applications, the GaAs-based SPDT MASW Series switches provide best-in-class broadband frequency coverage and high-speed switching capability.

Morion recently published Precise Frequency Sources Meeting the 5G Holdover Time Interval Error Requirements with MWJ. Synchronization is an essential prerequisite for all mobile networks to operate. It is fundamental to data integrity; without it, data will suffer errors and networks can suffer outages. Radio base stations rely on having access to reliable and accurate reference timing signals in order to generate radio signals and maintain frame alignment. Effective synchronization also permits hitless handover of subscriber connections between adjacent radio base stations. The measurement of time interval error (TIE) is a method for evaluating reference timing signals and this article describes the process.

Finally, data is delivered to four DMA controllers linked to the PCIe Gen.3 x8 interface for transfer to a signal processor.
Although its focus is supporting Murata’s semiconductor needs, pSemi (formerly Peregrine Semiconductor) announced several new catalog products, for the first time tapping into semiconductor processes other than their historic allegiance to the UltraCMOS® SOI process.
For 5G massive MIMO base stations, pSemi introduced four switch+LNA modules integrating UltraCMOS switches with GaAs and silicon LNAs. Covering the 2.3 to 2.7 GHz and 3.3 to 3.8 GHz bands, the switch+LNA modules are offered in single- and dual-channel configurations. The designs comprise an input receive protection switch followed by a two-stage LNA — first stage GaAs and second stage UltraCMOS — with a bypass switch around the second stage. pSemi says the modules use 25 percent lower power and are 60 percent smaller than competitive GaAs solutions.
For millimeter wave applications, pSemi introduced a 9 kHz to 50 GHz DSA. In a flip-chip die format to maximize performance, the 6-bit design provides 31.5 dB dynamic range. pSemi also introduced four “value” DSAs covering various bands from 9 kHz to 6 GHz: 50 Ω 2-, 5- and 7-bit versions and a 75 Ω 6-bit DSA. Jim Cable, CTO, said pSemi invented the single-chip DSA in 2004 and these additions provide good performance at an attractive price.
Qorvo announced seven products in conjunction with IMS: five products for sub-6 GHz 5G infrastructure and two GaN front-end modules (FEM) for X-Band phased array radar.
The infrastructure line-up includes two GaN Doherty power amplifiers that provide 5 W average power from 3.4 to 3.6 GHz and 3 W average from 4.4 to 5 GHz. A companion wideband driver amplifier, matched to 50 Ω and fabricated with Qorvo’s enhancement PHEMT process, covers 1.8 to 5 GHz and provides 22 dBm output power at 1 dB compression. Two switch-LNA FEMs for base station receivers cover 1.8 to 4.2 GHz, with 1.45 dB noise figure, and 3.8 to 5 GHz, with 1.1 dB noise figure.
The X-Band FEMs integrate a T/R switch with LNA and power amplifier, all fabricated with Qorvo’s GaN process. The two designs cover 8.5 to 10.5 GHz and 9 to 10.5 GHz. The broader bandwidth design delivers 35 dBm saturated output power with 32 percent power-added efficiency and has 2.2 dB noise figure, while the narrower bandwidth FEM delivers slightly more power and efficiency — 36 dBm saturated and 38 percent — and 2.7 dB noise figure. Both are classified as EAR99, allowing them to be exported for most international programs.

Rohde & Schwarz had a demonstration of its new RTP line of performance oscilloscopes that are available in 4, 6, or 8GHz models. This product line is designed for higher memory depth and higher sample rates. What’s unique about this 8 GHz scope is that it performs its real-time processing in hardware rather than software, which improves speed. In standard acquisition mode, it can measure a million waveforms per second. R&S also demonstrated its NRQ6 frequency-selective power sensor that can zero in on a single signal (rather than just measuring all power). The company designed this for engineers who need to measure power below the -70 dBm noise floor (which in the past required a signal analyzer). The NRQ6 power sensor features a -130 dBm noise floor. Operating across 50 MHz to 6 GHz, it also captures I/Q data, and users can take data offline and process. The unit can perform band-limited continuous average power measurements (measurements on a selected transmission channel) up to a signal bandwidth of 100 MHz. Another highlight in the booth was the R&S SMB100B IoT signal generator (and companion SMBV100B vector signal generator) as part of the company’s mid-range class of instruments designed for the bench. With frequency ranges from 8 kHz to 1, 3, and 6 GHz, the newly released signal generators are available in various configurations. For instance, customers can choose among three different RF output power stages to scale the maximum output power to their specific needs. The generators can deliver up to +34 dBm output power (at 1 GHz carrier frequency) without an external amplifier.
Other instruments on display included: ZVA24 network analyzer: features upgraded output power for millimeter wave applications and can do power sweeps to examine amplifiers. It automatically configures to the converter chosen, handling converters up to 500 GHz (compatible with non R&S converters). Integrated converters for MPI probe station: Since much work on millimeter wave applications is on wafer, R&S’s customers were buying probe stations and it took a long time to get the converters configured correctly. So, the company created an integrated converter on an MPI probe station. ZNB VNA: Introduced three years ago, the ZNB VNA was enhanced last week for pulsed phase noise measurements that need stability from pulse to pulse, such as radar applications. The instrument is also used in high speed digital applications, such as in making a phase noise measurement of the reference clock for PCI Express.
