IMS2022 was close to back to normal with about 6500 total attendees and 450 exhibiting companies in Denver – a great sight to see. The mood was very energetic, and everyone was very happy to see each other since it was close to two years since many had been together. As 5G and SATCOM continue to be areas of growth, it is good to see some new emerging markets like 6G, quantum and hypersonics gaining momentum.

A couple of very interesting new technologies were a transparent antenna-on-display solution and the emergence of RF Glass. KREEMO and Sivers Semiconductors announced that they have successfully demonstrated data communication between transparent antenna-on-display devices based on SUMMIT2629, a 28 GHz beamforming chip, and stackable patch antenna devices with 360-degree beam coverage. The SUMMIT 2629 is a RFSOI eight-channel RF beamforming IC for 28 GHz and extends link range and reduces power consumption while optimizing antenna array complexity. KREEMO has the first transparent antenna-on-display technology that implements mmWave antennas on displays and stackable patch antenna technology that provides 360-degree coverage. The products jointly developed and supplied by KREEMO and Sivers Semiconductors are the transparent antenna-on-display module, the 1x4 stackable patch antenna module with a 360-degree beam coverage, a 4x4 AiP module (scheduled in 4Q), a 4 x 4 stackable patch antenna module with a 360-degree coverage (scheduled in '23 2Q) and the antenna development kit 360° (ADK360°). This is a very interesting technology and development.

There were at least two exhibitors designing and supplying high performance RF Glass circuits. 3DGS and ED2 both offer this process with 3D Glass ready for production on 8-inch wafers. 3DGS leverages the properties of a patented APEX® glass-ceramic material with excellent electrical performance and ultra-low transmission loss at high frequencies ranging from 1 to 200 GHz. Using traditional semiconductor processes, 3DGS produces high-precision, high volume-scale components that meet the needs of consumer, commercial and mil/aero system designers. The process supports passive components including antennas, baluns, filters, inductors, capacitors and couplers, etc., and can use air in passive component design for very high performance.

ED2 has designed a C-band bandpass filter that is a high performance, low cost, BGA-type surface mount component. The filter typically has a <3 dB insertion loss over a MHz bandwidth. The filter’s excellent rejection makes it perfect roofing filter in complement to SAW and BAW applications and is also highly repeatable from filter to filter.

In addition, Keysight was featuring a 6G demonstration with Nokia Bell Lab's D-band radio-on-glass transceiver with an active phased array antenna module which highlights Keysight's 6G testbed's ability to enable wide-bandwidth measurements and explore ultra-high data throughput scenarios.

Aethertek  showcased their Open RAN RU, mmWave antenna in module (AiM) and OTA test solutions supporting FR1 and FR2 mmWave bands at the workshop. Open RAN Radio Unit Aethertek’s O-RU supports FR1 and FR2 mmWave frequency bands, and it is developed according to ORAN standard Option 7.2, using eCPRI interface to connect with DU. In addition to the built-in FR1 antenna, it is also integrated with Aethertek’s mmWave module IRIS to achieve ultra-high speed transmission with dual-polarization of 400 MHz bandwidth.

Akoustis Technologies promoted the capabilities of its XBAW filter technology for Wi-Fi 6 and Wi-Fi 7, as well as RFM Integrated Device’s (RFMi) catalog portfolio of SAW, crystal oscillator and ceramic products. (Akoustis completed the acquisition of RFMi earlier this year.) Wi-Fi is currently driving the company’s growth because of the transition from LTCC and ceramic filters to BAW. With the added frequency bands of Wi-Fi 6 and 7, system architectures are moving to tri-, quad- and penta-band with tough filtering requirements that play to the strengths of XBAW. Akoustis is also pursuing design wins in smartphones and has five active customer engagements, one of which may reach volume production in 2023. To support these volumes, Akoustis has increased the capacity at its fab in upstate New York to around 500 million filters per year. XBAW’s differentiation stems from the starting piezoelectric material and the transfer flow process used to fabricate the filter, which yield higher Q. During IMS, Akoustis announced an award from DARPA that aims to extend XBAW filter technology to 18 GHz.

Altum RF showcased its featured products and technical expertise in booth 3012. Company leaders were in the booth answering questions about specific products, future plans and their decades of experience designing and delivering RF, microwave and mmWave semiconductors.

Ampleon featured GaN and LDMOS PAs from its two business units, Mobile Broadband and Multi-Market. Ampleon’s product development strategy is agnostic: choose the process technology that best meets market needs. For macro base stations, particularly at frequencies above 3 GHz, GaN’s efficiency, bandwidth and high power density — which yield smaller size — is generally preferred. However, an LDMOS driver is often used because it provides easier linearization with DPD and yields a lower cost lineup. Also, LDMOS remains viable for the output stage in many cellular bands, such as sub-1 GHz. For mMIMO, Ampleon offers several solutions: discrete output and driver stages, PA modules integrating the driver and output stage and integrated modules adding the bias control circuitry. Although discrete solutions provide better performance, the trend is toward integrated modules because of the limited size available in mMIMO arrays with 32 and 64 elements. For small cells requiring output power above a couple watts, Ampleon favors integrated Doherty PAs using LDMOS because of its efficiency advantages over 5 V technologies such as GaAs HBT. A live demo of a base station transmitter was featured in the AMD-Xilinx booth, showing the performance of the AMD-Xilinx RFSoC and digital front-end married to an Ampleon base station PA using a GaN output stage and LDMOS driver.

dSPACE offers the high-precision digital DARTS 9030-M, which benefits from the expertise of dSPACE development partners ITS and mirosys. It offers 1.2 GHz of usable bandwidth and covers a frequency range from 75 GHz to 82 GHz. The precision of the device is demonstrated by the fact that the range increments of 6 cm are consistent throughout the simulation range from 5.5 m up to 1,000 m with a simulation accuracy of less than 1 mm. This applies in conjunction with a dynamic range >60 dB. The advantages of the digital concept are even more evident considering the multi-target simulation capability: Up to four fully independent targets can be simulated without compromising the signal quality. dSPACE is in the process of improving the DARTS 9030-M by means of software updates. These updates will fulfill requirements related to the fast switching of simulation distances. Stay tuned for more details in the near future.

Rohde & Schwarz highlighted its latest solution for optimizing Error Vector Magnitude (EVM) capabilities, based on the R&S SMW200A vector signal generator (VSG), which now covers up to 67 GHz, and the R&S FSW signal and spectrum analyzer. Accurately measuring EVM has become a key specification for both the device-under-test and the test instrumentation, as it encapsulates many critical test parameters. The R&S FSW has been the leading instrument for high-end measurements requiring extreme precision. Its new front end continues the path of innovation with unrivalled EVM measurement accuracy for wideband modulated signals in the mmWave range. This makes the solution ideal for testing any high-end communication component or systems, including 5G NR FR2 or IEEE 802.11ay / ad chipsets, amplifiers, user equipment and base stations. The R&S FSW is complemented by the R&S SMW200A vector signal generator. When it comes to creating complex digitally modulated signals, 44 GHz has been the limit for high-accuracy standalone vector signal generators. Higher frequencies have only been possible with additional external equipment and limitations in accuracy. Now, the R&S SMW200A from Rohde & Schwarz dramatically raises the limits for generating wide bandwidth signals of high quality with two new options for maximum frequencies. The 100 kHz to 56 GHz option covers all currently used 5G frequencies, plus earth-to-satellite applications. The 100 kHz to 67 GHz option also supports planned higher frequency 5G bands, the 60 GHz WiGig band, and inter satellite links. In another highlighted demo, Rohde & Schwarz will present an R&S ZNA vector network analyzer (VNA) used for 6G D-band system and component characterization. Key industry players have identified the D-Band, ranging from 110 GHz to 170 GHz, as a candidate frequency band for 6G mobile communications, as well as for future automotive radar applications. Additionally, show attendees will be able to experience up close the R&S ATS1800C CATR based 5G NR mmWave Over-The-Air (OTA) test chamber, which provides the ideal environment for testing 5G FR2 antennas, modules and devices from R&D to conformance. When equipped with the two side chamber extensions, a unique 3D quiet zone is formed, with which the test solution even supports on a very small footprint RRM measurements including multiple angles of arrival (AoA).

Samtec demonstrated a flexible waveguide that is being developed in conjunction with Vubiq Networks.

Tagore Technology is a fabless semiconductor company founded in 2011 to provide GaN on Si RF and power electronics components. At IMS, it exhibited the RFIC portfolio, including GaN RF switches, GaN PAs and GaN and GaAs LNAs. Tagore’s second-generation switch designs cover the sub-6 GHz bands and offer lower insertion loss and higher power handling: 10, 20, 50 and 100 W in two- and four-throw options. GaN switches are driven with 5 V and draw only microamps current, significant advantages compared to PIN diode switches. Complementing the switch products, Tagore has designed several broadband PAs for portable land mobile and military radios, where a single GaN device can cover 30 MHz to 2.7 GHz. Because of the bandwidth, the PAs are attractive replacements for LDMOS amplifiers. While GaN can be used for LNAs, the 1.2 to 1.5 dB noise figure is not competitive with what can be achieved with GaAs PHEMT designs. So Tagore has developed several GaAs LNAs with typical noise figure of 0.4 dB for applications to 6 GHz.

Taitien released a miniature ultra-low power /low g-sensitivity OCXO, NH-7500 Series,  in a small 15 x 15 mm footprint the NH7500 offers ultra-low g-sensitivity of 0.3 ppb/g and ultra-low power requiring only 95 mW of power at 25°C for a wide -40 to +85°C temperature range. Available from 10 MHz to 40 MHz the NH-7500 is ideal for battery-powered applications such as portable test equipment, mobile communication systems and emergency rescue devices.

The RF strategy being pursued by Texas Instruments (TI) can be summarized as the digitization of RF. As an opening bid, a wide bandwidth, multi-channel transceiver integrates four transmitter (Tx), four receiver (Rx) and two sampling paths handling RF frequencies from 600 MHz to 12 GHz. At IMS, TI demonstrated the spectral purity of this transceiver, the AFE7950. Transmit processing supports 1.2 GHz signal bandwidth with four Tx or 2.4 GHz with two Tx channels. The maximum receive signal bandwidth is 1.2 GHz without the feedback channel or 600 MHz with it. Just prior to IMS, TI raised its bid with a new analog-to-digital converter (ADC), the ADC32RF54, a 14-bit, dual-channel, 2.6 GSPS ADC developed for phased array radar, EW, software-defined radio and test and measurement systems. TI’s design uses a non-interleaved ADC architecture with four ADC cores per channel. Averaging the four signals reduces the noise floor, improving the dynamic range. To drive the ADC, TI offers high frequency differential amplifiers which convert a single-ended input from the RF front-end to the differential signal required by the ADC.

Wolfspeed exhibited its portfolio of GaN devices for both 5G and defense markets. For base station PAs, GaN is Wolfspeed’s preferred technology, although it continues to support the LDMOS products it acquired from Infineon — still getting some LDMOS design wins. However, GaN has the advantage of wider bandwidth and continues to take share from LDMOS. Wolfspeed tailored its second generation GaN to improve performance, enabling wider instantaneous bandwidth (200 to 300 MHz) and reduced trapping to improve linearity with DPD. For mMIMO systems, Wolfspeed offers both discrete devices and integrated modules. At IMS, the company demonstrated a GaN transistor that supports all the cellular bands below 1 GHz. Although different Doherty network designs are required, this single transistor can be used for all the bands, giving GaN an edge over LDMOS. For the defense market, Wolfspeed sees attractive opportunities in radar, EW and military communications, with the strongest demand for radar systems. To better support the defense market, Wolfspeed is introducing pallets — integrating the power transistor with the matching circuitry on a single circuit board — and demonstrated an S-Band radar pallet at IMS.
