A key element of the solution is the NI Semiconductor Test System (STS), and NI recently demonstrated a multisite mmWave test solution for 5G power amplifiers, beamformers and transceivers.
NI/AWR discussed how the race to commercialize the many forms of 5G—faster broadband, mobility, and the Internet of Things (IoT)—is compelling RF, microwave, and millimeter-wave researchers and practitioners to take a smarter approach to microwave design and test. This new approach involves rethinking workflows. When development occurs in silos, information is not adequately shared across organizations. The NI software-defined platform prevents development in isolation by empowering teams to streamline concept-to-production workflows with interoperable software, such as the NI AWR Design Environment and LabVIEW. With these tools, organizations can accelerate product development, meet new and evolving test requirements, and manage aggressive time-to-market and schedule pressures. Demonstrations in the booth highlighted key features and applications such as:
- MMIC/RFIC, Module, & PCB Design Flows
- RF Amplifier & Filter Design
- 5G, IoT, & Radar Systems Design
- EM Analysis & Antenna Design

NXP introduced a family of LDMOS multi-chip modules (i.e., board products) for 5G massive MIMO systems. Each board contains an individually packaged PA, pre-driver, LNA and circulator. The boards have the same input and output and bias pins for all the power levels and frequency bands, i.e., 33 to 39 dBm average output power and 2.3 to 4.5 GHz. This common footprint simplifies base station design and shortens the development cycle for the range of cellular frequency bands. The PA, pre-driver and LNA ICs are also available separately for customers designing their own boards. Interestingly, NXP remains committed to LDMOS for the massive MIMO application — even to 4.5 GHz.
For mmWave base stations, NXP has developed 4-channel beamforming ICs fabricated with its internal SiGe process. Each channel contains a PA, LNA, T/R switch and vector modulator, for amplitude and phase control. NXP’s SiGe process delivers around 19 dBm compressed output power and better than 2 percent EVM when backed off to normal operating power. NXP argues their SiGe process provides the best system cost and DC power consumption compared to mmWave arrays fabricated with either SOI or GaN front-ends. To demonstrate the end application, NXP was displaying one of the company’s SiGe front-ends integrated with a Gapwaves mmWave antenna array.

WIN Semiconductors, the largest compound semiconductor foundry, made two announcements at IMS, strengthening the company’s position supporting mmWave systems. Not to be overshadowed by silicon and GaN, WIN announced the commercial release of its highly integrated E-PHEMT process, PIH1-10. The PIH1-10 platform combines a 100 GHz ft E-PHEMT with monolithic PIN and Schottky diodes, which support all the circuit functions in a mmWave front-end for 5G handsets, base stations and radios for backhaul and fronthaul. The single supply E-PHEMT achieves transmit power levels of 30 dBm and receive noise figure of 2.5 dB, and the integrated PIN diode has less than 1 dB insertion loss.
WIN also announced the commercial release of a 0.15 μm GaN on SiC process, the NP15-00, for mmWave PAs operating to 35 GHz. The GaN device, which is designed to operate at 20 V, uses a source-coupled field plate to improve breakdown voltage. The process, which runs on 100 mm wafers, enables through-wafer vias for low inductance grounding. At 29 GHz, the GaN device achieves 3 W/mm saturated output power with greater than 50 percent efficiency — without harmonic tuning — and 13 dB linear gain.
The Wireless Telecom Group featured product demonstrations from their Boonton, Noisecom and CommAgility segments, highlighting how each addresses customer needs. With communication systems using complex modulation, single tone gain and output power measurements and two-tone linearity measurements are no longer sufficient to measure component and system performance. Buying vector signal generators and signal analyzers to replicate and measure actual OFDM signals can be expensive. Alternatively, using a Noisecom broadband noise source at the input, to simulate the modulated signal, and a Boonton peak power meter at the output is an elegant and comparatively inexpensive method for measuring and assuring system performance. The technique measures crest factor, which is more sensitive to the initial compression which quickly degrades system linearity and data throughput. To add insight, the crest factor measurement can include the complementary cumulative distribution function (CCDF), a probabilistic assessment of system performance.
W. L. Gore & Associates (Gore) played a key role in the Apollo 11 mission and featured their Apollo story and artifacts at IMS 2019 in addition to products for 5G and aerospace & defense testing. Gore’s contributions to space exploration began very early in its history. In just ten years, the company went from a Delaware basement where the company was founded in 1958, to the moon with multiple products contributing to the success of the July 1969 Apollo 11 moon landing. Gore wire and cable supported getting men to the moon, was involved in the seismographic experiments on the moon, and helped the astronauts to navigate back home.
Wolfspeed demonstrated two GaN on SiC power transistors in the company’s booth at IMS: a 35 W, X-Band, 50 Ω matched PA for radar applications and a 60 W average (400 W peak) device targeting the 3.6 to 3.8 GHz 5G band in Korea. Although Wolfspeed sees GaN as the RF growth engine, it maintains the LDMOS portfolio acquired with Infineon’s RF power business. Wolfspeed’s marketing strategy is to let the market requirements and customer choose the “best” technology fit for the application. Simon Wood, the senior director of RF product development and applications, said the lower frequency, single cellular band applications favor LDMOS, while the multi-band and higher frequency PAs favor GaN, where GaN’s cost is offset by eliminating several single-band PAs or through operator OPEX savings.
Xilinx discussed applications for the Zynq® UltraScale+ RFSoC, from 5G infrastructure to defense systems. The RFSoC platform builds on Xilinx’s leadership in FPGAs, adding direct sampling 5 GSPS, 14-bit ADCs and 10 GPSP, 14-bit DACs. Now in its third-generation, the UltraScale+ RFSoC covers the full sub-6 GHz spectrum, and mmWave spectrum can be block down-converted to use the performance of the RFSoC. For massive MIMO radios, Xilinx estimates the UltraScale+ architecture will consume 50 percent less power and occupy 75 percent less board area. The capability and flexibility of the platform makes it applicable for cable PHY and phased array radar.
