RF and millimeter wave amplifiers are key elements in modern wireless and defense applications. Existing high speed transistor technologies are approaching their limits and current amplifier design practices focus on trade-offs between key performance parameters. With 5G deploying and upcoming millimeter wave systems for defense, next generation GaN transistor technologies are emerging.

Load modulation based power amplifiers have been the workhorses in wireless networks for more than two decades. In this session, load modulation techniques are further enhanced, for their RF bandwidth, through the use of balanced structures and inverted DPA topologies. In addition, Doherty efficiency is further improved in power back-off by means of digitally controlled signal injection. 5G MIMO base stations needs are addressed including DPA miniaturization through MMIC integration, as well as, the capability to handle large video bandwidths.
In this joint ARFTG-IMS session, a number of riveting nonlinear measurement topics are discussed. We begin with new error vector magnitude results on GaN power amplifiers. Additional papers cover synchronized, modulated nonlinear vector network analyzer measurements, multitone amplifier linearity characterization, and pulse profiling load pull analysis.

In this session, we have two papers describing advanced DPD techniques for massive MIMO applications, considering OTA identification and predistorter complexity; and three papers describing novel approaches for envelope tracking power amplifiers, including a GaN MMIC modulator design, a floating source RF PA, and a novel Marx generator-based modulator.
This session is on advanced radar systems and concepts for automotive and vehicular applications. The topics range from modulation schemes for MIMO radar and in-depth analysis of radar noise performance, to concepts for speed over ground estimation and model-based and neural-network based super-resolution range and angle-of-arrival estimation techniques.
The session will showcase state-of-the-art advancements in silicon-based power amplifier architectures and technology for 5G and automotive applications. The session will demonstrate techniques that range from broadband design and back-off efficiency enhancement to fully digital PA architectures. The first five papers demonstrate these techniques from 22 to 90 GHz and the last paper discusses a novel hybrid digital transmitter architecture combining CMOS and LDMOS technologies for base station applications.

Advanced FinFet and CMOS SOI processes demonstrate PAs at 28 GHz and E-band. Novel approaches to load modulation are demonstrated in a multi-element transmit array. Finally, a state-of-the-art broadband receive beamformer is demonstrated with low noise figure.
Microwave and millimeter wave transmitters and receivers have been developed in Si technologies, which is attractive for the development of networked and distributed systems. Such systems promise much better imaging and or sensing properties than single transceiver systems. This session addresses such systems, in particular architectures, hardware realizations, the impact of hardware impairments, and low level signal processing approaches.
Presentations within this session include integrated front ends for a wide range of frequencies used in phased arrays. This session will commence with two radar papers, followed by a Ka-band communication front end and an 8-channel K-band phase shifter, and will conclude with a wideband GaN front end.
