K-Band Doherty and Class AB Gallium Nitride MMIC Power for Space Application


This paper compares the performance of Class AB and Doherty Gallium Nitride (GaN) Power Amplifier (PA) MMICs at 19GHz. The MMICs have been designed in the same process and fabricated on the same wafer to enable the ability for direct performance comparison. Measurements of the AM/AM and transfer curves, Linearity, and Power Added Efficiency have been made for each MMIC PA. Finally an assessment of these performance parameters with respect to output power backoff (OBO) will be presented to help normalize the comparison. To the authors knowledge this is the first time these power amplifier architectures have been compared at these frequencies (2). Additionally, to the best of the author’s knowledge the performance for these amplifiers show state of the art PAE for GaN PA MMIC amplifiers at these frequencies.


mmTron Develops mmwave Packages To 60 GHz

mmTron Inc, a leading provider of mmwave high linearity MMICs and integrated transceiver modules, has developed a surface-mount package for high power mmwave products. With a similar footprint to the widely used QFN, mmTron mmwave package simplifies and lowers the cost of mmwave assemblies. mmTron mmwave packages allow for standard solder attachment to PCB, eliminating the cost and complexity of wire bonding.

mmTron is experienced in custom MMIC and integrated transceiver modules

in the millimeter wave frequency range, e.g. 5G FR2, Ka, Q, V, E and W bands. mmTron has filed patents covering its core technologies including semiconductor and proprietary circuit designs. Corporate headquarter is in Bay Area, CA. For more information on the mmwave packages, along with mmTron’ complete portfolio of products, IP and design services for mmwave visit
