Power GaAs MMICs for E-band communications applications

This paper reports a new family of GaAs MMICs for E-band communications applications. Both single-ended and balanced versions are reported with minimum output power levels of 26 dBm and 28 dBm respectively for both the 71-76 GHz and the 81-86 GHz. bands. This is 3 dB (2 times) higher than the current state-of-the-art. The single-ended version of the low-band (71-76 GHz) MMIC demonstrated an output power density of 0.42 W/mm, which is the highest reported power density for GaAs at this frequency. Using a commercial 6-inch GaAs foundry process, these MMICs were developed to provide a low-cost solution for E-band applications.
