Abstract
A high performance 38 GHz monolithic pseudomorphic high electron mobility transistor (PHEMT) power amplifier has been developed for commercial millimeter-wave radio systems. This highly integrated MMIC chip has three power PHEMT stages and achieved 25 dBm 1-dB compressed output power with 19 dB power gain using 6V drain-source bias. The MMIC process utilized an optimized power PHEMT structure and has demonstrated high yield with excellent reproducibility making it suitable for high volume commercial applications.
