Abstract
A hybrid, 2-stage, high electron mobility transistor (HEMT) power amplifier is reported operating over the 32-35-GHz band with a minimum output power of 28 dBm. At 34 GHz, an output power of 0.8 W with an associated power-added efficiency of 26.6% has been demonstrated. Biased for efficiency, this amplifier has demonstrated a power-added efficiency of 32.2% with an output power of over 0.7 W.<>
