Abstract :
A 11 W high power amplifier for millimeter wave application is reported in this paper. The monolithic three-stage amplifier has been realized using a 0.15 μm T-gate field plated AlGaN/GaN high electron mobility transistors (HEMTs) in a microstrip transmission line technology on 3-inch SiC substrate. Saturated output power of 40.5 dBm and peak power-added-efficiency of 20% were measured at 29 GHz with the pulsed DC supply voltage of 24 V. Across the 28-31 GHz range, the amplifier delivers output power above 39.3 dBm with power added efficiency over 15%.
