Abstract
The design of a Ka-band power amplifier is presented. The three-stage amplifier exhibits an output power of 0.5 watt with small signal gain above 16 dB across the 32 GHz to 34 GHz band. The amplifier is characterized using linear and nonlinear methods. The stability, especially odd mode stability, is carefully considered. Both schematic and EM simulation results are shown.
