| Abstract(in English) | This paper describes design consideration and performances of a Ka-band power amplifier. The amplifier utilizes four fully-matched MMICs, in which 0.35μm-long gate GaAs-based heterojunction FETs are employed. The developed power MMIC amplifier delivered an output power of 1.0W at 28GHz. Same matching circuits with easy configuration are applicable for both input and output matching circuits by combining four fully-matched MMICs. The power amplifier demonstrated an output power of 3.0W and a power-added efficiency of 20.5%. The highest output power of 4.5W was achieved. The developed power amplifier also provides the highest CW output power of 3.0W over the bandwidth of 2GHz at Ka-band. |
