Abstract
This paper describes a 28 GHz power amplifier with 4.5 W output power under CW operation. The amplifier utilizes four fully-matched MMICs, in which 0.35 /spl mu/m-long gate GaAs-based heterojunction FETs are employed. The developed power amplifier also provides the highest CW output power of 3 W over the bandwidth of 2 GHz at Ka-band.
