In this paper, the design and nonlinear analysis of a dual-band mm-wave Doherty power amplifier is presented. The Doherty power amplifier has been designed to operate simultaneously at 24GHz for ISM band and 28 GHz for LMDS applications with 1 GHz bandwidth at each band, using Large-signal model of 0.15µm GaAs PHEMT transistor with 6 dB of output power back off at both frequencies.

This paper presents the design and nonlinear analysis of a mm-wave wideband Doherty power amplifier at 22 to 29GHz with 7GHz bandwidth, the design is done using 0.15μm GaAs PHEMT transistor to support a variety of mm-wave applications including point to point digital radio, LMDS/LMCS, ka-band satellite spacecraft and ISM applications. The wideband Doherty power amplifier provides greater than 21dBm...
