Abstract :
This work reports the design of a GaAs monolithic K-band Doherty power amplifier for point-to-point microwave backhaul applications. The design of the module is described, from the choice of the architecture based on power budget and gain requirements, to the analysis of the solutions adopted. The MMIC is expected to achieve 32.5 dBm output power in the 20.8-24 GHz band, PAE higher than 32% at saturation (20% at 6 dB output back-off) and gain higher than 10 dB.
