Abstract :
In this paper the design of a two-stage class F high power amplifier made up by ten active devices is presented. The design is based on a new approach for combining the devices and designing the matching networks. The amplifier has been designed for synthetic aperture radar applications by using SELEX 0.6mum GaAs PHEMT technology. The design approach will be discussed and simulation results will be presented. In particular, 38.5dBm output power with 40% power added efficiency has been obtained at 9.6GHz in an operating bandwidth wider than 10%
