Abstract
A high efficient, low distortion L-band power module using a linear and non-linear models of the HFET devices has been developed. Single stage hybrid amplifier fabricated with 4x18mm gate width HFET exhibits an output power of 43.8dBm, a linear gain of 17dB and an associated PAE of 60% at 1.5GHz. These excellent results are performed by developing an accurate non-linear model of the chip device and optimizing the matching networks of the amplifier.
