Abstract
A high efficiency multiple power level power amplifier has a PIN diode network that selectively associates an impedance transformation network with an interstage impedance matching network to maintain desired gain and linearity characteristics for the power amplifier at different output power levels. The PIN diode network in the off mode (high power), has a high breakdown voltage and high series resistance thereby reducing distortion components. The PIN diode network in the on mode (low power), has a low series resistance thereby reducing insertion losses.
