Abstract
In this paper the development and measurement results of a compact broadband 9-Watt high-efficient X-band high-power amplifier are discussed. The described amplifier has the following state-of-the-art performance: an average output power of 9 Watt, a gain of 20 dB and an average Power Added Efficiency of 35% over a relative bandwidth of 40% at X-band. The amplifier is realised in a pseudomorphic HEMT GaAs MMIC technology developed by the Fraunhofer Institute for Applied Solid State Physics (FhG-IAF) in the scope of the WEAG/TA1/CTP8.1 program.
