A hybrid power amplifier building block and a power amplifier module from 2 GHz to 6 GHz were designed, fabricated and measured. These power amplifiers are all based on AlGaN/GaN HEMT technology.
The future applications for these types of power amplifiers are mainly electronic warefare (EW) applications. Novel communication jammers and especially active electronically scanned array EW systems have a high demand for broadband high power amplifiers. Output power levels with a peak value of 90 W at lower frequencies and more than 40 W up to 6 GHz are measured. With these power amplifiers novel EW system approaches can be investigated.
