All the SSPA functionalities, i.e. power supply, power conditioning and RF amplification, are integrated in the developed architecture and accommodate in a unique box with limited volume and mass. The required output power level is achieved by parallelizing several GaN die power bars of 12 mm and/or 26.5 mm.

Abstract

This paper describes the preliminary results attained in the framework of the European Project named SLOGAN. It aims to develop, using European GaN-HEMT technology, a ready-to-fly 230 W solid state power amplifier (SSPA) for space borne Galileo System. The idea is to offer a valid alternative to replace travelling wave tube amplifiers with more compact and reliable systems. All the SSPA functionalities, i.e. power supply, power conditioning and RF amplification, are integrated in the developed architecture and accommodate in a unique box with limited volume and mass. The required output power level is achieved by parallelizing several GaN die power bars of 12 mm and/or 26.5 mm. Test results on preliminary prototypes have shown efficiency levels higher than 68% with less than 3dB of compression in the wall E1-Band.
