In this paper, we report the preliminary results of an Engineering Model of a complete SSPA, developed for Galileo satellite system (E1 band, 1575.42 MHz), and based on UMS GaN (GH50-10) technology. The SSPA includes also satellite interfaces (e.g., internal power supply generation unit, telemetry and telecommand functionalities) and measured results show an output power larger than the targeted 230W, with a PAE greater than 40%. Moreover, a very good stability in frequency was measured, with a gain ripple lower than 0.5 dB in 50MHz of bandwidth, and less than 0.2 dBpp in 10 MHz.

Abstract
In this paper, we report the preliminary results of an Engineering Model of a complete SSPA, developed for Galileo satellite system (E1 band, 1575.42 MHz), and based on UMS GaN (GH50-10) technology. The SSPA includes also satellite interfaces (e.g., internal power supply generation unit, telemetry and telecommand functionalities) and measured results show an output power larger than the targeted 230W, with a PAE greater than 40%. Moreover, a very good stability in frequency was measured, with a gain ripple lower than 0.5 dB in 50MHz of bandwidth, and less than 0.2 dBpp in 10 MHz.| File | Dimensione | Formato | |
