Abstract

This paper presents the first development of a space-borne power amplifier using the recently developed high breakdown,high Power HBT HB20S process of UMS.The inverse F class Hybrid Power Amplifier has been designed using intensive simulation methods developed at Alcatel Space for MMICs,allowing to reach very high performances without manual tuning.The results 10 W /PAE >65%obtained with a single chip at 1.5 GHz demonstrate the capability of the process to handle with very high power densities and efficiencies.
