10 W high efficiency 14 V HBT power amplifier for space applications
07 October 2003
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 very high performances to be reached without manual tuning. The results of 10 W/PAE>65% obtained with a single chip at 1.5 GHz demonstrate the capability of the process to handle very high power densities and efficiencies.
