Microwave PA Thermal Design for SATCOM Systems
Jan 1, 2003
By Stephen D. Turner, and Ahmed M. Zaghlol For many years, solid state power amplifiers and traveling wave tube amplifiers have been in competition in communication services. This is particularly so in satellite communication systems. Currently, the highest RF output power achievable from microwave transistors is 60 W at 6 GHz and 20 W at 14 GHz. Not only is the DC to RF efficiency a concern, but the RF combining efficiency is also critical to the success of a solid state power amplifier....
