High RF power levels are demanded to vacuum tubes amplifiers like TWT but this has the main disadvantage to use heated wires and bulky magnets or electromagnets. So, combined Solid State PA (SSPA) would be greatly appreciated if they could give at least the same order of magnitude in RF power levels, since in this case graceful degradation is increased.
Spatial power combining technique is certainly an alternative to combine many SSPA reducing to a minimum extent the combining losses. This is the RF technology utilized and optimized for the present project.
The present project aims at developing a monolithic K/Ka-band dual-circular-polarization antenna-feed system with integrated RF, thermal and mechanical functionalities, intended for GEO High Throughput Satellites.
