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. To this end, an EM in AlSi10Mg was designed and manufactured using the additive manufacturing process of powder bed fusion with laser beam. The EM successfully completed a space pre-qualification campaign, achieving a TRL near to 6.
Starting point for this activity was the EM design of a combined Tx-Rx Ka band feed chain, developed in a previous program.
This feed chain was further developed and qualified as EQM in a scalable feed cluster. The feed cluster consists of a waveguide panel, designed as beam forming network, carrying 16 horn-polariser assemblies.
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.
