This paper presents an Engineering Model of a fully integrated, hermetic receiver as developed for commercial space flight applications. Repeatable performance especially at K band frequencies is difficult and costly in a production environment. State-of-the-art packaging technology and a family of dedicated MMICs were employed in order to guarantee performance as well as reduce production and alignment costs. This combined with Alenia Spazio' s extensive, flight proven heritage, has produced a receiver aimed at both the transparent and regenerative payload markets.
This paper describes the design and development of channel amplifier and lineariser functions for Ka band satellite payloads. The units combine the latest erpertise in electrical design and technological implementation. GaAs MM1C technology is used to realise all the functions needed in the microwave section while advanced packaging techniques, such as low temperature cofiring ceramic, are employed to obtain a very compact and lightweight design.
