1 System Description

Satellite payload applications related to communications and radar need multi-channel, high frequency transceivers. In these systems, there is a need to address different functions related to the communication channel across different bands, telemetry, and GPS. Although these functions can be independently created, integrating all functions into one design saves physical space and reduces complexity. The design requires radiation hardened active devices and space-grade passives to support operation in Low Earth Orbit (LEO) satellite applications.
