TL;DR: The design of a low-cost FM-microwave satellite-ground-station receiver that is capable of accepting 12 contiguous color-television equivalent-bandwidth channels using a wide-band FM format and frequency division multiplexing (FDM) of the channels is described.
Abstract: The design of a low-cost FM-microwave satellite-ground-station receiver is described. It is capable of accepting 12 contiguous color-television equivalent-bandwidth channels in the 11.72-12.2-GHz band using a wide-band FM format and frequency division multiplexing (FDM) of the channels. Each channel has 36 MHz of usable bandwidth with a 4-MHz guard band and provides a CATV compatible output. The overall system specifications are first discussed. Then consideration is given to the design, fabrication, and evaluation of the different subsystems in the receiver.
