The Out Door Unitsatellite reception

Reception of Multiple Satellite Channels

Traditional:Multiple-Wire Separate Reception

Current:Simultaneous Reception Using Analog Single-Wire Multiplexer for Satellite Channel Stacking

Why developingnew ODU multiplexer?

Today (Analog Single-Wire Multiplexer ):

•8 Inputs

•8 saw filters (for channelization)

•3 Analog Switches ICs

•1 micro-controller IC

•1 FSK Modem IC

•15 W

Tomorrow (Digital Single-Wire Multiplexer ):

•14 Inputs (actually 12 required)

•5-th & 7-th LC filters (image rejection)

•.

•1 Digital Switch IC

•.

•8 W
