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
