1. The Out Door Unit
satellite reception

2. Reception of Multiple
Satellite Channels
Traditional:
Multiple-Wire Separate
Reception
Current:
Simultaneous Reception Using
Analog Single-Wire Multiplexer
for Satellite Channel Stacking

3. Why developing
new 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

4. Digital Single-Wire Multiplexer(DSWM)
for Satellite Channel Stacking
Simultaneous Reception
Using DSWM
