Issue Draft A (2013-12-20)
shows the system structure of the ODU.
Multiplexer subsystem:
This subsystem performs the combining and dividing functions with the IDU interactive
signals.
IF subsystem:
This subsystem implements functions such as the frequency conversion, filtering, power
amplification, and AGC on the TX/RX IF signals.
Microwave subsystem:
This subsystem implements functions such as the frequency conversion, filtering, power
amplification, and AGC on the TX/RX RF signals.
Duplexer subsystem:
This subsystem implements functions such as antenna sharing, filtering, and isolation on
the TX/RX RF signals.
Control subsystem:
