Systems using a single transmit RF waveguide
switch (transmit-only)
In the transmit path, a single transmit RF waveguide switch
directs the transmitted RF from the on-line BUC to the
transmit port of the antenna feed. The RF from the off-line
BUC is directed into an appropriately-rated termination. The
switch is controlled by a cable connected to the LNB Switch
Control connector.
The switch is an electrically operated, 4-port WR137 (for
C-Band) or WR75 (for Ku-Band) waveguide transfer switch.
The BUCs are connected to ports 1 and 3 of the switch. The
switch is coupled via port 2 to the transmit port of the antenna.
A load or power attenuator connects to port 4.
The redundancy controller verifies RF waveguide switching
by monitoring the tell-back contacts to the RF waveguide
switch. If the tell-back contacts indicate an abnormal
condition, the BUC Switch LEDs on the control panel of the
redundancy controller illuminate red.
