Each individual amplifier will operate per specification when voltage is applied to each amplifiers output connector and will be
present at the input connector minus a diode drop

Voltage into the input connectors

10

28

Vdc

Each individual amplifier will operate per specification when voltage is applied to the input connector. Voltage will not appear
at the output connector.

20 Volts applied to DC LNB port

20

This voltage will power all six amplifiers and the 20 volts will be present at the input connector of each amplifier. No voltage
will be present at the output connector.

20 Volts applied to DC AMP port

This voltage will power all six amplifiers. No voltage will be present on the input or the output of the amplifiers
