Theory of Operation

The ODPA is required to have a 10 MHz reference signal, and a +15 to 24 VDC supply
voltage from an L-Band Modem to the N-Type female connector (J3).

The ODPA will lock to the 10 MHz reference and then up convert an L-Band input signal
to the Ku-Band output frequency. It outputs this low level signal on Ku-Band OUT (J4).

The Ku-Band output from L-Band to Ku-Band BUC will feed to the RF Input (J1). The
SSPA will amplify the input Ku-Band signal from the BUC up to the desired output level.
