VERVIEW
The unit has three connectors on the input side of the housing and one waveguide port on the output
side. The interface for these connectors is detailed in this document.
On the input side, there are the following connectors:
J1 – Female N-type L-band IF Input
J2 – Ten pin circular connector
J3 – Four pin circular power connector
On the output side, there is one connector:
J4 – WR75 or WR62 waveguide RF output (specify at time of order)

BUC
The IF input is a 50 ohm type-N connector. The input is to be applied here (950-1700 MHz for Extended
Band; 950-1450 MHz for Regular Band). Also, the 10 MHz signal input is diplexed onto this line.
Therefore, the IF signal and 10 MHz reference are both traveling on this line. The connector is DC-
blocked. Do not exceed +/- 50VDC on this port.
The 10-MHz signal should be accurate within +/-20ppm, otherwise the BUC may have difficulty phase
locking to it. The 10-MHz should be free of sideband spurs, particularly close-in (under 100 kHz), as these
may also cause failure to lock. Power level of the 10 MHz reference signal should be +/-10 dBm.
