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 /- 50VDC on this port.
The 10-MHz signal should be accurate /-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.
SSPA
In the SSPA-only configuration, this is the RF input. It is a precision type-N connector, with performance
to 18GHz. No 10 MHz reference is required for SSPA-only operation.

The serial interface is used to interface the unit to a host computer. All on-board sensors are read through
this interface, including forward power monitoring. In default mute configuration (refer to section Pin D:
Shutdown (i.e. Mute Control) ), use of this connection is optional.

The monitor and control interface is a ten pin connector.
CAUTION: EXTREME CARE MUST BE USED WITH THIS CONNECTOR TO AVOID ELECTRO
STATIC DISCHARGE (ESD).
Many units have been damaged by improper ESD precautions. Always use
industry-standard practices including wrist straps when coming within six inches of these connectors or
any accessories or cables to be attached to this.
The connector is a cannon type connector with a 12-10 configuration with pins (Amphenol part number
71-533723-10P). This connector is a MIL-C-26482 Series 1 receptacle, Shell size 12, 10 pins. The
connector is a “receptacle” and it has pins (as opposed to sockets), and requires the mating connector to
be a “plug” with ten sockets. An example mating connector would be Amphenol #PT06A-12-10S. A range
of other plug-compatible Amphenol part numbers for the mating connector may be used to add options to
the plug such as right-angle, stress relief clamp, metal color/finish, etc. Please contact the connector
manufacturer for more information and/or see Amphenol catalog 12-070.
