– IF/RF Inputs
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 Standard 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 within +/- 1ppm, 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 +/-5 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.

– Monitor and Control Interface
The M&C interface is used to control the unit with a host computer. All on-board sensors are accessed
through this interface. Use of this connection is optional. Each ATOM is supplied with a mating connector
for the M&C interface.
Monitor and Control Interface Pinout
The M&C interface is a ten-pin miniature circular connector. This connector is a MIL-C-26482 Series 1
receptacle, shell size 12, 10 pin (Amphenol® part number 93-533723-10P). A mating connector is
Amphenol® part number PT06E-12-10S-476. A range of compatible 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 refer to Amphenol® catalog 12-
070.
