Electrical Interface
•M&C Connector –a ten-pin connector is used to interface with a host computer. See Section 2.3
J2 –Monitor and Control Interface for detailed description of the pinouts.
•Ethernet Connector –a six-pin connector is used to update the firmware and communicate with the
BUC/SSPA through the web-based ATOMControl interface. See Section 2.4 J3 –Ethernet port for
detailed description of pinouts.
•Power Connector –DC Units use a four-pin connector to provide power to the ATOM. See Section
2.6 J4 –DC Power for detailed description of pinouts.
•Ground Terminal –a #10-32 screw is used to ground the chassis during use.

1.3 Cautions and Warnings
W A R N I N G
Leakage Current
The ATOM may exhibit high leakage current during use. Ensure
that the ground terminal is grounded according to local
electrical codes prior to powering on the ATOM.
W A R N I N G
RF Radiation Hazard
The ATOM emits high power RF energy which is harmful to the
human body. Do not operate ATOM unless the RF output flange
is either terminated in an RF load (100W min) or connected to
the feed of a terminal.
Do not obstruct the RF output or feed output with any body part.
W A R N I N G
Do not allow equipment to be standing in water.
While the BUC/SSPA is designed to be used outdoors, the
equipment is not designed to operate in standing water. Failure
to follow this precaution could result in electric shock and injury
to persons.
C A U T I O N
Do not allow any items to fall into the unit from the waveguide
opening.
C A U T I O N
Apply voltage to the AC/DC input connector only as specified in
the original configuration of this unit. Application of a voltage
outside the specified range may cause the unit to become
damaged or non-functional.

Interface Control
2.1 Introduction
The unit has four 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 –IF or RF Input; N-Type Jack
•J2 –Ten-pin circular shell size 12 Amphenol connector for M&C (RS232/RS485)
•J3 –Six-pin circular shell size 10 Amphenol connector for Ethernet
•J4 –Four-pin circular shell size 12 Amphenol DC power connector
•J6 –Ground terminal

On the output side, there is one connector:
•J5 –WR75 waveguide RF output
•J5 Option: WR62 waveguide RF output for wide band

2.2 J1 –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
exceed +/- 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.
2.3 J2 –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.
