Inputs and Grounding
2.2.1 J1

IF/RF Input
BUC
The IF input connector is a 50 ohm coaxial connector (N or optional SMA Type). The external/internal
reference mode is auto-selected. If an external reference signal is applied, the BUC will switch to external
reference mode. In the absence of external reference signal, the BUC will switch to internal reference mode.
This connector is DC-blocked, and appears as a 50 ohm load at IF. Do not exceed ±50 VDC on this port.
SSPA
In the SSPA-only configuration, this is the RF input. It is a K-Type connector, with performance to 40 GHz.
No external reference is required for SSPA-only operation.

Ground Terminal
A #10
–
32 screw and lock washers are used to ground ATOM. Ensure the unit is grounded before powering
it on.

DC Power
The 25W, 40W & 50W ATOM Ka power input requires 18V to 56V DC power. Each ATOM is supplied with
a mating connector for the power interface.
Refer to specific configuration of the unit for the exact voltage range. Power is supplied through a four pin
type cylindrical connector. Two pins are used to deliver the positive connection and two pins are used for
the negative connection in order to reduce resistance. The negative connection is internally connected to
case ground. The negative power connection may alternatively be applied directly to the ground screw
terminal on the aluminum housing.
2.3.1 Connector Type
The J3 connector for the DC input is a four pin miniature circular connector. This connector is a MIL-C-
26482 Series 1 receptacle, shell size 12, 4 pin (Amphenol
®
71-533723-4P). The connector is a receptacle
with pins and requires the mating connector to be a plug with sockets (e.g Amphenol
®
PT06E-12-4S-SR).
A range of plug-compatible mating connectors 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 the Amphenol
®
catalog 12-070. Ensure the supply cable is capable of supplying at least
300W of power (for 25W ATOM Ka) or 600W of power (for 50W ATOM Ka).
