Introduction
1.1 OVERVIEW
This operator’s manual applies to all ATOM SSPAs and BUCs with the following marketing numbers:
ATOMSKAxxx (25-50W)
ATOMBKAxxx (25-50W)
ATOM-100060 (40W)
This includes any ATOM that uses the 25-50W (Psat) Ka Commercial Band (29.0-30.0 GHz), Military Band
(30.0-31.0 GHz), Dual Band (29.0-30.0 GHz / 30.0-31.0 GHz) or Specific Bands. This also includes the
ATOM-100060 (Ka 40W BUC) as specified.
SSPA - Solid State Power Amplifier
If this unit is a SSPA, the RF input signal is amplified to the specified power.
BUC - Block Up Converter and Amplifier
If this unit is a BUC, the IF input signal is upconverted to Ka-Band RF frequencies and then amplified to the
specified power.

Electrical Interface
M&C Connector –a ten-pin connector is used to interface with a host computer. See Section 2.4 J2 –
Monitor and Control Interface for detailed description of the pinouts.
Power Connector –DC Units use a four-pin connector to provide power to the ATOM. See Section 2.3 J3
–DC Power for detailed description of pinouts.
Ground Terminal –a #10-32 screw is used to ground the chassis during use.

1.4 SAFETY
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.
