1.0 INTRODUCTION
1.1 GENERAL INFORMATION
This manual provides operating instructions for the DAMA Certified AM-SAT-50
Remote Bi-Directional Amplifier System shown in Figure 1-1. The system is a amplifier/pre-
amplifier designed to provide transmit and receive gain for UHF SATCOM channels, while
eliminating disruptive cosite interference on DAMA and non-DAMA 5 KHz and 25 KHz
channels.
The AM-SAT-50 has been DAMA Certified with several UHF SATCOM terminals.
For a listing of the current certifications please see the Joint Interoperability Test Command
(JITC) website.

1.3 EQUIPMENT DESCRIPTION
The DAMA Certified AM-SAT-50 Remote Bi-Directional Amplifier System is used to
provide transmit and receive amplification and cosite filtering for UHF SATCOM
communications. It is suitable for vehicular, airborne, or fixed-station applications and is
compatible with all UHF SATCOM radios. The Amplifier is weather-proof and is typically
located outdoors with the antenna. The Bias Tee is splash-proof and is usually located with the
radio, but may be placed anywhere between the radio and amplifier. The system connects in-
line with the radio and antenna with coax cable, with a connection for DC power input located
on the Bias Tee. There are operator controls located on the Bias Tee and the Amplifier. The
Bias Tee has a Power On/Off circuit breaker. The amplifier also has an auxiliary DC connector
for direct connection to a DC power source when a Bias-Tee is not needed (typically for
vehicle applications). The Amplifier has a three position switch to control receive gain, and a
Five position transmit power switch. The AM-SAT-50 interfaces with other equipment,
including:
Any UHF SATCOM antenna with a 50 Ohm impedance
SATCOM terminals, including the AN/PSC-5 and AN/PRC-117
Conditioned power from a source of +22 to +32 VDC
1.4 FEATURES
The AM-SAT-50 has the following features:
JITC DAMA Certification
Pre-amplification of received RF signals from remotely located antennas
Power amplification of transmit signals to 25, 35, 50 Watts
Transmit and receive band filtering to eliminate interference from co-located radios and
amplifiers
Amplifier front panel indication of system status

1.5 AM-SAT-50 SYSTEM
The AM-SAT-50 is pictured in Figure 1-1. A functional block diagram is
shown in Figure 1-2.
1.5.1 Bias Tee
The Bias Tee consists of two printed circuit assemblies in a divided aluminum housing.
The DC input connection and RF connection to the radio are located on one end of the Bias
Tee. The Power On/Off switch and RF connection to the Amplifier are located on the opposite
end. When assembled, the enclosure is splash-proof, and may be mounted in any convenient
position.
1.5.2 Amplifier
The Amplifier consists of several printed circuit assemblies, a filtering and switching
network, and associated connectors and switches housed in a watertight aluminum housing.
With normal care and maintenance, the assembly is highly resistant to corrosion from the
elements. The interconnections to the Amplifier are made via two female type N connectors.
Through holes are provided on the base plate for mounting purposes. A DC power connector is
provided on the amplifier for connection to a DC power source when remote operation is not
required, such as vehicle installations.
1.5.3 Power Cable
A five-conductor cable connects the AM-SAT-50 with a DC power source. A wiring
diagram for the cable is shown in Section 3 of this manual. The power cable may be attached to
either the Bias-Tee or directly to the amplifier.
