1.0 INTRODUCTION

1.1 GENERAL INFORMATION

This manual provides operating instructions for the DAMA certified TCR-MBA-

75 NBT Multiband Amplifier shown in Figure 1-1. The designation NBT (non-

bias tee) simply indicates the ability to use the amplifier without the need for a

bias tee by using the front panel DC connector. The TCR-MBA-75 NBT is

designed as a form and fit replacement for the AM-SAT-50 UHF SATCOM or

TCR-MBA-75 Amplifier with enhanced functionality. The footprint and

mounting provisions for the AM-SAT-50, TCR-MBA-75 and TCR-MBT-75 NBT

are identical. The TCR-MBA-75 NBT is an amplifier/pre-amplifier designed to

provide transmit and receive gain for:

 Multiband line of sight (LOS) 30~512 MHz communications;

 HAVEQUICK 225-400 MHz and SINCGARS frequency hopping 30~88

MHz operation; and,

 UHF Tactical SATCOM (242~268 MHz receive and 292~318 MHz

transmit) frequencies with Low Noise Amplifier (LNA) and Cosite

suppression.

Part number: 11000-00678

The TCR-MBA-75 NBT is 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 TCR-MBA-75 NBT Multi-band RF Amplifier operates in 30 MHz to 512

MHz AM and FM Line-of Sight (LOS), 30 MHz to 88 MHz SINCGARS Frequency

Hopping, 225 MHz to 400 MHz HAVEQUICK, and UHF Tactical SATCOM modes. It

is suitable for vehicular, airborne, or fixed-station applications and is compatible with

most military and commercial radios operating in the 30-512Mhz frequency spectrum.

The amplifier is weather-resistant and may be located outdoors with the antenna via Bias

Tee I (for information on this see Para. 2.3.3.1 Normal Operations). The operation of the

amplifier is controlled via front panel push button switches. The amplifier has a single

power connection, an RF input port and two frequency specific output antenna ports. The

LOS port is for frequency hopping and multiband Line of Site operation anywhere

between 30 and 512 MHz. The SATCOM port is used with UHF SATCOM antennas in

the 292-318 MHz uplink and 242-268 MHz downlink bands. The Mode push button

switch provides for selection of LOS AM or FM, SATCOM, Frequency Hopping

(SINCGARS), and Frequency Hopping AM (Have Quick). The LNA push button switch

allows the LNA to be enabled or disabled in SATCOM. The TX power push button

switch provides the amplifier output power selection in SATCOM mode. Some

equipment that is compatible with the TCR-MBA-75 NBT includes but is not limited to:

 LOS, multiband and SATCOM radios, including the AN/PRC-148 JEM and

MBITR, the AN/PSC-5 series, AN/PRC-117F, AN/PRC-117G AN/PRC-152

Falcon III Handheld, and the AN/PRC-119 SINCGARS terminals.

 Directional and broadband antennas with 50 Ohm impedance

 Conditioned power from a 28 VDC nominal source.

1.4 FEATURES

The TCR-MBA-75 NBT has the following features:

 JITC DAMA Certified

 Coverage from 30 to 512 MHz, including SINCGARS FM and HAVEQUICK

AM Frequency Hopping compatibility

 IW Compatibility

 Connections for both a SATCOM and an LOS antenna

 Pre-amplification of received RF signals from antennas in SATCOM mode

 Power amplification of transmit signals to 35, 50 or 75 Watts in SATCOM

mode

4 | Page

 Transmit and receive band filtering to suppress interference from

co-located radios and amplifiers in SATCOM mode

 Amplifier front panel indication of system status

1.5 TCR-MBA-75 NBT SYSTEM

The TCR-MBA-75 NBT is pictured in Figure 1-1.

1.5.1 Amplifier Components

The Amplifier consists of several printed circuit assemblies, a filtering and

switching network, and RF connectors housed in an environmentally sealed aluminum

housing. With normal care and maintenance, the assembly is highly resistant to corrosion

from the elements. The RF connections to the RF input, SATCOM and LOS antennas

are Female Type N. Power to operate the amplifier is applied via a cable connected to

the 5 pin circular Mil DC input connector. A 3ft Power cable is supplied with each

system.

1.5.2 Power Cable

A multi-conductor cable connects the amplifier with a 28 VDC power source. A

wiring diagram for the cable is shown in Section 3 of this manual. The cable is identical

to the power cable used for the AM-SAT-50 and AM-SAT-100 amplifiers.

1.5.2.3 Optional components

An optional Bias Tee I may be used to remotely power the TCR-MBA-75 NBT

and allow it to be placed closer to the antenna to over come system transmit and receive

losses and improve receive signal strength utilizing the built in Satcom Low Noise

Amplifier (LNA) in the TCR-MBA-75 NBT.
