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
