EQUIPMENT DESCRIPTION 

 

The TCR-U/L-50 (Tricom PN: 11000-00927) is a bi-directional half duplex RF Power Amplifier 
(PA) designed to enhance communications in vehicular, airborne, maritime, man-portable, or 
fixed-station applications. Current military and commercial waveforms are supported including 
Narrowband LOS (UHF FM and AM), Frequency Hopping, DAMA/IW SATCOM, Wideband 
Networking and Special Communications Modes. Four individual receive band co-site filters 
with high dynamic range low noise amplifiers (LNAs) are used to cover the UHF SATCOM, 
UHF, L1, and L2 ranges to greatly improve reliable communications in high co-site installations. 
Harmonic filters are used to control harmonic and spurious emissions. The L-Band Bypass mode 
suppresses frequencies below 30 MHz. An intuitive menu driven user interface simplifies 
operation of the PA and provides status to the operator.

MODES AND RECEIVE FILTER SELECTION 

 

Listed below are the receive band filter ranges with the associated PA modes. The PA 
modes are listed in the format that they are displayed. Mode selection is accomplished 
using the TCR-U/L-50 front panel push buttons, further described in Section 2.3:

TRANSMIT POWER LEVELS 

 

The PA has 10, 15, 20, 35, and 50 Watt RF output power levels for UHF narrowband modes and 
10, 25, and 50 Watt levels for WB and TW operations.  Note, L-Band is limited to 25W output 
power.
