1.0 INTRODUCTION

1.1 GENERAL INFORMATION

The TCR-U/L-50 Power Amplifier (PA) evolved from the widely fielded TCR-MBA-

50v2 to meet the demands for increased communication range of existing and emerging

handheld and manpack radios utilizing UHF and L-Band waveforms. The PA is

designed for use with UHF narrowband as well as UHF and L-Band wideband

waveforms and shares the same footprint as the TCR-MBA-50v2.

• Transmit amplification for the 225-450 MHz, 1.25-1.45 GHz (L1), and 1.75-

1.85 GHz (L2) frequency ranges

• Four co-site filtered receive bands: 225-320 MHz, 225-450 MHz, 1.25-1.45

GHz, and 1.75-1.85 GHz

• Low Noise High Dynamic Range Receive Pre-Amplifier (LNA) for all bands

• Two automatic switching antenna ports: UHF and L-Band

• Active and DC Off/Failsafe L-Band Bypass

• Carrier Detect Keying and Automatic Frequency Detection

• UHF SATCOM, DAMA/IW

• UHF FM, UHF AM, HAVEQUICK II

• ANW2C and SRW Wideband Networking

• Tactical Waveforms mode for advanced waveforms

• Advanced Special Communications Mode (ASCM)

• RS-485 and USB connectivity for end-user devices and optional Remote

Face Plate and Bias-Tee

• Simple, three button menu-based user interface with Night Vision Goggle

(NVG) compatible display

• MIL-STD-810G, MIL-STD-461, MIL-STD-464 (Near Strike Lightning)

• Excessive temperature, voltage, and current protection

1.3 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.

1.3.1 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:

RCV FILTER MODES

UHF SATCOM SATCOM

UHF UHF FM, UHF AM, HQ (HAVEQUICK), WB

(WIDEBAND), and TW (TACTICAL WAVEFORMS)

L1 WB and TW

L2 WB and TW

BYPASS BYP L-BAND

1.3.2 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.

1.3.3 OLED DISPLAY

The TCR-U/L-50 NVG compatible OLED Home Display is used to indicate the mode of

operation, power level, antenna selection, DC input power, internal temperature, RCV/TX, and

in use antenna when in AUTO. During use of the Menu function, the display provides clear

user instructions. Examples of the Home Display and Menu functions are shown in Figures 1-2

and 1-3.

1.4 AMPLIFIER COMPONENTS

The TCR-U/L-50 Power Amplifier has a sealed, rugged enclosure finished in black anodize and

designed to withstand the elements and resist corrosion. The enclosure houses all electronic

subassemblies including printed circuit board assemblies, filter and switching networks, and

interconnects.

1.5 POWER CABLE

A multi-conductor cable connects the amplifier with an external DC power source. A cable

wiring diagram cable is shown in Section 3.3 of this manual. The DC power cable used with the

widely fielded TCR-MBA-50 family of PAs may be used to power the TCR-U/L-50.
