144-148 MHz RF AMPLIFIER

The model 1452G has the following features:

Linear all-mode operation with automatic T/R or P.T.T. switching and adjustable relay delay control. Linear operation allows SSB, FM, or CW operation with drive power levels usable down to 1/2 watt.
Receive GaAs FET pre-amplifier option available - factory installed or addable by us at a later date. Preamps use GaAs FET devices rated at .5db with + 18 dbm 3rd-order intercept point. The result is superior weak signal reception with improved strong signal intermod rejection.
Thermal shutdown protection built-in. Since extended transmission at full power produces temperature build-up in all amplifiers, a thermostatic switch is incorporated to protect the amplifier at temperatures exceeding +65oC.
Remote control feature available to switch in/out the amplifier and to defeat LED illumination (to drop current drain for rear trunk-mounted amps).
Excellent electrical and mechanical construction integrity using the best quality components and workmanship. User friendly controls are mounted on front panel with all RF and DC cables attached out of sight on rear panel. LED status lights on front continuously monitor the operating state of the unit. All models are manufactured in U.S.A. and carry a factory warranty.
Designed to ICAS ratings and meets FCC part 97 regulations.

COOLING ACCESSORIES :

The

Model ZM-OP1 is a 80mm slim fan and a fan grill.

By adding two noiseless fan ZM-OP1, 1452G's cooling performance is greatly enhanced.
