5765
25 WATT DIGITAL AMPLIFIER
SYSTEM DESCRIPTION
The 5765 is a digital amplifier capable of operating at a nominal output power of 50 watts
average. The 5765 is comprised of a 25W Power Amplifier Subassembly, a Power Factor
Corrected (PFC) Front End Module, Peak Detector/Control Board, and a directional coupler.
Combining the latest in GaAs FET amplifier technology and Feed Forward distortion
cancellation, the 5765 delivers an output power of 25 watts (average).
The unit's circuitry is enclosed in a tray assembly designed for mounting in a standard 19"
equipment rack. The unit comes complete with slide rail mounting hardware to allow the tray
to move in and out of the rack for ease of service. The outside dimensions of the tray
assembly are 19" x 30" x 10.25" (WxDxH).
The 5765 is factory calibrated for a front panel LCD display external power meter reading of
100% on the driver transmitter, which represents the rated output power of the unit (unless
otherwise specified).
