2013-02-27 150W DC-DC Converter Developed for RF Power Amplifier Applications

The new PAQ series is a fully isolated DC-DC converter packaged as an industry standard open-frame quarter brick module with through-hole mounting. The converter has a 2:1 input range of 36-75 VDC around a nominal 48 VDC input. The single 29.8 VDC nominal output can be trimmed from 23.83 to 32.78 VDC (-20% to +10%) in order to accommodate the application's specific voltage requirements.

This highly efficient DC-DC converter, typically 92.5%, can deliver up to 5 Amps output current from the fully regulated output. An optional base plate is available for use in conduction-cooled designs such as sealed box RF power amplifiers - often mounted on radio masts. The high efficiency of the PAQ converter helps maintain the the unit's reliability as well as greatly assisting in the reduction of operating costs.
