150 Watt isolated DC-DC converters for RF power amplifier applications introduced by Murata

MANSFIELD, Mass., 26 Feb. 2013. Murata Power Solutions in Mansfield, Mass., is introducing the PAQ series of 150 Watt isolated DC-DC converters for radio frequency power amplifier applications such as telecommunications infrastructures, CATV systems, satellite communications, RF test, and MRI imaging equipment.

Packaged as an industry-standard open-frame quarter-brick module with through-hole mounting, the power electronics module has a 2:1 input range of 36 to 75 volts DC around a nominal 48-volts DC input.

The single 29.8-volt DC nominal output can be trimmed from 23.83 (-20 percent) to 32.78 (+10 percent) volts DC. This efficient DC-DC converter, typically 92.5 percent, can deliver as much as 5 amps output current from the regulated output.

An optional baseplate is available for use in conduction-cooled designs such as sealed box RF power amplifiers that are often mounted on radio masts. For these applications the converter and baseplate are fixed directly to the host equipment chassis.

Protection features include output over voltage, over current protection, input under voltage, and over temperature shutdown. A remote on-and-off control option offers negative or positive logic input. Input and Output isolation is provided by 2,250-volt DC basic insulation.
