Due to high output power of 150W, new DC-DC Converters address the needs of micro cell transceivers and indoor Wi-Fi installations.
Latest from Murata is the new PAQ series of 150W isolated DC-DC converters. Packaged as an industry-standard open-frame quarter-brick module with through-hole mounting, the converter has a 2:1 input range of 36 – 75VDC around a nominal 48VDC input. The single 29.8VDC nominal output can be trimmed from 23.83VDC (-20 per cent) to 32.78VDC (+10 per cent) in order to accommodate an application’s specific voltage requirements.
This highly-efficient DC-DC converter, typically 92.5 per cent, can deliver up to 5A 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 that are often mounted on radio masts. For these applications the converter and base plate are fixed directly to the host equipment chassis. In this way the operation of end-equipment is efficiently maintained despite being situated in a potentially demanding physical environment. The high efficiency of the PAQ converter greatly assists in reducing operating costs due to less waste power being generated and helps maintain the unit’s reliability.
The PAQ is particularly suitable for use in a broad range of radio frequency power amplifier applications such as telecommunications infrastructures, CATV systems, satellite communications, RF test and MRI imaging equipment. With its 150W power output rating, the PAQ series is also ideal for the latest generation of micro cell transceivers and indoor Wi-Fi installations, says the company.
