500W quarter brick DC-DC module supports GaN power amplifiers

Artesyn Embedded Power has unveiled its newest dc-dc converter module focused at Gallium Nitride (GaN) radio frequency (RF) power amplifier (PA) applications, the 500W AGQ500 series.

Housed in the industry standard quarter-brick format, the AGQ500 series offers greater than 95 percent typical efficiency and a wide input range of 36 to 75 volts. The 50-volt nominal output model (AGQ500-48S50) is designed to support the growing use of GaN technology used in high power wireless base station (BTS) deployments. This 50 V model can deliver up to 10.A output current.

An aluminum baseplate structure gives AGQ500 series modules excellent thermal performance. The model can operate between minus 40 and plus 850Celsius ambient temperature and can continue to operate at full power up to 1000Celsius baseplate temperature, all without air cooling.

Artesyn’s AGQ500 series dc-dc converter modules offer a wide trim range of 25 to 57 V for the nominal 50 V output version.

Other features include remote enable, remote output sense and trim with protection features such as input under voltage lockout, output over current protection, output over voltage protection, and over temperature protection. No minimum load requirement helps to increase reliability and contributes to a mean time between failure (MTBF) of 1.5 million hours (calculated according to Telcordia SR-332-2006) and is IEC62368 compliant.
