RFMW Offers 5GHz Wi-Fi Integrated PA Modules
RFMW, Ltd. announces design and sales support for two new power amplifier modules supporting 5GHz Wi-Fi enabled CPEs, routers, pico cells and femto cells. The Qorvo RFPA5522 supports applications from 5.18 to 5.925GHz with bias configurable to 5V or 3.3V operation. The Qorvo RFPA5542 extends operation from 4.9 to 5.925GHz and is optimized for the least number of external components on compatible reference designs. Both PA modules offer 33dB of gain from three stages of internal amplification and integrate an internal regulator. The RFPA5522 and RFPA5542 dynamic EVM power output is 23dBm at 5V in 802.11ac applications and measures 1.8%. These PA modules offer best in class efficiency drawing 285mA from a 5V supply as 23dBm. Both the RFPA5522 and RFPA5542 are packaged as 4x4mm QFNs.
