Three-stage RF PA

8 April 2015 Analogue, Mixed Signal, LSI

The RFPA5522 is a three-stage power amplifier (PA) designed for 802.11a/n/ac applications. Made by RF Micro Devices, its integrated 50 Ω matching at input and output greatly reduces layout area, bill of materials and manufacturability costs in an end product. The chip is manufactured on an advanced InGaP heterojunction bipolar transistor (HBT) process and is capable of achieving linear powers up to 23 dBm with an error vector magnitude (EVM) below 1,8% while maintaining excellent power added efficiency. The device is provided in a 4 x 4 x 0,9 mm laminate package that meets or exceeds the power requirements of IEEE802.11a/n/ac Wi-Fi systems.
