RFPA5542 is a three-stage power amplifier (PA) designed for 802.11a/n/ac applications. It integrates 50Ω matching at both the input and output, significantly reducing the layout area, bill of materials, and manufacturability costs in customer applications. The PA has been optimized to minimize the required external components while maintaining linear performance. RFPA5542 is manufactured on the advanced InGaP heterojunction bipolar transistor (HBT) process and can achieve up to 23dBm linear power with an EVM of less than 1.8%, while maintaining excellent power increase efficiency. RFPA5542 is packaged in a 4.0mm x 4.0mm x 0.90mm format, meeting or exceeding the power requirements of IEEE802.11a/n/ac WiFi RF systems.
