Three-stage power amplifiers for access point, gateway applications
Richardson RFPD's RFPA5522 and RFPA5542 Wi-Fi-integrated PA modules from Qorvo are three-stage power amplifiers designed for wireless access points and gateways and routers.
Richardson RFPD's RFPA5522 and RFPA5542 Wi-Fi-integrated PA modules from Qorvo are three-stage power amplifiers designed for 802.11a/n/ac applications. The PA modules are designed for wireless access points and gateways, routers, set-top boxes, and picocell/femtocell applications. The integrated input and output 50Ω match reduces the layout area, bill of materials and manufacturability cost. The devices are manufactured on an advanced InGaP heterojunction bipolar transistor (HBT) process and are capable of achieving linear powers up to +23 dBm with an EVM <1.8% while maintaining power added efficiency. The RFPA5522 offers an extended operating frequency of 4.900 GHz to 5.925 GHz, at either a 3.3V or 5V bias. The RFPA5542 also offers an extended operating frequency of 4.900 GHz to 5.925 GHz, at 5V bias, and is designed to minimize the required external components to maintain linear performance.
