The QPF7551 from Qorvo is a 5 GHz Integrated Front-End Module that is designed for Wi-Fi 6 Home Mesh Networks. It is based on Qorvo’s bandBoost technology that maximizes the capacity and range by boosting band isolation in distributed Wi-Fi 6 systems. The FEM consists of a 5 GHz power amplifier, UNII1- 2a bandBoost BAW filter, SP2T switch, and bypassable low noise amplifier (LNA). It provides a Tx gain of 31 dB and Rx gain of 13 dB with a noise figure of 3.1 dB.
The QPF7551 has integrated die level filtering for 2nd and 3rd harmonics, and 2.4 GHz rejection for DBDC operation on the Rx path. This receiver path matches the optimal technologies to maximize Rx sensitivity through noise figure performance. It requires a DC supply of 5 V and is integrated with a DC power detector for providing a proportional voltage for given output power from the transmit path. The FEM is ideal for access points, wireless routers, residential gateways, customer premise equipment, and IoT applications.
