Qorvo QFP4526 and QFP4568 block diagram.
The low-power QFP4526 and high-power QFP4568 bring switches, filters, and amplifiers to Wi-Fi 8 (802.11ax) designs.
Wi-Fi 6 (IEEE 802.11ax) access points, routers, gateways, customer-premise devices, and IoT devices need amplifiers to boost signal power to its final levels. The QFP4526 and QFP4568 front-end modules from Qorvo operate at 3.7 V and 5 V power supplies, respectively. A SPDT switch, filters that remove second and third harmonics as well as reject 2.4 GHz signals in the local area, and a low-noise amplifier (LNA) complete the device.
The table compares specs for the two devices.
