QPF4659-QORVO

The Qorvo QPF4659 is an integrated front-end module (FEM) designed for Wi-Fi 7 (802.11be) systems. The compact form factor and integrated matching minimize the layout area in the application.

Performance focuses on optimizing the PA for a 5V supply voltage to save power while maintaining linear output power and leading throughput. This is achieved over a wide bandwidth in all channels from UNII5-8 (5.9 to 7.1 GHz), integrating chip-scale filtering for second and third harmonics, and 2.4 GHz rejection for DBDC operation. A coupler with RF output and a wide-range, constant-slope voltage logarithmic power detector are used for application feedback.

The QPF4659 integrates a 6 GHz power amplifier (PA), single-pole double-throw switch (SP2T), and bypass low-noise amplifier (LNA) into a single device.
