QWX27115

5-7 GHz Edge AI Wi-Fi CMOS DPD-Efficient Linear FEM
The QuantalRF QWX27115 is a highly integrated monolithic DPD-Efficient Linear front-end module designed for Edge AI Wi-Fi devices such as AI/XR glasses, cameras, drones and robots, supporting all WLAN standards up to Wi-Fi 8. It features a patent-pending PA architecture providing superior linearity across all power modes, a low-loss single-pole, triple-throw (SP3T) switch and an LNA.
  • Linearity is optimized for Digital Pre-Distortion (DPD) for further improved EVM performance across all modulation classes.
  • All RF ports are matched on-chip to 50 ohms to minimize external components and application layout area, keeping the RF front end compact in space-constrained Edge AI designs.
  • The QWX27115 is fabricated as a monolithic die in CMOS SOI technology.
