QWX23105

2.4 GHz Wi-Fi 7 Front End Module
The QuantalRF QWX23105 is a highly integrated single front-end IC designed for high performance Wireless Local Area Network (WLAN) and Bluetooth applications supporting all standards up to Wi-Fi 7. It features a patent pending PA architecture providing superior linearity, a low loss single-pole, double-throw (SPDT) switch and an LNA.
  • Support for Digital Pre-Distortion (DPD) is implemented in transmit modes for a further improved EVM performance.
  • All RF ports are matched on-chip to 50 ohms to minimize the external components and application layout area.
  • The QWX23105 is fabricated as a single die in CMOS RF-SOI technology.
