QWX27105
5-7 GHz Wi-Fi 7 Front End Module
The QuantalRF QWX27105 is a highly integrated monolithic front-end IC designed for high performance Wireless Local Area Network (WLAN) applications supporting all standards up to Wi-Fi 7. It features a patent pending PA architecture providing superior power efficiency, a low loss single-pole, triple-throw (SP3T) switch and an LNA.
Support for Digital Pre-Distortion (DPD) is implemented in all transmit modes for further improved EVM performance.
All RF ports are matched on-chip to 50 ohms to minimize the external components and application layout area.
The QWX27105 is fabricated as a monolithic die in CMOS SOI technology.
