The QWX27120 from QuantalRF is a CMOS Wi-Fi 7 Front-End IC that operates from 5150 to 7125 MHz. It is a highly integrated monolithic solution designed for high-performance wireless local area network (WLAN) applications that support all standards up to Wi-Fi 7. This front-end IC is fabricated based on the CMOS SOI process and incorporates a patent-pending power amplifier (PA), a low-loss SP3T switch, and a low-noise amplifier (LNA). The PA offers excellent power efficiency for Wi-Fi 7, while the LNA supports bypass mode. This front-end IC also implements digital pre-distortion (DPD) mitigation in both transmit modes to further improve EVM performance.
In the Tx mode, this front-end IC provides an output power of up to 19 dBm with a gain of 28 dB, while in the Rx mode, it provides a gain of 16.5 dB and has a noise figure of 1.7 dB. It has all the RF ports matched on-chip to 50 Ohms to minimize the external component count and application layout area. This front-end IC requires a DC supply of 3.8 V and consumes 290 mA of current. It is available either in a land grid array package that measures 2 x 2 mm or bare die with Cu pillars for flip-chip assembly. This front-end device is ideal for Wi-Fi 6E/7 systems, smartphones, smart TV, set-top boxes, AR/VR headsets, and other portable battery-operated applications.
