Skyworks Solutions, Inc. 2.4 GHz CMOS WLAN RF Front-end Integrated Circuit with PA, LNA with Bypass, and SP3T Switch for WLAN and Bluetooth® Signal Function RFX8422S

Please note: RFX8422S is being discontinued and is not recommended for new designs. The RFX8422S is a fully integrated, single-chip, single-die RF front-end integrated circuit (RFeIC®) that incorporates all the RF functionality needed for dual-mode WLAN and Bluetooth® signal functions including simultaneous WLAN and Bluetooth® signal receive mode. The RFX8422S architecture integrates a high-efficiency high-linearity PA, a directional coupler and output power detector, impedance matching networks, harmonic filters, a LNA with Bypass and an SP3T antenna switch all in a single CMOS device. This RFeIC is designed to be used in the 2.4 GHz band, and can be powered directly from the battery. Combining superior performance, ultra-low power consumption, small form factor, and low cost, RFX8422S is the perfect solution for mobile, handheld, and portable devices with integrated WLAN and Bluetooth® functions. The RFX8422S is assembled in the ultra-compact 2.5 x 2.5 x 0.45 mm 16L QFN package, and requires minimal external components and PCB footprint.
