RFX8050 is a highly integrated, single-chip, single-die RFeIC (RF Front-end Integrated Circuit) which incorporates key RF functionality needed for IEEE 802.11a/n/ac WLAN system operating in the 4.9-5.85GHz range. The RFX8050 architecture integrates a high-efficiency high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, LO rejection, and harmonic filters all in a CMOS single-chip device.

RFX8050 has simple and low-voltage CMOS control logic, and requires minimal external components. A directional coupler based power detect circuit is also integrated for accurate monitoring of output power from the PA.

RFX8050 is assembled in an ultra-compact low-profile 2.5x2.5x0.45 mm 16-lead QFN package. With support to direct battery operation, the RFX8050 is ideal RF front-end solution for implementing 5GHz WLAN in smartphones and other mobile platforms.

Please note: RFX8050 is being discontinued and is not recommended for new designs.
