The RFX8050W architecture integrates a high-efficiency high-linearity power amplifier (PA), low noise amplifier (LNA) with bypass, the associated matching network, LO rejection, and harmonic filters all in a CMOS single-chip device. RFX8050W 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. RFX8050W is assembled in an ultra-compact, ultra-thin 2.5x2.5x0.4mm 16-lead QFN package. With support to direct battery operation, the RFX8050W is ideal RF front-end solution for implementing 5GHz WLAN in smartphones and many other mobile platforms.
