RFX8050W Production Data Sheet CMOS 5GHz WLAN 802.11ac RFeIC WITH PA, LNA AND SPDT LEN RXEN GND ANT 16 15 14 13 Description NC 1 12 GND RX 2 11 NC NC VDD 3 10 4 9 5 6 7 8 DET TXEN GND TX NC NC RFX8050W 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 5.15-5.85GHz range. 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.
