RFX8051

CMOS 5GHz WLAN 802.11ac RFeIC WITH PA, LNA AND SPDT

Please note: RFX8051 is being discontinued and is not recommended for new designs.

RFX8051 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 RFX8051 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.

RFX8051 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.

RFX8051 is assembled in an ultra-compact low-profile 3.0x3.0x0.55 mm 16-lead QFN package, and is the ideal RF front-end solution for implementing 5GHz WLAN in smartphones and other platforms.
