RFX8050 is a highly integrated, single-chip, single-die RFeIC (RF Front-end
NC
12 GND _{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
RX
11 NC
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.
