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 5.15-5.85GHz 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.

Note 1: For normal operation of the RFX8050, VDD must be continuously applied to all VDD supply pins.
Note 2: If control voltage can exceed 1.8V, a 1KΩ – 10KΩ series resistor is recommended for the application
circuit on each control line.
