Description
RFX8053 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 5.15-5.825GHz range. The
RFX8053 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.
RFX8053 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.
RFX8053 is assembled in an ultra-compact low-profile 2.5x2.5x0.45 mm(Max)
16-lead QFN package. With support to direct battery operation, the RFX8053 is
ideal RF front-end solution for implementing 5GHz WLAN in smartphones and
other mobile platforms.
