Production Data Sheet
CMOS 5GHz WLAN 802.11a/n/ac RFeIC WITH PA, LNA, AND SPDT
Description
RFX8055 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 systems operating in the 5.1-5.95GHz range. The
RFX8055 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.
RFX8055 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.
RFX8055 is assembled in an ultra-compact low-profile 2.3x2.3x0.4 mm 16-
lead QFN package. With support to direct battery operation, the RFX8055 is
ideal RF front-end solution for implementing 5GHz WLAN in smartphones
and other mobile platforms.
