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 singlechip 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 16lead 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.

Note 1: For normal operation of the RFX8055, VDD must be continuously applied to VDD supply pin.
Note 2: If control voltage can exceed 1.8V, a 1KΩ – 10KΩ series resistor is recommended for the application circuit on each
control line.
Note 3: Thermal measurements were performed on an RFaxis test EVB under typical use conditions. Please contact RFaxis
for details regarding the test conditions and the configuration of the thermal vias on the EVB. Refer to “PCB Land
Pattern” for recommended thermal vias.
