RFX8055 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 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.
