1 2 3 4 RFX8055 Production Data Sheet CMOS 5GHz WLAN 802.11a/n/ac RFeIC WITH PA, LNA, AND SPDT Description LNA EN NC GND ANT RFX8055 is a highly integrated, single-chip, single-die RFeIC (RF Front-end Integrated Circuit) which incorporates key RF functionality needed for IEEE 16 15 14 13 802.11a/n/ac WLAN systems operating in the 5.1-5.95GHz range. The GND 12 GND 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. RX 11 NC RFX8055 has simple and low-voltage CMOS control logic, and requires minimal external components. A directional coupler based power detect GND 10 NC 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- VDD 9 VMODE lead QFN package. With support to direct battery operation, the RFX8055 is 5 6 7 8 ideal RF front-end solution for implementing 5GHz WLAN in smartphones and other mobile platforms.
