RFX8051B is a highly integrated, single-chip, single-die RFeIC (RF Front-end
NC
12 GND
Integrated Circuit) which incorporates key RF functionality needed for IEEE
802.11a/n/ac WLAN system operating in the 5.15-5.85GHz range. The RFX8051B
architecture integrates a high-efficiency high-linearity power amplifier (PA), a low
RX
11 NC
noise amplifier (LNA) with bypass, the associated matching network, LO rejection,
and harmonic filters all in a CMOS single-chip device.
