Advanced Data Sheet
5GHZ TRANSMIT / RECEIVE WLAN CMOS RFEIC
Description
RFX5000B is a fully integrated, single-chip, single-die RFeIC (RF Front-end
Integrated Circuit) which incorporates all the RF functionality needed for a
typical IEEE 802.11a/n WLAN system operating in the 4.9-5.85GHz range.
The RFX5000B architecture integrates the PA, LNA, Transmit and Receive
switching circuitry, the associated matching network, and the harmonic filter
all in a CMOS single-chip device. Combining superior performance, high
sensitivity and efficiency, low noise, small form factor, and low cost, the
RFX5000B is the ideal solution for single antenna applications, and the
ideal building block for 802.11n MIMO applications for wireless HDTV and
other high-performance video streaming solutions.
RFX5000B has simple and low-voltage CMOS control logic, and requires
minimal external components including only the external power supply
bypass and the desired band-pass filter for the receive path. A directional
coupler based power detect circuit is also integrated for accurate monitoring
of output power from the PA.
