802.11 N/G/B/A 2.4/5GHz RF Transceiver IP

概述特征请求数据表

This RF transceiver IP is the design data base of a WiFi Dual Band RF Transceiver extracted from a 55nm production chip shipped in Tier 1 handsets.

The RF Architecture gives highest level of integration, and optimized for low power consumption. A single RF LC oscillator PLL provides the quadrature LO signals to the low and high band up and down converters.

The low and high band signals are demodulated by separate RF front-ends. The radio signal from the balanced 2.4 GHz or 5 GHz RF input is amplified by the low band or high band LNA he digital modem implements the OFDM and DSSS/CCK modulation for all frame-formats specified for a single layer/transmitter. The OFDM and DSSS/CCK modulated I/Q signals use a common circuit for digital up-sampling, filtering, quadrature imbalance compensation, LO leakage correction, and digital power scaling.

The RF design incorporates best in class cellular blocker tolerance & transmit emissions in cellular bands. PTA/ePTA with BT.
