This is 802.11N Wifi IP core extracted from high volume production chip shipped in Tier 1 handsets, the 802.11 A/B/G/N Baseband/MAC wireless solution operating in a single stream mode for low-power standalone, embedded stations, access points, and Internet of Things (IoT) applications.
This IP core supports both mandatory and optional features of the IEEE 802.11N standard and its corresponding WiFi Alliance certifications. It can also be used in a variety of configurations, including IEEE 802.11b only and IEEE 802.11b/g or IEEEE 802.11b/g/n combinations.
It offers a complete and self-contained Wi-Fi networking solution by harnessing the capacity to host application or offload Wi-Fi networking functions from another application processor. Furthermore, the IP has been designed to achieve the lowest power consumption with a combination of several proprietary techniques for low-power mobile wearable electronics and IoT applications.
This RF transceiver IP is the design database of a WiFi Dual Band RF Transceiver extracted from a 55nm production chip shipped in Tier 1 handsets. The RF Architecture gives the 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.
