1x1 SISO Dual Band 802.11ac Transceiver IP

Wi-Fi Logo

1x1 SISO Dual Band 802.11ac Transceiver IP is a complete front-end optimized for dual band high performance WiFi applications. It is compliant with the IEEE 802.11a/b/g/n/ac standards and designed for manufacturing in the TSMC 28nm HPC process, which makes it suitable for high-end applications like access points and wireless routers. The transceiver architecture is using direct conversion in both transmit and receive mode.

Features

  • Dual band transceiver supporting IEEE 802.11a/n/ac and IEEE 802.11b/g/n
  • Concurrent dual band operation
  • Excellent RF performance providing best in class EVM performance
  • Integrated linear Power Amplifier
  • Reduced bias current with reduced output power, allowing optimized bias conditions for different use cases
  • Integrated receive and transmit switches2
  • Integrated analog channel filters
  • Easy to use with autonomous calibration routines and simple digital baseband interface
  • Internal auxiliary ADC for calibration purposes, RF power and temperature measurements
  • Fractional-N synthesizers with small frequency step size and integrated loop filter
