Radio

  • On-chip baluns for single-ended RF input and output
  • No external trimming required in production
  • Low output spurii and strong receive blocking performance against cellular bands
allows for good coexistence with cellular radios
  • Front-end control logic can be programmed to support common 802.11 only and 802.11
+ Bluetooth RF front-end configurations
  • Support for antenna diversity selection

Transmitter

  • Support for power compensation of external PA to produce stable transmit power across temperature
  • Digital predistortion can be used to compensate for non-linearities in external PA
  • Control of transmit gain settings on a per-packet basis allows transmit power to be optimised
for each modulation scheme

Receiver

  • Fast AGC and wide dynamic range allow for excellent robustness against fading

Frequency Synthesiser

  • Fully integrated fractional-N synthesiser
  • Low phase noise and fast switching time
  • Supports all 802.11b/g/n (20MHz) channel frequencies

Frequency Reference

  • Support for common cellular reference frequencies
  • On-chip crystal driver
  • Digital trimming of crystal allows use of less-tightly toleranced crystals
  • Internal low-power clock eliminates requirement foran additional frequency references

Auxiliary Features

  • Four 10-bit ADCs/DACs used for internal calibration. These can also be used to provide
a bias voltage or measure the output power of an external PA.

Modem
