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
