802.11 AC RF IP



This dual band RF transceiver IP is a complete radio front-end, optimized for IEEE 802.11a/b/g/n/ac SoC implementation, based on the industry’s proven direct conversion transceiver architecture. The RF transceiver IP has fully integrated power amplifiers along with the capability of various commercial external FEM support. RF IO ports are single-ended and a fractional-N synthesizer while the power amplifiers and LDOs are fully integrated for minimum BOM and PIN counts.

The IP supports various radio calibration functions such as PAPD, TRX IQ mismatch calibration, LO feedthrough calibration, DC offset cancellation, fast AGC, VCO calibration, VCO temperature variation compensation, bias calibration, LPF corner frequency compensation, battery monitoring, and temperature monitoring.

The internal, digitally controlled gain stages at the RF and BB levels provide both low noise figure and large dynamic range for the receiver. In addition, the transmitter has more than 30dB gain range, which provides a wide output power range. The cutoff frequency of the baseband filters are calibrated with an internal RC compensation scheme while the low pass filter supports modulation bandwidths up to 80MHz. A crystal oscillator, which is connected to a low cost external crystal, is also integrated. The SPI interface controls most of the transceiver functions.
