Intel Develops CMOS Radio Supporting All Flavors of 802.11

Intel has developed a prototype of an all-CMOS direct conversion dual-band radio transceiver capable of supporting every current Wi-Fi standard (802.11a, b and g), as well as the projected requirements of 802.11n. The device integrates a 5GHz CMOS power amplifier that meets all the spectral purity and non-interference requirements from the FCC, while frequency planning techniques minimize interference caused by the on-die amplifier. To achieve these results, Intel researchers developed a new calibration scheme for the transceiver to achieve high volume manufacturability. Separating receiver and transmitter effects has proven to be difficult in the past, but Intel said its scheme is easy to implement and correctly separates the effects, improving yields and lowering the cost of these radios.
