Abstract :
We report a novel harmonic LOG based direct conversion RF transceiver for 802.11n radio. This multi-comm transceiver consists of Bluetooth SoC and WiFi, it includes 19-24GHz VCO, integrated front-end including WiFi T/R and WiFi-BT switches. Fabricated in 90nm digital CMOS technology, this IC consumes 422/560mW (Rx/Tx 802.11n 300/150Mbps), 110mW in BT mode, with an area of approx 19mm2. A peak saturated power of 24/9dBm is achieved at antenna in WiFi/BT mode.
