A fully integrated 3-band OFDM UWB transceiver in 0.25/spl mu/m SiGe BiCMOS

A fully integrated transceiver for 3-band OFDM UWB is presented. It has been implemented in a 0.25mum SiGe BiCMOS process, and has a die area of less than 4mm2. The power consumption is 47mA, 43mA, and 27mA at 2.7V supply for receiver, transmitter, and synthesizer respectively. The chip features DC offset cancellation, a loop-back test mode, a single input/output pin for antenna connection, a 1GHz baseband clock output and is robust against interferers from cellular and ISM bands. The measured EVM is 8%, while the overall NF is 4.5dB and the iIP3 is -6dBm
