A 0.18/spl mu/m CMOS Dual-Band UWB Transceiver

A dual-band transceiver able to work on both UWB low band (3 to 5GHz) and high band (7 to 9GHz) is presented. A method of DSB upconversion in TX, and SSB downconversion and detection in RX is proposed to achieve high data rate non-coherent communication. Realized in 0.18 μm CMOS, the RX achieves an NF of 9.4dB, an IIP3 of -10.3dBm, and a sensitivity of -76dBm. It can attain a transmission rate up to 800Mb/s and draw 55mA and 76mA from a 1.8V supply in TX and RX, respectively.
