A UWB CMOS Transceiver
一个UWB CMOS收发器

       A direct-conversion ultra-wideband (UWB) transceiver for Mode 1 OFDM applications employs three resonant networks and three phase-locked loops. Using a common-gate input stage, the receiver allows direct sharing of the antenna with the transmitter. Designed in 0.13- m CMOS technology, the transceiver provides a total gain of 69–73 dB and a noise figure of 6.5–8.4 dB across three bands, and a TX 1-dB compression point of 10 dBm. The circuit consumes 105 mW from a 1.5-V supply
