A Dual-Antenna Phased-Array UWB Transceiver in 0.18- \mu} CMOS

A dual-antenna ultra-wideband (UWB) transceiver in 0.18-mum CMOS for mode-1 OFDM applications employs the techniques of antenna diversity and integrated RF selectivity to improve robustness to interferers. Optimal selectivity in receiver and band flatness in transmitter are achieved by on-chip calib...

More Information
Summary:A dual-antenna ultra-wideband (UWB) transceiver in 0.18-mum CMOS for mode-1 OFDM applications employs the techniques of antenna diversity and integrated RF selectivity to improve robustness to interferers. Optimal selectivity in receiver and band flatness in transmitter are achieved by on-chip calibration of each band. The packaged device achieves an overall noise figure of 4.7 dB, an IIP3 of -0.8 dBm, a TX P1 dB of 3.1 dBm, and an error vector magnitude (EVM) of -27.2 dB for 480 Mb/s. The transmit output spectrum is fully compliant with FCC mask for UWB without any external bandpass filter
