摘要：

This article presents a ultra-wideband (UWB)-based wireless transceiver (TRX) in a reconfigurable frequency-division duplexing (FDD) wireless network for short-range multicast applications. The TRX operates at the 7-10-GHz band, adopts a digital-process-friendly architecture, and delivers up to 2-Gb/s data rate in 500-MHz channel bandwidth. The measured power consumption is 19.8 mW at the 8-GHz channel, resulting in a best-in-class energy efficiency of 9.9 pJ/b for sub-10-GHz wireless TRXs. The TRX outputs -5.5-dBm power and achieves -67.5-dBm sensitivity at 1 Gb/s. Having a coherent TRX architecture, it can tolerate self-interference during FDD operation with 1-dB receiver de-sensitization and close-in -26-dBm Wi-Fi blockers with 3-dB de-sensitization.
