A FM-UWB transceiver prototype operating in the 7.2 – 7.7 GHz band based upon 3 full-custom ICs is presented. Receiver sensitivity is −85 dBm for a BER of 10−6 at 62.5 kbps. A range of 15 meters is demonstrated under LOS conditions. Power consumption of a SoC version is estimated at 5 mW for the transmitter and 14 mW for the receiver. Subcarrier FDMA multiple access and robustness to narrowband interference...
Two ultra low power wireless concepts are described in this paper. A high data rate receiver demonstrator consisting of LNA, sub-harmonic I/Q mixer and transimpedance IF amplifiers realizes an energy consumption of 1.75 nJ/bit at 10 Mbit/s in the 17 GHz band. A high-band FM-UWB receiver demonstrator, which achieves a measured sensitivity of -84.3 dBm at 100 kbit/s while consuming just 6 mW is also...
