This paper presents the first truly wireless 24-GHz round-trip time-of-flight local positioning frontend with an integrated CMOS transceiver. The transceiver in 130-nm CMOS technology features a novel receiver/transceiver switching concept, which reduces RF losses between the receiver/transmitter and antenna and drastically improves the transmit/receive isolation. The low-power RF transceiver chip...
This paper presents a 130 nm CMOS transceiver for 24 GHz wireless indoor localization. Due to a novel Rx/Tx switching concept RF-losses between receiver/ transmitter and antenna could be reduced and the T/R isolation was drastically improved. The measured transceiver chip achieves an output power and noise figure of >5 dBm and <6 dB, respectively with 2 mm2 total chip size. The complete transceiver...
