Abstract

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 consumes 16 mW in the Rxand 26 mW in the Tx-mode. The RF-transceiver-chip was integrated with a DSP-unit and mounted on a PCB for wireless indoor localization demonstration. The measured results show a distance measurement precision in the cm-range.
