摘要

提出了一种用于24ghz室内无线定位的130nm CMOS收发器。由于一种新颖的Rx/Tx切换概念，可以减少接收机/发射机和天线之间的射频损耗，并大大提高了T/R隔离度。在芯片总尺寸为2 mm2的情况下，所测收发器芯片的输出功率和噪声系数分别为5dbm和6db。完整的收发器在rxx模式下消耗16mw，在tx模式下消耗26mw。射频收发芯片与dsp单元集成，并安装在PCB上，用于无线室内定位演示。测量结果表明，距离测量精度在厘米级。

24 GHz CMOS transceiver with novel T/R switching concept for indoor localization

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.
