摘要/Abstract:
本文提出了一种用于短距离无线通信的低功耗多频带可配置收发机。该收发机接收模式采用中频载波频率为3MHz的低中频结构,发射模式采用直接上变频结构。在接收和发射模式下该收发机均可于250kHz-2MHz之间配置信号带宽,在MSK调制方式下支持最高通信码率为3Mbps。该收发机采用一个可配置的多带整数分频锁相环频率综合器产生300MHz到1GHz的正交本地震荡。该收发机使用0.18um的CMOS集成电路工艺设计实现。测试结果表明,接收机在400/900MHz下的噪声系数分别为4.9/5.5dB,输入三阶交调截点
A reconfigurable multi-mode multi-band transceiver for low power short-range wireless communication applications is presented. The low intermediate frequency (IF) receiver with 3 MHz IF carrier frequency and the direct-conversion transmitter support reconfigurable signal bandwidths from 250 kHz to 2 MHz and support a highest data rate of 3 Mbps for MSK modulation. An integrated multi-band PLL frequency synthesizer is utilized to provide the quadrature LO signals from about 300 MHz to 1 GHz for the transceiver multi-band application. The transceiver has been implemented in 0.18 um CMOS process. The measurement results show that the receiver achieves the noise figure (NF) and input 3rd order intermodulation point (IIP3) at the maximum gain mode are 4.9/5.5 dB and -19.6/-18.2 dBm in 400/900 MHz band, respectively. The transmitter working in 400/900 MHz band can deliver 10.2/7.3 dBm power to a 50 Ohm load. The transceiver consumes 32.9/35.6 mW in receive mode and 47.4/50.1 mW in transmit mode in 400/900 MHz band respectively.
