A 5.8 GHz Adaptive CMOS Image Rejection Mixer for DSRC Transceiver

This paper presents an Image Rejection Mixer (IRM) for 5.8 GHz Dedicated Short Range Communication (DSRC) Receiver. The proposed IRM operates with both of the Intermediate Frequencies (IF) equal to 5 MHz and 10 MHz which is suitable for the regions which their standard IF is equal to 5 MHz or 10 MHz...

Summary:This paper presents an Image Rejection Mixer (IRM) for 5.8 GHz Dedicated Short Range Communication (DSRC) Receiver. The proposed IRM operates with both of the Intermediate Frequencies (IF) equal to 5 MHz and 10 MHz which is suitable for the regions which their standard IF is equal to 5 MHz or 10 MHz. The proposed mixer is implemented with by image rejection function through a passive RC polyphaser filter. The proposed IRM has a conversion gain up to 7.1 dB, an image rejection ratio (IRR) which exceeds 24.4 dB at both of the IFs equal to 5 MHz and 10 MHz, and its output 1-dB compression point and third-order intercept point are -12.3 dBm and -2.9dBm respectively. The proposed mixer is designed in 130 nm CMOS process and its power consumption is 84 μW.
