Abstract :
DSRC (dedicated short range communication) provides high speed radio link between road side equipment and on-board equipment within the narrow communication area. In this paper, a 5.8 GHz MMIC down-conversion mixer for DSRC receiver is designed and fabricated using SiGe BiCMOS process technology. RF/LO matching circuits, active-based RF/LO input balun circuits, and active-based IF output balun circuit are all integrated on chip with mixer core circuit. The measured results of the fabricated mixer show conversion gain of 5.5 dB, LO to RF isolation of 44 dB, and LO to IF isolation of 40 dB, IIP3 of 1.8 dBm. The chip size of the fabricated mixer is 1.9 mm times 1.2 mm
