Abstract :
DSRC 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 up-conversion mixer for DSRC RF transmitter is designed and fabricated using our 0.8 μm SiGe HBT process technology and IF/LO/RF matching, IF/LO input baluns and RF output balun are all integrated on chip. The measured performance is 3.5 dB conversion gain, -12.5 dBm output IP3, 42 dB LO to IF isolation, 38 dB LO to RF isolation, current consumption of 29 mA for 3.0 V supply voltage and the chip size of fabricated mixer is 2.7 mm × 1.6 mm.
