摘要
DSRC在狭窄的通信区域内为道路侧设备和车载设备提供高速无线电连接。本文采用本公司0.8 /spl mu/m SiGe HBT工艺技术，设计制作了一款用于DSRC射频发射机的5.8 GHz上变频混频器，并集成了中频/低频/射频匹配、中频/低频输入平衡器和射频输出平衡器。测量的性能为3.5 dB转换增益，-12.5 dBm输出IP3, 42 dB LO到IF隔离，38 dB LO到RF隔离，3.0 V电源电压下电流消耗为29 mA，制造的混频器芯片尺寸为2.7 mm /spl倍/ 1.6 mm。
A 5.8 GHz up-conversion mixer for DSRC transmitter
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 /spl mu/m 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 /spl times/ 1.6 mm.
