摘要

提出了一种满足IEEE 802.11p标准掩码c规范的5.9 GHz车载无线通信专用短距离通信(DSRC)发射机，该发射机由可编程增益放大器(PGA)、上变频混频器、驱动放大器和合成器组成。采用无源混频器、推挽本振(LO)缓冲器和互调失真(IMD)消除器实现高线性度和低功耗。该发射机采用CMOS 0.18 μm工艺设计制作。总功耗为1.8 V时的63ma。在1MHz偏移时，合成器的相位噪声为−109.4 dBc/Hz。发射机总噪声系数(NF)为14.2 dB，相邻信道泄漏比(ACLR)为- 53.6 dBc。

A 5.9 GHz DSRC transmitter IC for vehicle wireless communication system

This paper present a 5.9 GHz dedicated short range communication (DSRC) transmitter for wireless vehicular communication that satisfies specification of IEEE 802.11p standard mask c. The proposed transmitter consists of programmable gain amplifier (PGA), up-conversion mixer, drive amplifier, and synthesizer. Passive mixer, push-pull local oscillator (LO) buffer, and intermodulation distortion (IMD) canceller are applied to achieve high linearity and low power consumption. The transmitter is designed and fabricated on CMOS 0.18 μm process. The total power consumption is 63 mA at 1.8 V. A phase noise of synthesizer is −109.4 dBc/Hz at 1MHz offset. The transmitter total noise figure (NF) and adjacent channel leakage ratio (ACLR) are 14.2 dB and − 53.6 dBc, respectively.
