摘要

给出了工作频率为60 GHz的硅锗发射机的仿真结果。超外差发射机基于带有两个上转换级的移动中频架构。发射机包括一个基带至12 GHz图像抑制混频器，一个12至60 GHz吉尔伯特单元混频器，一个无源平衡器和一个功率放大器，其饱和输出功率大于13 dBm。使用连接到4位DAC的3线串行接口可调谐所有偏置电压。片上还有一个频率合成器，为两个混频器提供LO，并将片上24 GHz VCO锁定到外部源。

A 60GHz transmitter in 0.18\mu m Silicon Germanium

Simulated results for a silicon germanium transmitter operating at 60 GHz are presented. The super-heterodyne transmitter is based on a moving IF architecture with two up-conversion stages. The transmitter includes a baseband to 12 GHz image- reject mixer, a 12 to 60 GHz Gilbert-cell mixer, a passive balun and a power amplifier capable of greater than 13 dBm saturated output power. All bias voltages are tuneable using a 3-wire serial interface connected to 4-bit DAC's. Also on-chip is a frequency synthesizer that supplies the LO to both mixers and locks the on-chip 24 GHz VCO to an external source.
