本文提出了一种采用SiGe:C双极实验室技术的240 GHz左右超宽带单片雷达收发器MMIC， fT为240 GHz， fmax为380 GHz。所提出的收发器架构由一个120 GHz基本压控振荡器、两个240 GHz倍频器、一个240 GHz基本下变频混频器、一个四分频级、一个锁相环混频器和两个片上贴片天线组成。完整的收发器架构是完全差分的。该芯片使发射贴片天线的峰值输出功率（EIRP）为-1 dBm，调谐范围为61 GHz。1mhz偏置时的相位噪声在240 GHz时为-84 dBc/Hz（在整个调谐范围内优于-76 dBc/Hz）。240 GHz混频器的模拟噪声值低于17 dB，模拟转换增益优于5 dB，输入参考压缩点为-1.3 dBm。该结果是在单个5v电源的功耗为750 mW的情况下实现的。
This paper presents an ultra-wideband single-chip radar transceiver MMIC around 240 GHz in a SiGe:C bipolar laboratory technology with an fT of 240 GHz and fmax of 380 GHz. The presented transceiver architecture consists of a fundamental 120 GHz VCO, two 240 GHz frequency doublers, a fundamental 240 GHz down-conversion mixer, a divide-by-four stage, a PLL-mixer and two on-chip patch antennas. The complete transceiver architecture is fully differential. The chip facilitates a -1 dBm peak output power (EIRP) at the transmit patch antenna and a tuning range of 61 GHz. The phase noise at 1 MHz offset is -84 dBc/Hz at 240 GHz (and better than -76 dBc/Hz over the full tuning range). The 240 GHz mixer offers a simulated noise figure below 17 dB, a simulated conversion gain of better than 5 dB, and an input refered compression point of -1.3 dBm. The results are achieved with a power consumption of 750 mW from a single 5 V supply.
