Abstract

A transmitter with an output frequency range from 341 to 386 GHz is presented. Power output varies from 0.1 to -15.8 dBm along its operating range, while it remains above -2.9 dBm from 341 to 353 GHz. The high-frequency signal is generated using a wideband push-push voltage-controlled oscillator (VCO) with coarse and fine frequency tuning control, a 3-stage power amplifier, and a frequency doubler. Additionally, a frequency divider is integrated to provide a second low- frequency output for measurement purposes and to enable later the addition of a phase-locked loop (PLL) for the stabilization of the VCO. The obtained frequency tuning range of 12.4% is a record value for silicon-based transmitters above 300 GHz. The total power consumption is 790 mW. The chip is fabricated in a 130nm SiGe BiCMOS technology with fT/fmax = 250/370 GHz.
基于SiGe BiCMOS技术的341-386 GHz宽带发射机
设计了一种输出频率范围为341 ~ 386 GHz的发射机。在其工作范围内,功率输出在0.1到-15.8 dBm之间变化,而在341到353 GHz范围内,功率输出保持在-2.9 dBm以上。高频信号的产生采用宽带推推式压控振荡器(VCO),具有粗、细频率调谐控制,3级功率放大器和倍频器。此外,还集成了一个分频器,为测量目的提供第二个低频输出,并允许稍后添加锁相环(PLL)以稳定压控振荡器。获得的频率调谐范围为12.4%,是300 GHz以上硅基发射机的记录值。总功耗为790mw。该芯片采用130纳米SiGe BiCMOS技术制造,fT/fmax = 250/370 GHz。
