摘要

提出了一种基于谐振隧道二极管的超低直流功率负差导微波放大器，并首次报道了其噪声系数特性。该放大器具有极低的直流功耗(155 μW)和良好的射频性能，在5.5 GHz时射频增益为8.1 dB，回波损耗大于11 dB，噪声系数为4.5 dB。增益-直流功率比估计为52.2 dB/mW。所获得的增益与直流功率比和噪声系数的优值(FOMs)在相关频段的亚毫瓦低功率单片放大器中是创纪录的。

Negative-differential-conductance RTD amplifier MMIC with record foms of gain-to-dc power ratio and noise figure

An ultralow-dc-power negative-differential-conductance (NDC) microwave amplifier using resonant tunneling diodes (RTDs) is presented and its noise figure characteristic is for the first time reported. The fabricated amplifier exhibits an extremely low dc-power consumption of 155 μW along with good RF performances of an RF gain of 8.1 dB, a return loss of more than 11 dB, and a noise figure of 4.5 dB at 5.5 GHz. The gain-to-dc power ratio was estimated to be 52.2 dB/mW. The figures-of-merit (FOMs) of the achieved gain-to-dc power ratio and noise figure are record for sub-mW low-power monolithic amplifiers at the related frequency band.
