摘要

在本文中，我们介绍了一种紧凑型、低功耗、固态外差接收器的最新性能结果，该接收器正在开发中，目标是2.06太赫兹中性氧[OI]线。接收机前端采用亚谐波肖特基二极管混频器，由高输出全肖特基倍频本振(LO)源驱动。乘法器链由一个38 GHz振荡器组成，随后是114 GHz、343 GHz和1.03 THz的级联三倍器，产生~1 mW的本振功率。该接收器的特点是灵敏度在室温和70k之间。给出了额外的数据，证明了接收机在艾伦时间方面的稳定性。

A Compact Schottky Heterodyne Receiver for 2.06 THz Neutral Oxygen [OI]

In this paper we present the latest results on the performance of a compact, low power, solid-state heterodyne receiver that is being developed to target the 2.06 THz neutral oxygen [OI] line. The receiver front end features a subharmonic Schottky diode mixer that is driven by a high output all-Schottky multiplier local oscillator (LO) source. The multiplier chain consists of a 38 GHz oscillator followed by cascaded triplers at 114 GHz, 343 GHz and 1.03 THz to produce ~1 mW of LO power. The receiver is characterized for sensitivity between room temperature and 70 K. Additional data is presented demonstrating the receiver stability in terms of Allan time.
