摘要

利用微波注入可以提高热电子测热计混合器的稳定性。在本文中，我们报告了这种方法的改进。我们引入了一个微芯片控制器来促进稳定方案的实现，并证明了反馈回路有效地抑制了HEB偏置电流中的漂移，从而提高了接收机的稳定性。混合器中频输出功率的测量艾伦时间增加到> 10 s。

Microwave stabilization of HEB mixer by a microchip controller

The stability of a Hot Electron Bolometer (HEB) mixer can be improved by the use of microwave injection. In this article we report a refinement of this approach. We introduce a microchip controller to facilitate the implementation of the stabilization scheme, and demonstrate that the feedback loop effectively suppresses drifts in the HEB bias current, leading to an improvement in the receiver stability. The measured Allan time of the mixer's IF output power is increased to > 10 s.
