A implementation of millimeter-wave monolithic isolators by using resonant tunneling devices

本文提出了利用谐振隧道器件实现毫米波单片隔离器的可行性研究。我们明确了利用由两个共振隧道二极管和一个高迁移率晶体管组成的旋转器实现单侧信号传输的准则和频率上限。此外，还发现了无掩模光刻的工艺条件，以获得多台面和电极集成的接触层。

This work presents feasibility studies for an implementation of millimeter-wave monolithic isolators by using resonant tunneling devices. We have clarified a criterion and an upper frequency limit to realize the unilateral signal transmission by using a gyrator, which consists of two resonant tunneling diodes and one high mobility transistor. Moreover, process conditions of mask-less optical lithography have been found to obtain multi-mesa and a contact layer for an electrode to be integrated.
