3mm宽带波导结型隔离器

Broad band 3mm waveguide junction isolators

报道一个具有宽带特性的3mm波导结型隔离器,其性能为插入损耗小于0.8dB,反向隔离大于20dB,绝对带宽为3.5GHz(92.5-96GHz)。对影响器件的性能因素进行了讨论,并指出实验结果似乎与旋转门环行器设计理论不一致。

A 3mm broad band waveguide junction isolator is reported in this paper,it exhibits less than 0.8dB insert loss and more than 20dB isolation in 3.5GHz (92.5-96GHz) bandwidth. Some factors, which can affect the operating properties of the device, are discussed and the discrepancy between experiment results and turnstile circulator theory is pointed out.
