35GHz 到94GHz 范围的毫米波器件难以制作,并具有边界性能。本文讨论毫米波非互易铁氧体侈相器的设计和电弧等离子制作工艺。在开始制作94GHz 移相器之前,已经研究了35GHz 铁氧体移相器的设计和制作技术。4πM_s 为4100高斯的锂铁氧体粉已用于电弧等离子喷涂移相器。对铁氧体粉的处理及其等离子喷涂性能进行了讨论。用插入损耗、带宽和差相移评价器件的性能。铁氧体移相器制作中的任何缺陷,如裂缝或不良的铁氧体介质装配,都会给
Millimeter-wave devices in the 35 GHz to 94 GHz range are difficult to make and have borderline performance. This article discusses the millimeter-wave non-reciprocal ferrite phase shifter design and arc plasma production process. Before starting to make the 94 GHz phase shifter, the design and fabrication techniques for 35 GHz ferrite phase shifters have been studied. 4πM_s is 4100 Gauss lithium ferrite powder has been used for arc plasma spray phase shifter. The treatment of ferrite powder and its plasma spraying performance are discussed. Evaluate device performance with insertion loss, bandwidth, and differential phase shift. Any defects in the ferrite phase shifter fabrication, such as cracks or poor ferrite media assembly, will give
