Problems solved by technology

This will significantly increase the cost of handling and assembling multi-junction stripline circulators
Also, each node in a junction-type stripline circulator has a corresponding component set, which may allow non-uniform tolerances to accumulate in the component set, which may adversely affect the performance of the stripline circulator

Embodiment Construction

[0021] US Provisional Patent Application No. 60 / 311,709, filed August 10, 2001, is incorporated herein by reference.

[0022] The junction-type stripline circulator has enhanced electrical and mechanical properties, and reduces manufacturing costs. In the junction-type stripline circulator, oval-shaped permanent magnets and oblong ferrite components are used in multiple junctions of the circulator in order to eliminate uneven tolerance build-up and uneven Permittivity dielectrics, the accumulation of this non-uniform tolerance and non-uniform dielectric constant dielectrics can degrade the mechanical and electrical performance of the device. Furthermore, by providing elliptical permanent magnets and oblong ferrite components in a multi-junction stripline circulator, the overall part count and overall assembly time of the device can be reduced, thereby reducing inventory and manufacturing costs.

Abstract

A compact multi-element cascade cyclic energy transferring device is provided in which electrical and mechanical performance is enhanced while handling and assembly costs are reduced. The circulator includes a plurality of junctions connected in cascade to provide a plurality of non-reciprocal transmission path between signal ports on a network, and a metal housing with a cover in which the junctions are disposed. The plurality of junctions includes an oval permanent magnet, a multi-ferrite component including two oblong ferrite elements, a dielectric constant medium disposed between the ferrite elements, and a plurality of conductor portions sandwiched between the ferrite elements. By configuring the multi-element cascade circulator to include the oval permanent magnet and the oblong ferrite component that are employed by more than one junction of the circulator, the multi-element cascade circulator achieves enhanced performance with reduced inventory and manufacturing costs.

Description

technical field [0001] The present invention relates generally to radio frequency and microwave circulators, and more particularly to junction-type stripline circulators (junction-type stripline circulators), which can improve mechanical and electrical performance while reducing manufacturing cost. Background technique [0002] This application claims priority from US Provisional Patent Application No. 60 / 311,709, filed August 10, 2001, and entitled COMPACT MULTI-ELEMENT CASCADE CIRCULATOR. [0003] Known radio frequency (RF) and microwave circulators utilize a DC bias magnetic field generated in ferrite material surrounding conductors to provide at least one non-reversible transmission path between network signal ports. A common node-type stripline circulator includes at least one node that forms an interface between signal ports. Each junction of a junction-type stripline circulator typically includes two (2) permanent magnets, two (2) ground plane sections disposed betw...
