Embodiment Construction

[0022] In order to make the technical solutions and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The first embodiment of the present invention provides a ferrite switch assembly cascaded feeder network, such as figure 1 As shown, the network does not necessarily have to be a rectangle. In the figure, a rectangle is taken as an example, including: printed circuit board wire 1, insulating substrate 2, microwave absorbing material 3, and metal cavity 4;

[0024] Wherein, the microwave absorbing material 3 is arranged on the metal cavity 4;

[0025] The insulating substrate 2 is arranged on the microwave absorbing material 3;

[0026] The printed circuit board wire 1 is embedded in the surface of the insulating substrate 2 away from the microwave absorbing material 3;

[0027] The network described above constitutes a "microstrip l...

Abstract

One embodiment of the invention discloses a ferrite switch assembly cascade feed network and a forming method thereof, the ferrite switch assembly cascade feed network comprises a printed board wire,an insulating substrate, a microwave absorbing material and a metal cavity, the microwave absorbing material is arranged on the metal cavity; the insulating base material is arranged on the microwaveabsorbing material; and the printed board wire is embedded into the surface, far away from the microwave absorbing material, of the insulating base material. By absorbing the microwave signals coupledin the cascade feed network, the high isolation of the ferrite switch assembly is improved, and the isolation performance of the ferrite switch assembly is improved.

Description

technical field [0001] The invention relates to the field of cascaded feeder networks, and more particularly, to a cascaded feeder network of ferrite switch components and a forming method thereof. Background technique [0002] Ferrite switches have the function of changing the transmission channel of microwave signals, and are currently widely used in ground, airborne and satellite radar fields. With the development of science and technology, the user's demand for ferrite devices tends to be multi-functional, combined, miniaturized and lightweight. Therefore, electronically controlled ferrite components appear, that is, multiple ferrite components with the same or different functions The ferrite components are combined to achieve different functions of the ferrite components through electrical control. The ferrite switch assembly is mainly composed of microwave transmission line cavity, ferrite material, magnetized coil and drive feed network, etc., wherein the ferrite mat...
