SU1238178A1 - Microwave filter - Google Patents

Abstract

The invention relates to microwave technology and can be used in microwave amplifiers and oscillators. The purpose of the invention is to increase the attenuation and reduce the size. The microwave energy supplied to segment 1 of the coaxial line propagates along the periodic structure formed by the ferrite plate plates (FP) 4, metal plates (MP) 5, additional MP 6 connected to the inner and outer, respectively, conductors 3 and 2 segment 1, and the dielectric (D) 7. Sch 5 and additional R 6, which are not homogeneity reflectors, enhance the coupling of the propagating wave with the FP 4, and D 7 with a dielectric constant of € 1, located between MP 5 and additional MP . 6, placed on adjacent OP 4, increases their electrical length. The goal is achieved by introducing additional MP 6 and D 7. .1 Il. C. (@ W 1 6 7 a A b S 4 ISD oo 00 VI 00

Description

112

The invention relates to microwave technology and can be used in amplifiers and microwave generators to prevent communication between individual functional units, as well as to exclude electromagnetic energy into the surrounding space through power inputs and control of packaged hybrid integrated circuits.

The aim of the invention is to increase the attenuation and reduce the size.

The drawing shows the construction of the microwave filter.

The microwave filter contains a length of 1 coaxial line, between the outer and inner conductors 2 and 3 of which are installed perpendicular to them ferrite plates 4, on both sides of each of which are placed metal plates 5 and additional metal plates 6, with metal plates 5 connected to the inner conductor 3, and the additional metal plates 6 - with the outer conductor 2. Between the metal plates 5 and the additional metal plates 6 placed on adjacent ferrite plates 4, are located false insulator 7 with permittivity EG

The microwave filter works as follows.

Microwave energy, - is supplied to the segment 1 of the coaxial line, spread

wounds along the periodic structure formed by ferrite plates 4, metal plates 5, additional metal plates 6 connected respectively to inner and outer conductors 3 and 2, and dielectric 7. Metal plates 5 and additional metal plates 6, are reflective inhomogeneities, amplify the coupling of the propagating wave with the ferrite plates 4. Dielectric 7 increases their electrical length.
