Abstract

The invention can be used in the manufacture of radio equipment and provides an increase in the manufacturing accuracy of a millimeter-wave waveguide device. In a metal plate (MP) 1, the thickness of which is equal to one of the dimensions of the waveguide channel (VC), sample 2 is cut in the form of a through hole, forming two opposite walls of the VC. The values of this plane, passing through the beginning and end of the VC, intersect MP 1 to its edges, forming process jumpers 3.

Description

The invention relates to the manufacture of devices for radio equipment, and specifically to methods specifically designed for the manufacture of full-flowing devices, and can be used for the manufacture of microwave waveguide devices of the millimeter wavelength range.

The aim of the invention is to improve the manufacturing accuracy of a millimeter-wave waveguide device.

The drawing shows a waveguide device implemented by this method before removing allowances for technological jumpers along the planes passing through the beginning and end of the waveguide channel.

The waveguide device contains the first metal plate 1, in which i made a sample 2, forming two opposite walls of the waveguide channel, the beginning and end of which are remote from the edges of the metal plate 1 for the width of the technological bridge 3 and second and the third metal plates 4 and 5 respectively

consequently, they form two other walls to one of the other walls of the waveguide waveguide channel.

Waveguide Fabrication

The process is as follows.

In a metal plate 1, the thickness of which is equal to one of the dimensions of the waveguide channel, a sample 2, which is at the specified TOL1CIN selection of the metal plate, is cut out on an electric spark machine with a numerical program control of a non-profiled electrode (wire). 1 through hole forming two opposite walls of the waveguide channel. In this plane, passing through the beginning and end of the waveguide channel, intersect the metal 40

In order to increase the accuracy of the waveguide device of the millimeter range, the first metal plate has a thickness equal to one of the dimensions of the waveguide channel, the planes passing through the beginning and the end of the waveguide channel intersect the first metal plate, A third metal plate is attached to the opposite surface of the first metal plate, forming the second of the other walls of the waveguide channels; metal plates are cut along the planes passing ithout the beginning and end of the waveguide channel.

Cus Plate 1, i.e. Technological jumpers are formed up to its edges, 3. Next, metal plates 4 and 5 are installed and fixed on opposite surfaces of the metal plate 1, for example, by diffusion welding, then the metal plates 1, 4 and 5 are cut, for example, by milling with subsequent finishing on planes passing through the beginning and end of the waveguide channel, i.e.

technological jumpers 3 are removed. I

In the manufacture of a multilayer waveguide device with a large number of metal plates, their relative position during assembly is fixed-i-r by common base planes.
