Abstract

This invention relates to microwave radio technology and can be used to switch transmitted power. The purpose of the invention is to provide switching of output channels with preservation of matching. The waveguide switch contains a segment of a rectangular waveguide (OPV) 1, one end of which is an input, a conductive partition (TP) 2 installed parallel to the wide walls of OPV 1 from its other end and separating it into two output channels of the same height. In the output channels, two switching elements 3 are installed on the input side of the TP 2 end. The wide walls of the OPV 1 are stepped with a decrease in the distance between them in the direction of TP 2 to the value on the last stage section ending in the plane of the TP 2 end face heights of output channels and TP 2. This allows the switching of output channels with high matching. 2 Il.

Description

This invention relates to microwave radio technology and can be used to switch transmitted power.

The purpose of the invention is to provide switching of output channels with preservation of matching.

Figure 1 shows the waveguide switch, longitudinal section; figure 2 - section aa in Fig; 1.

The waveguide switch contains a segment of a rectangular waveguide .1, one end of which is an input, a conductive partition 2 installed parallel to the wide walls of the segment of a rectangular waveguide 1 from the side of its other end and dividing it into two output channels of the same output. At the weekend

The channels in the cross section of the end of the conductive partition 2 on the input side have two switching elements 3. The wide walls of the segment of the rectangular waveguide 1 are made stepped with a decrease in the distance between them in the direction to the conductive partition 2. conductive partition 2, equal to the sum of the heights of the output channels and tapes of the conductive partition 2.

Waveguide switch works as follows.

The power supplied to the input is divided in half and fed to the output channels by the conductive partition 2 in the event that the switching elements 3 are open. In this case, the device is matched automatically due to a reduction in its impedance proportional to the height of the output channel and the successive switching of the impedances of these channels. When one of the switching elements 3 is closed, the output channel is short-circuited at the installation site, thereby creating an additional step of the matching step transformer, which ensures that the impedance of the input is matched to the output channel, in which I switch element 1 3 open. In the output channels, additional switching elements can be installed to increase the locking level. The device can be performed on the H-about different waveguide. Switching on switching element 3 in both output channels allows separate switching and placing them in the cross section of the conductor bulkhead 2 on the input side to form an additional step of transformers in their closed state ensures a high level of device matching.
