Abstract

The utility model relates to radio engineering and can be used in switches, phase shifters, attenuators, transceiver paths and other waveguide microwave devices. The essence of the utility model is that a waveguide switch containing a waveguide, a diaphragm and eight pin diodes, in which two H-shaped slots, two copper electrodes and four copper grids are introduced, allows you to adjust the operating frequency without disassembling the device and mechanical refinement diaphragm. The adjustment of the operating frequency occurs due to the bending of the copper electrodes, while due to the use of copper grids, there is no mechanical effect on the pin diodes. The technical result consists in the possibility of adjusting the operating frequency of the waveguide switch without disassembling and mechanically refining the diaphragm.

Description

The utility model relates to radio engineering and can be used in switches, phase shifters, attenuators, transceiver paths and other waveguide microwave devices.

A waveguide switch was chosen as a prototype (RF patent No. 56721 2005, IPC H01R 1/15, publ. 10.09.2006)

Device - the prototype contains, including a waveguide, diaphragm and p-i-n-diodes.

Due to the fact that p-i-n-diodes have irregularities in their characteristics, this can cause a change in the operating frequency of the waveguide switch. At the same time, the mechanical refinement of the diaphragm, which is part of the prototype, in order to achieve a given operating frequency, requires a complete disassembly of the device, refinement and subsequent assembly, while additional improvements may be required in cases where the specified operating frequency has not been set. At the same time, it remains possible to completely disrupt the operation of the waveguide switch in case of errors at the stage of mechanical refinement (too large slot length or geometry mismatch).

The disadvantage of the prototype device is the impossibility of adjusting the operating frequency without mechanical refinement of the diaphragm.

The problem to be solved is the possibility of adjusting the operating frequency of the waveguide switch without disassembling and mechanically refining the diaphragm.

This result is achieved by introducing two H-shaped slots (NOSH), two copper electrodes (ME), four copper grids (MC) into the design.

The essence of the proposed device is illustrated by the figure (figure 1), where the following designations are accepted:

1 - waveguide (VD);

2 - diaphragm (DF);

3 - the first H-shaped slot (NOSH);

4 - second NOSCH;

5 - the first copper electrode (ME);

6 - second ME;

7 - the first copper grid (MS);

8 - second MS;

9 - third MS;

10 - fourth MS;

11 - the first p-i-n-diode (PD);

12 - second PD;

13 - third PD;

14 - fourth PD;

15 - fifth PD;

16 - sixth PD;

17 - seventh PD;

18 - the eighth PD.

The first, second, third and fourth PDs are installed on both sides of the first NOSCH on the DF surface, and the fifth, sixth, seventh and eighth PDs are installed on both sides of the second NOSCH on the DF surface, respectively (Fig. 1). All eight PDs are cathode-connected to the DF. In this case, every two PDs are connected to the MS anode. The first and second TDs are connected to the first MS, the third and fourth TDs are connected to the second MS, the fifth and sixth TDs are connected to the third MS, and the seventh and eighth TDs are connected to the fourth MS, respectively. Two MEs are used to manage groups of four APs in each of the two NOSs. The first ME is installed in the first NOSH and connected to the first and second MS, and the second ME is installed in the second NOSH and connected to the third and fourth MS, respectively. To control eight PDs, a blocking voltage is applied to the first and second MEs. In this case, each of the eight PDs can introduce irregularities in the frequency response of the waveguide switch. To adjust the frequency response, a mechanical pusher * can be introduced into each of the two NOSCHs (* - shown conditionally) giving a bend to the first and second ME, the specified operating frequency is achieved (Fig. 2). In this case, when exposed to the first and second MEs, the first, second, third, and fourth MSs can be deformed without exerting a mechanical effect on all eight PDs. If necessary, one of the two MEs can be bent (Fig. 3). The first and second ME are located perpendicular to the field vector E, the unevenness formed by the bending of the first and second ME allows you to change the wave resistance of the waveguide switch in a given frequency range. Thus, it is possible to compensate for the effect of unevenness of each of the eight PDs on the operating frequency, thereby the waveguide switch can be tuned to the operating frequency without disassembly and mechanical modification.

The specified technical result is achieved by a combination of distinctive features, namely by introducing two H-shaped slots, two copper electrodes and four copper grids into the design.

The presented description of the claimed device allows, using known materials, technologies, purchased products and components, to manufacture it industrially and use it in switches, phase shifters, attenuators, transceiver paths and other waveguide microwave devices.
