Description

Technical Field

[0001] The utility model belongs to the technical field of microwave electronics, and in particular relates to a multi-channel sliding waveguide switch. Background Art

[0002] Waveguide switches are commonly used devices in microwave electronic equipment. Their function is to select microwave channels on demand and achieve high-quality signal transmission. Compared with other microwave switches, electromechanical microwave waveguide switches have the characteristics of low standing wave, small insertion loss, and large power capacity. According to the driving mode, they can be divided into electric waveguide switches and manual waveguide switches. Applicable waveguide types include rectangular waveguides and double-ridge waveguides. They have been widely used in radar, electronic countermeasures and other systems.

[0003] Most of the existing waveguide switches, whether manual or electric, can only switch two channels of microwave signals. The commonly used waveguide switch switches channels by rotating the knob 90°. During the rotation, the waveguide port is aligned in the X and Y axes. If one direction of the waveguide port cannot be aligned, it will cause the microwave signal to be "reflected" and the standing wave to be poor. The rotary waveguide switch is structurally composed of a drive motor and a microwave system. The microwave system consists of a microwave rotor and a microwave stator.

[0004] Traditional waveguide switches can only realize the conduction and cutoff of microwave signals in two designated adjacent channels, and there are only two channels. The microwave stator and microwave rotor must have relative motion, and there is a gap between them. When the microwave rotor rotates, it is very likely that the waveguide opening of the microwave rotor will not match the waveguide opening of the microwave stator, resulting in microwave signal loss. This requires very high structural processing accuracy, which increases costs. Utility Model Content

[0034] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] Ginseng Figures 1 to 17 As shown, this embodiment provides a multi-channel sliding waveguide switch, including a single-port waveguide 1, a single-port waveguide side sliding rail plate 2, a single-port waveguide side sliding rail plate 3, a single-port waveguide side waveguide fixing plate 4, a curved waveguide 5, a low noise amplifier 6, a straight waveguide 7, a multi-port waveguide side waveguide fixing plate 8, a multi-port waveguide side sliding rail plate 9, a multi-port waveguide side sliding rail plate 10, a multi-port waveguide 11, an intermediate fixing plate 12, and waveguide fixing plates on both sides 13;

[0036] Four low noise amplifiers 6 are mounted on the waveguide fixing plate 8 on the multi-port waveguide side; one end of two curved waveguides 5 and one straight waveguide 7 are mounted on the waveguide fixing plate 8 on the multi-port waveguide side, and the other end is mounted on the waveguide fixing plate 4 on the single-port waveguide side; the single-port waveguide side slide rail plate 3 and the multi-port waveguide side slide rail plate 9 are respectively mounted (by screws) on the single-port waveguide side waveguide fixing plate 4 and the multi-port waveguide side waveguide fixing plate 8; the single-port waveguide 1 and the multi-port waveguide 11 are respectively mounted (by screws) on the single-port waveguide side slide rail groove plate 2 and the multi-port waveguide side slide rail groove plate 10; the upper and lower two intermediate body fixing plates 12 and the two side waveguide fixing plates 13 are fixed on the single-port waveguide 1 and the multi-port waveguide 11. The low noise amplifier, the straight waveguide, the curved waveguide, the single-port waveguide side waveguide fixing plate and the multi-port waveguide side waveguide fixing plate can be fixed together through the intermediate body fixing plate 12. The single-port waveguide, the single-port waveguide side slide rail groove plate, the multi-port waveguide side slide rail groove plate and the multi-port waveguide can be fixed together by the waveguide fixing plates 13 on both sides. The single-port waveguide side slide rail groove plate 2 is provided with a single-port slide rail groove 21, and the single-port waveguide side slide rail plate 3 is provided with a single-port slide rail 31; the single-port waveguide side slide rail plate 3 cooperates with the single-port slide rail groove 21 of the single-port waveguide side slide rail groove plate 2 through the single-port slide rail 31 to form a transverse sliding structure;

[0037] The multi-port waveguide side slide rail plate 10 is provided with multi-port slide rail grooves 101, and the multi-port waveguide side slide rail plate 9 is provided with multi-port slide rails 91; the multi-port waveguide side slide rail plate 9 cooperates with the multi-port slide rail grooves 101 of the multi-port waveguide side slide rail plate 10 through the multi-port slide rails 91 to form a transverse sliding structure.

[0038] The multi-channel sliding waveguide switch can realize multi-channel conduction and cutoff of microwave signals; the transmission of microwave signals is realized by sliding the waveguide port in one direction, thereby improving the switching accuracy and efficiency.

[0039] In this embodiment, a single-port choke slot 1-1 is provided at the waveguide port at the outgoing end of the single-port waveguide 1 to prevent microwave signal iteration and overflow. The single-port waveguide 1 is a microwave signal that enters from one end and passes through the waveguide tube and exits from the other end. A single-port choke slot 1-1 is left at the waveguide port at the outgoing end to prevent signal iteration and overflow.

[0040] In this embodiment, the waveguide ports at the outgoing end of the multi-port waveguide 11 are provided with multi-port choke slots 111 for preventing microwave signals from iterating and overflowing.

[0041] In this embodiment, the low noise amplifier 6 includes an SMA connector 61, a power control input terminal 62, a ground terminal 63, and a waveguide port 64. The low noise amplifier 6 is a low noise amplifier, which is an amplifier with a very low noise coefficient. It is generally used as a high-frequency or intermediate-frequency preamplifier of various radio receivers. When amplifying weak signals, the noise of the amplifier itself may seriously interfere with the signal, so it is hoped to reduce this noise to improve the output signal-to-noise ratio. The input of the microwave signal is connected to the SMA connector 61, and the power control input terminal 62 and the ground terminal 63 of the channel are connected at the same time, and the microwave signal is output through the waveguide port 64 of the low noise amplifier.

[0042] In this embodiment, the curved waveguide 5 is a channel structure for transmitting microwave signals from one end to the other end. The straight waveguide 7 is a channel structure for transmitting microwave signals from one end to the other end.

[0043] The method of using the multi-channel sliding waveguide switch is as follows:

[0044] Step 1, assembly:

[0045] like Figure 2 As shown:

[0046] 1. Install four low noise amplifiers 6 on the waveguide fixing plate 8 on the multi-port waveguide side;

[0047] 2. Install one end of two curved waveguides 5 and one straight waveguide 7 on the waveguide fixing plate 8 on the multi-port waveguide side and the other end on the waveguide fixing plate 4 on the single-port waveguide side;

[0048] 3. Install the single-port waveguide side slide rail plate 3 and the multi-port waveguide side slide rail plate 9 onto the single-port waveguide side waveguide fixing plate 4 and the multi-port waveguide side waveguide fixing plate 8 respectively;

[0049] 4. Install the single-port waveguide 1 and the multi-port waveguide 11 on the single-port waveguide side slide rail plate 2 and the multi-port waveguide side slide rail plate 10 respectively;

[0050] 5. Fix the two upper and lower intermediate body fixing plates 12 and the two side waveguide fixing plates 13 on the single-port waveguide and the multi-port waveguide;

[0051] The above completes the assembly process.

[0052] Step 2: Connect the microwave input signal:

[0053] The single-port waveguide 1 end is defined as the input end of the microwave signal, and the microwave signal can be input by the power amplifier of the corresponding waveguide port; at the same time, the four low-noise amplifiers 6 are also the input ends of the microwave signal. The multi-port end is defined as the output end and switching end of the microwave signal.

[0054] The third step is to switch the microwave signal channel:

[0055] like Figure 3 As shown, in the initial state, the microwave signal is transmitted to the output end through the single-port waveguide 1 input end, the straight waveguide 7, and then through the middle channel of the multi-port waveguide 11. The microwave signal transmitted by the low noise amplifier 6 is transmitted through the low noise amplifier No. 1 and the low noise amplifier No. 4. Figure 4 As shown, the low noise amplifier 6, straight waveguide 7 and curved waveguide 5 components are pushed to the specified position by manual or electric means, so that the microwave signal is transmitted to the output end through the single-port waveguide 1, curved waveguide No. 1 and then through channel No. 1 of the multi-port waveguide 11. At the same time, the microwave signal transmitted by the low noise amplifier 6 is also changed from the original low noise amplifier No. 1 and low noise amplifier No. 4 to the current low noise amplifier No. 2 and low noise amplifier No. 3, so that the switching of the microwave signal transmission channel is realized. Similarly, pushing the component upwards can achieve a similar effect. The utility model is not limited to having only three output waveguide ports at the output end, but can also have more, and can realize the switching function of microwave signals of one guide to three, one guide to five... one guide to multiple channels. It can be aligned through the waveguide port in a single direction, which is simple to operate and improves the accuracy and efficiency of switching.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
