Problems solved by technology

The disadvantage of this method is that the positioning time is long (by measuring the general switching time is 400-600ms, it is difficult to meet some special occasions of fast switching), and the impact resistance is low (in some high-shock vibration occasions, it is easy to appear chattering phenomenon) , affecting the overall communication performance) and high cost (the price of permanent magnetic materials has increased year after year, which has also increased the cost of magnetic positioning structures, making it difficult to enter the low-end civilian product market)

Embodiment Construction

[0023] The overall structure of the waveguide switch of the present invention is as follows figure 1 As shown, it consists of four parts: electrical connector 1, motor assembly 2, housing 3 and guide assembly 4. The explosion diagram of the assembly is shown in figure 2 As shown, the cross-sectional view is as image 3 a, 3b shown. The electrical connector 1 and the motor assembly 2 are fixed above the casing 3 , and the casing 3 is buckled on the guide assembly 4 . The guidance system adopts the C-type double-pole double-throw structure design. The design principle is based on the idea that the guidance system can be replaced. The same drive control component can be matched with different waveguide cavities to realize the general design scheme of multi-interface and multi-band switches. The motor assembly 2 includes an electromagnetic actuator and a transmission mechanism. The limited rotation angle motor is used to realize 90-degree reciprocating rotation, the guide rotor...

Abstract

A rapid-switching high-frequency waveguide switch comprises an electric coupler (1), a motor assembly (2), a shell body (3) and a guided assembly (4). The electric coupler (1) and the motor assembly (2) are fixed above the shell body (3), and the shell body (3) is buckled and connected on the guided assembly (4). The guided assembly (4) achieves switching of two radio frequency passages through two arch-shaped passage holes. The motor assembly (2) is used as a drive system, achieves rapid rotation of a guided rotor, produces location locking torque, and achieves movement precise control and movement location of ninety-degree-angle movement. The rapid-switching high-frequency waveguide switch has the advantages of being simple and reliable in structure, low in difficulty of processing and assembling, free from introducing extra non-metallic material, capable of achieving rapid switch of a switch on the premise of guaranteeing the microwave performance of the switch.

Description

technical field [0001] The invention belongs to the field of microwave communication and relates to a waveguide switch based on a rectangular waveguide. Background technique [0002] Rectangular waveguide is one of the earliest types of transmission lines used to transmit microwave signals. The transmission frequency ranges from 1GHz to over 220GHz. It is still widely used in large-scale communication projects. Among them, the waveguide switch, as an important component of signal path control, has been widely used in the backup path switch of high-power output radar and communication transmitters; it is also used in microwave transmitting equipment and microwave measurement and control projects of satellite communication systems. Realize switching between the antenna and unloading channel on the microwave power signal. [0003] The waveguide switch is one of the key parts of the satellite signal transmission system. The current waveguide switch is mainly a mechanical waveg...
