Abstract

The invention discloses a waveguide switch with a novel structure, which comprises a control device and a rotor assembly, a control rotating shaft of the control device is connected with a motor shifting block, the motor shifting block is provided with a slip ring, a rotor rotating shaft of the rotor assembly is connected with a rotor shifting block, and the slip ring is slidably clamped in a chute of the rotor shifting block. According to the waveguide switch, the 90-degree special micromotor is matched with the rocker sliding block transmission mechanism, 90-degree reciprocating rotation of the motor is converted into 90-degree rotation of the rotor, and four-channel corner cut conversion is achieved; a manual switching mechanism is designed to meet the requirement of manual control in the mechanical assembly and joint test process, and dual control of electric control and manual control is achieved; and after setting in place, an automatic power-off measure ensures the safety of the waveguide switch. According to the waveguide switch, the complexity of a control circuit is reduced, the insertion loss is small, the isolation degree is high, the bearing power is large, the performance is stable and reliable, and the safety is high.

Description

technical field [0001] The invention belongs to the field of microwave communication, in particular to a waveguide switch with a new structure. Background technique [0002] The waveguide switch is an important component of signal path control. Its main function is to select the link transmission channel through the switching of the radio frequency channel, thereby greatly improving the reliability of the link system. Compared with other waveguide switches, the electromechanical microwave waveguide switch has the characteristics of low standing wave, small insertion loss, and large power capacity. It is widely used as a backup channel switch for high-power output radar and communication transmitters; it is also used in satellite communications. Systematic microwave launch equipment and microwave measurement and control engineering. [0003] S-band waveguide switches are mainly used in high-frequency receiving and transmitting subsystem links. They can automatically switch b...
