AI Technical Summary

Technical Problem

The input and output ports of existing microwave switches are arranged in parallel on the same plane, which leads to inconvenient use in scenarios where installation space is limited or RF cable layout is limited, so the RF cable needs to be bent or cable layout is redesigned.

Method used

A microwave switch with a vertical layout of common ports is designed. The input port and the output port are not on the same plane, and the axis of the input port and the output port are arranged 90 degrees orthogonal. Through the direct interoperability of the internal electrical microwave channel, the dependence on external coaxial cable interconnection is reduced.

Benefits of technology

The design provides greater space flexibility and installation ease, simplifies the installation process and reduces the difficulty of use, reduces the length and insertion loss of transmission channels, improves the efficiency and quality of signal transmission, and makes the system more compact.

Abstract

The present invention provides a microwave switch with a common port vertical layout and a control method thereof, which relates to the field of switch technology. The microwave switch includes: a third inner conductor, one end of which is connected to the input port; a first chip transmission line, which is arranged in the lower shell, and one end of which is overlapped with the other end of the third inner conductor; a first inner conductor, one end of which is connected to the other end of the first chip transmission line; a first output port, which is arranged on the lower shell, and one end of the first output port is connected to the other end of the first inner conductor; a second chip transmission line, which is arranged in the lower shell; a second inner conductor, one end of which is connected to one end of the second chip transmission line; a second output port, which is arranged on the lower shell, and one end of which is connected to the other end of the second inner conductor. The present invention avoids the need to bend the radio frequency cable or redesign the cable arrangement, thereby simplifying the installation process and reducing the difficulty of use.
