Description

Technical Field

[0001] The utility model is a switching matrix of high-power multi-channel coaxial switches. Background Art

[0002] RF switches are commonly used devices in RF and wireless transmission systems. They have important applications in basic scientific research, nuclear physics, military, agriculture, medical, communications, electronic countermeasures, radio and television, and other fields. Its main function is to complete the switching of microwave signal or microwave power transmission paths. Multiple RF switches can form a switch switching matrix. By switching and controlling multiple RF switches, the switching function of the switch switching matrix can be realized. As needed, the switch switching matrix can contain multiple RF switches, and the matrix can realize a very responsible switching connection function.

[0003] RF switching switches include a variety of structural methods, the most common of which are mechanical switching switches, diode switches, relay switches, etc. RF switches of different structures have their own characteristics and can be used in different RF systems. The switching speed of diode switches and relay switches is faster, and the switching time can reach tens of microseconds or even shorter, but the high-frequency power capacity of these two structural switches is limited. The high-frequency power capacity of relay switches is generally several kW, while the maximum power that diode switches can withstand is only tens of W. Compared with diode switches and relay switches, although the switching speed of mechanical switching switches is slower, the time to complete a switching is generally in the range of hundreds of milliseconds to tens of seconds, but mechanical switching switches have a larger high-frequency power capacity. According to needs, the power level of RF mechanical switching switches can reach hundreds of kilowatts or even megawatts. RF mechanical switching switches can be divided into coaxial switches, waveguide switches and other RF mechanical switches according to different interface specifications. Different coaxial switch switching matrices are usually required in different occasions to meet different working conditions, but this will increase costs, so a coaxial switch switching matrix with multiple connection functions is required to meet different needs.
