USB SPNT coaxial switch series

Coaxial switches are widely used in RF/microwave systems, such as time multiplexer, time division channel selection, pulse modulation, transceiver switch, beam adjustment, etc. The indicators of the switch are relatively simple. The insert loss is as small as possible, the isolation is as large is as possible, and the VSWR is as small as possible. The frequency band and power meet the system requirements.

Microwave switching circuit

The combination of switching devices and microwave transmission lines constitutes a microwave switch assembly. The equivalent circuits of various switching devices and microwave circuits are the same. The switch is defined according to the number of interfaces, and its code is # P # T, such as SPST, SPDT, DPDT, SP6T, etc.

The microwave design of these circuits should consider the parasitic parameters of the switch to design the matching network, as well as the installation size of the devices.
