Waveguide Switch
Prodct Introduction
As a core path-control component in RF microwave systems, Waveguide Switch primarily solves the problem of flexible signal routing between multiple waveguide channels or devices. Through rational structural design and high-performance material selection, it achieves rapid, low-distortion signal switching between different waveguide ports, avoiding signal crosstalk and ensuring the overall stability of the system. According to the switching principle, common Waveguide Switches include mechanical waveguide switches and solid-state waveguide switches ; according to the number of ports, they can be categorized into 2-port, 4-port, and multi-port types.

FAQ
Q: How to choose a waveguide switch that suits my system?
A: The selection should be based on four core factors: the type of waveguide and the operating frequency band of the existing system; The required number of ports and switching speed; System insertion loss index and isolation index; Application environment.
Q: Can Waveguide Switch be used in high-power RF systems?
A: Yes, but high-power models need to be selected. These models adopt high-power-resistant materials and heat dissipation structures to avoid component burnout caused by high-power signals. When placing an order, specify the system's peak power and average power to ensure compatibility.
