FOCUS ON THE NEWS AND APPROACH

How to Choose the Right Waveguide Switch?

Waveguide switches are critical components in many high-frequency systems, especially in radar, satellite communications, electronic warfare, and millimeter-wave testing. They enable precise signal routing, redundancy switching, and multi-path configuration. However, selecting the right switch is not always straightforward — especially when frequencies reach Ka-band, V-band, W-band, or higher.

What Are the Functions and Applications of Waveguide Switches?

Waveguide switches play a critical role in modern microwave and millimeter-wave systems. As frequency demands continue to increase in radar, satellite communications, and test systems, designers rely on waveguide switches to ensure precise signal routing, minimal loss, and high reliability. AO Microwave, as a leading RF & microwave solutions provider, offers a complete series of waveguide switches covering 5.85 GHz to 110 GHz, supporting a wide range of professional applications.

Why Screws Used in Millimeter-Wave Products Are Different

When it comes to millimeter-wave (mmWave) components, every small detail matters — even the screws. Unlike standard fasteners, the screws used in high-frequency products such as WR22, WR19, WR15, WR12, and WR10 waveguide components are specifically engineered to maintain performance integrity and reliability under extreme conditions.
