Waveguide filters are mainly used in civil and commercial applications that require high frequency operation, high power handling capability, and low insertion loss.

First, in microwave communication and wireless backhaul networks, such as point-to-point microwave links and 5G/6G base station backhaul, waveguide filters are widely deployed in transmitter and receiver front ends. Their low insertion loss and excellent out-of-band rejection effectively suppress spurious signals, harmonics, and adjacent-channel interference, thereby improving link stability and overall system capacity, especially in high-power and long-distance transmission scenarios.

Second, in broadcasting and professional communication systems, waveguide filters are commonly used in television transmission systems, digital broadcasting, and fixed wireless communication equipment for channel selection and spectrum purification. Their good thermal stability and mechanical robustness help ensure consistent performance during long-term continuous operation.

In addition, in industrial and scientific equipment, waveguide filters are applied in microwave heating systems, plasma processing equipment, material testing platforms, and electromagnetic compatibility (EMC) test systems. In these applications, they are used for frequency selection, signal isolation, and interference suppression to enhance measurement accuracy and overall system reliability.
