An LC low-pass filter is a microwave filtering device that allows signals below the cutoff frequency to pass through, while preventing signals above the cutoff frequency from passing through.It can be customized according to customer requirements.

LC band-pass filters have the advantages of low insertion loss, high stopband attenuation, good temperature stability, few required passive components, and light weight. They are widely used in miniaturized RF modules and components in fields such as navigation, radar, and electronic anti-interference. Their operating frequency range is 1 MHz to 10 GHz.

A high-pass filter is a device that can filter out low-frequency signals. High-frequency signals can pass through normally, while low-frequency signals that exceed the set threshold will be blocked or attenuated. This filter can be customized according to the customer's requirements.

Cavity band-pass filters are the most common passive components in the communications industry. They allow signals within a specific frequency range to pass while blocking signals in other frequency ranges, thereby achieving selective signal transmission. They can be customized according to customer requirements.

The function of this cavity band-stop filter is the complete opposite of a band-pass filter: it can suppress signals within a specific frequency range while allowing signals outside that frequency range to pass through. In other words, it can filter out mid-frequency signals and retain high- and low-frequency signals. This filter can be customized according to the customer's requirements.
