What is an RF Low Pass Filter?

A Low Pass Filter (LPF) is a device that passes low frequency signals and blocks signals above a certain frequency. The point up to which it passes signals is called the cut off frequency. Signals beyond this cutoff frequency are attenuated. Low-pass filters are designed to reject or heavily attenuate signals that operate at a frequency above the cut-off frequency.

When looking for a low pass RF filter, keep the following parameters in mind:

Cut off Frequency: This is the frequency below which the signal is passed with minimal losses. Any signal above this frequency is attenuated.

Passband or Bandwidth: This is the frequency below the cut-off frequency.

Stopband: This is the frequency above the cut-off frequency.

Insertion Loss: This is the loss the signal will experience in the pass band of the filter. This is usually very low and is represented in dB.

Attenuation/ Rejection: The attenuation gives the measurement of how well a filter can reject the unwanted frequency components. So it is the loss in signal above the cut-off frequency. It is represented in dB. A higher attenuation is always preferred.

Power Level: This is the maximum input power that a filter can handle.

everything RF has listed RF Low Pass Filters from the leading manufacturers. Narrow down on the list of products by selecting the passband frequency, insertion loss, attenuation, power handling capability, the package type and other parameters. Once you find the RF low pass filter that meets your requirement, you can view product specifications, download datasheets, and request quotations. Your inquiry will be sent to the manufacturer and their distributors in your region who will get back to you with the required information.
