High pass filters for optimum signal processing

High pass filters from Wainwright Instruments are used in communication technology, measurement technology and signal processing in many other areas. While signals with lower frequencies are attenuated or blocked, high pass filters allow signals with frequencies above a certain cut-off frequency to pass. With a focus on quality and performance, our high pass filters support signal integrity and system reliability by eliminating noise and ensuring clear signal transmission.


Which high pass filter is right for you?

First, determine a few features to find the high pass filter that perfectly suits your needs. Which model is suitable for you depends, for example, on the desired cut-off frequency. Another decisive factor is how much insertion loss can be tolerated in the passband and how much attenuation is required in the stopband.
High pass filters are used in various application areas. These include:

  • Mobile communication
  • Wireless connectivity
  • Satellite navigation and communication
  • Broadcasting
  • Telemetry

The different types of high pass filters

High pass filters are important components in signal processing to pass signals above a certain frequency and block signals below that frequency. Here are some different types of high pass filters:

  • Butterworth high pass filter: A filter that has a flat frequency response in its amplitude transfer function in the passband and a steady decrease in the cutoff frequency.
  • Chebyshev high pass filter: A filter that has a sharper transition in the cut-off frequency than a Butterworth filter, but at the expense of an uneven amplitude transfer in the passband.
  • Bessel high pass filter: A filter that has a linear phase response in the passband. This means that all frequency components of the signal pass through the filter with the same delay.
  • Elliptical high pass filter: A filter that has an extremely steep slope in both the passband and stopband. This leads to a rapid decrease in amplitude outside the passband.
  • Cauer high pass filter: This type of filter has similarities to elliptical high pass filters, but places a focus on minimizing phase distortion.
Different filter types are each tailored to specific requirements and areas of application. The selection of a suitable filter depends on the desired signal characteristics, the required frequency selectivity and the tolerance to signal distortion. By applying a suitable high pass filter, you can ensure that your system or device performs optimally by effectively suppressing unwanted low-frequency signals while maintaining the integrity of the desired signal.


This list contains many of our Standard High Pass filters, as well as guaranteed specifications and prices for these. Each row represents a particular filter and by entering or selecting your required specifications, you will remove those filters from the list that don't meet or exceed your requirements. Apart from selecting various filter specifications, you can also choose to have dimensions and weight displayed in the metric or the imperial system. This choice will also be reflected on the datasheet that is generated. Lastly, you can also choose your required quantity, which will display the respective unit prices.

Should you not find a match for your requirements, please use our custom filter forms to enter your specifications and to request a quotation.

We recommend to proceed as follows:

  1. Enter your required Fco (passband cutoff frequency) in the field where it says "Enter Fco" and press return on keyboard. Now only filters that can be offered with your required Fco will remain in the list.
  2. One by one, select your other required specifications from the drop-down menus at the top of the list. As you select more specs, the list of filters will continually shrink until you are left with a single or very few relevant filters to choose from.
  3. Click Data sheet on the left of any row to view that filter's datasheet. On the datasheet itself you will still be able to adjust your Fco - if necessary - and select your preferred connectors. You can either print out the datasheet or generate a PDF for saving or emailing. You may also generate a quote request directly from the datasheet by adding the quantity required to the Quote Basket and filling out the contact form located there.
