Crystal Filter Ordering Information

Where possible, filters for a given application should be selected from the Standard Range, and ordered by quoting the appropriate filter type. If the application is such that a custom filter is required, then our engineers are available to discuss the specification and to obtain the best compromise between performance and the unavoidable cost of design and development.

Standard Filters
Hy-Q International offer a range of standard filters which cover the most common applications. These all fall into the following groups:

  GreenDot.gif (130 bytes) Channel filters
