K&L Filter Wizard has been developed to offer a broad range of filters to satisfy customer requirements,
including environmental, power-handling, and packaging needs. On the request for quote (RFQ) screen,
K&L Filter Wizard allows the customer to explicitly specify environmental, packaging, and power
specifications for each filter selected. Temperature is addressed during the selection process and
on the RFQ screen.
Typical connectors are shown in outline drawings, but other connector types can be specified when
requesting a quote for a given performance and housing.
Custom requirements can mandate design changes to standard options submitted for quotation.
In the event that a filter selection submitted for quote does not meet all of your requirements,
K&L will contact you to suggest an alternative design. If a filter specification needs to meet
criteria other than that provided by the K&L Filter Wizard software, please contact K&L
directly at 410-749-2424.
For all products:
Due to manufacturing variations, please observe these guidelines:
- Actual attenuation at any given frequency point may vary by +/- 10%.
- Actual bandwidth may be wider than specified.
- Passband insertion loss may exceed given value by 10%.
General information about limitations of specific filter topologies are listed below.
