Lowpass

All Information is Proprietary and owned by Networks International Corporation , a Kansas Company.

The table below shows various lowpass filters many of which may be customized according to your specifications. Package modifications are also available. Surface mount versions are often available for the SMA packages as are connectorized versions of the surface mount packages. Call or email your custom specifications for a prompt review and quotation. Check back often for new additions.
