Window Filters
 
Introduction

WF3 series is our round version of window filters with shorter copper housing.

The window filter contains one band-pass and one low-pass and / or one high-pass.

In the graph below, this WF3 window filter is designed to pass forward path signals (550-1000MHz) and only through narrow-band return paths (20-50MHz) signals.

We can design different window filters according to your specifications.

For more filter products, please see our filter category.

To learn more filter types please see the filter profile technical notes in our Tech Support.
