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.
