Introduction

WF2 series is our economically priced version of window filters with one-piece zinc alloy die-cast housing design for a robust connection to prevent connector fall off.

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

In the graph below, this wf2 window filter is designed to pass forward path signals (eg. 54-1000MHz, 85-862MHz) and only through narrow-band return paths (eg. 15-18MHz, 20-25MHz) signals.

We can design different window filters according to your specifications.

For more filter products, please see our filter category.
