Introduction

This mini window filter series is designed to pass forward path (e.g. 54-1000MHz, 85-862MHz, etc.) and only pass a narrow band of return path (e.g. 15-18MHz, 20-25MHz, etc.) for application in CATV systems.

It has excellent specifications, dimensions of only 13mm x 46mm and a weight of only 19g.

It is most suitable for use in many communications applications, such as CATV, Cable Net and other RF systems.
