Introduction

This mini band reject filter series is designed to pass the CATV Return Path (e.g. 5-42MHz, 5-65MHz, etc.) and UHF Band signals and reject all other CATV channels (e.g. 55-500MHz, 85-550MHz, etc.).

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, Cablenet and other RF systems.
