Introduction

This is an ultra-small series of high-pass filters designed for space-constrained applications in CATV systems, dimensions just 13x27mm.

Although short, it also has excellent electrical specifications and a one-piece robust mechanical structure.

The pass band support DOCSIS 3.1 up to 1218 MHz is available.

In addition to being used in CATV systems, they are also suitable for many communication applications such as TV, DVB-T, ATSC, Cablenet and other RF systems.
