Features

General-purpose use through design

with separate lines without intercoupling

Use of single chokes.

Thus the insertion loss values are not

reduced under all operating current

conditions and not when operated with

artificial mains networks (AMN) or other

equipment with high leakage currents

Cable connection in filter eliminating

extra mechanical effort

Insertion loss to CISPR 17

Stopband attenuation to 40 GHz

Design

The filter cabinet consists of 2 areas.

The bottom area holds the low-frequency filter circuitry consisting of capacitors and chokes.

The top area is RF-tight. This is where the cables leading to the shielded room are connected.

The 2 areas of the cabinet are joined by an RF-tight wall, integrated into which there are coaxial

feed-through capacitors. The wall is of high-grade Cr-Ni steel material, ensuring constant and

non-corroding contact with the feed-through capacitors even in an unfavorable environment.

Access and connection

The bottom area is accessible through two doors, each fitted with a recessible handle and lock.

The top area has a specially designed lid with a dual seal that is bolted RF-tight to the cabinet.

In each area there are copper terminal rails for cable connection. Modified cable inlets and outlets

are available on inquiry.

Electrical design

Filtering is separate for each line. This maintains the specified attenuation even in the presence

of leakage current and on full load.
