SWITCHABLE FREQUENCY FILTER
First Claim
1. A changeover filter for filtering out a variable frequency band from a signal which is guided via an electrical main line from an input to an output of the filter,with a first line segment, which leads away from the main line, and at least one second line segment which can be electrically connected to the first line segment, and at least two electronically controllable switching elements, by means of which the first and the at least one second line segment can be connected.

Abstract
The invention relates to a filter, for example, a switchable harmonic filter for the gigahertz range. A first line segment, which can comprise a radial stub leads away from a main line of the filter. A second line segment can be electrically connected to the first line segment. At least two electronically controllable switching elements are provided, by means of which the first and the second line segment can be connected.
