Circuit configuration with bandpass filters

摘要

A circuit configuration for the bandpass filtering of a high-frequency signal with a large bandwidth, includes a plurality of bandpass filters which have staggered passbands and are disposed in parallel. A changeover switch which is integrated in a semiconductor module is connected to the bandpass filters on the line side. The number of outputs of the semiconductor module is equal to the number of bandpass filters. This improves the circuit configuration with respect to isolation, space requirement, component requirement and costs. Such circuit configurations can be utilized in the field of mobile radio communications.
