Abstract :
This paper presents a novel tunable low-pass active filter aiming to protect the DVB-H receiver against the signals coming simultaneously from the GSM band and from the Digital dividend band. The filter concept is based on a high order low pass filter at which an active capacitor circuit has been added. This later allows to compensate the overall losses of the filter and makes it tunable for a worldwide usability.
