Original Abstract

The paper describes options replacement of classical ladder band pass filters by the active coupled band-pass filters. The advantage of coupled filters is smaller spread of filter elements than in configurations of ladder filters. In comparison with a cascade synthesis method, this type of filters enables to reach smaller sensitivity of the filter element. Nevertheless, in the case of an active filter design, there are problems with active filter elements (active inductances and FDNR elements) which require relatively high quality factors and consequently, relatively high numbers of active elements (OAs). The paper deals with active coupled band pass filters in which the lossy active elements are used. At the end of the paper the esign and measurement of the realized active coupled band pass filter with active inductance (synthetic inductor) are presented.
