| Zusammenfassung: | The present invention relates to an active filter for suppressing noise and inter-modulation. The filter has at least one impedance circuitry such as at least one resonator and/or at least one reactive component. A feedback loop comprising amplifier means and lines connected to it compensates for the power losses provided in the circuitry and making the filter active. At least one coupler means is provided, each as an interface between the amplifier means and the impedance circuitry. Each coupler has an impedance termination. |
