<p>With narrow-band amplifiers whose output line is located close to the input line, an unwanted feedback may be produced which results in self-excitation of the circuit or at least in a reduction of the bandwidth. According to the invention, a supply line is arranged between the two lines, which supply line is completed with a capacitor to provide a resonant circuit which resonates at the signal frequency of the narrow-band amplifier. As result thereof, energy is withdrawn from the feedback path, causing the feedback to be reduced.</p> |
