Abstract
In an active circuit which separates and amplifies signals received via an antenna (A) into a higher-frequency FM band and a lower-frequency FM band, weakening of the FM signals by the AM-band amplifier is avoided by adding, to the previously known circuit which has first, second, and third capacitors (C1, C2, C3), a third inductance (L3) between the second (C2) and third (C3) capacitors, and by removing any serial inductance from the adaptor or matching circuit (AP) at the input of the FM amplifier stage (UKW).
