HYBRID CIRCUIT

PURPOSE:To increase various characteristics of a hybrid circuit formed by using lump constant elements, through the addition of capacitors at the specified position. CONSTITUTION:Connecting points of chockes 1, 1' and choke coils 2, 2' are connected with a capacitor 7. The variation in the amount of coupling based on the dispersion in each element can be adjusted by variously changing the value of the capacitor 7. That is, capacitors 3-6 are taken as fixed capacitors, and after the impedance of a hybrid circuit, isolation, and flatness of coupling amount are adjusted to the best conditions, the capacitor 7 is inserted for the final adjustment. Thus, the variation in the impedance of the hybrid circuit can be avoided, the flatness of the isolation and coupling amount can be kept sufficiently, and the increase in the characteristics can be achieved.
