PURPOSE:To increase coefficients of coupling and to increase the amount of preshooting by providing earth electrode windings in grooves of a split bobbin at the inside and outside of signal windings. CONSTITUTION:Earth electrode windings 5 and 6 are wound around winding grooves 2 continuously, signal windings 4 and 4' are wound between the two, and earth electrode windings 7 are wound continuously therein to constitute a delay line. In this case, the numbers of turns of the windings 5, 6, and 7 of this delay line are so set that desired capacity (C1+C2+C3) is obtained by the windings 4 and 4', and windings 5, 6, and 7, and the numbers of turns are set so that desired inductance is obtained by the windings 4 and 4' as shown in a connection diagram and an equivalent circuit. |
