Abstract

1. A high-frequency wide band transformer circuit having a twin-hole (19) core and planar windings, a second winding (W2) being provided between an input (E) of the circuit and a first output (A), the first output (A) being connected to earth potential by way of a fourth winding (W4) and a resistor (R3) connected in series therewith, a tapping between a first resistor (R1) connected to earth and a third winding (W3) connected to a second output (S) being connected to earth by way of a first winding (W1) and a second resistor (R2), characterised in that a first conductor path (230) is disposed between that end (J) of the first winding (W1) which is remote from the second resistor (R2) and the tapping (K), and a second conductor path (240) is disposed between that end (L) of the second winding (W2) which is remote from the input (E) and that end (M) of the fourth winding (W4) which is remote from the third resistor (R3), said conductor paths being commonly disposed in an additional substrate plate (30) which is metal clad on one side and which is secured in, and at right angles to, the printed circuit board (10).
