Title: A direct-current controlled electronic change-over switch for high frequency lines
IPC: H03K17/60
Filed: 1962-07-05
Abstract: 949,557. Transistor gating circuits. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT m.b.H. July 5, 1962 [July 8, 1961], No. 25778/62. Heading H3T. In a switching arrangement for connecting a first high frequency line to either one of a second and third line, the lines are coupled to the switch through direct currentblocking circuits, and the switch comprising a series diode and a shunt transistor in each of the second and third lines arranged such that when a transistor is controlled at the base to be conducting the associated diode is non-conducting and vice versa. When terminal 37, Fig. 2, is negative and terminal 36 is at earth potential transistor 31 conducts and cuts off diode 22. Accordingly the path from signal input terminals 19 to terminals 30 is interrupted by the diode and shorted by the transistor. However, transistor 26 is non-conducting and diode 21 consequently conductive so that the path between 19 and 25 is open. When the potentials of the control terminals 36 and 37 are reversed terminals 19 are connected ,to 30 and blocked from 25. Further isolation of the blocked path may be effected by additional diodes such as 38 in each path. Chokes 23, 27, 32 isolate the D.C. bias supplies. The circuit may be re-arranged for balanced lines (Fig. 1, not shown). In Fig. 3, transmission lines 1 and 1<SP>1</SP> (each shown for convenience as a single line) may be connected to a normal line 10, 10<SP>1</SP> or a spare line 40. The switches may each comprise a circuit of the type shown in Fig. 1 (or shown only partly in Fig. 4 as 3, 4, 11, 12 and 3<SP>1</SP>, 4<SP>1</SP>, 11<SP>1</SP>, 12<SP>1</SP>). The line 40 is connected to the coupling transformers in series so that when the control signal renders the upper path conducting and the lower path non-conducting, transistors 11<SP>1 </SP>and 12<SP>1</SP> are conducting and short circuiting transformer 6<SP>1</SP> so that the matching to line 40 is not disturbed.
