Abstract

1. A controlled switch for high-frequency signals having no d.c. component comprising in T-formation a series arrangement of a resistor (R2) and a diode (D1) in the first series arm connected to a signal input, a first transistor (T1) in the shunt arm, and a second transistor in the second series arm, where a control voltage can be connected to the base of the first transistor (T1) and the collector of the first transistor (T1) is connected to the diode (D1) and the base of the second transistor (T2), characterised in that the signal input (E) is connected via a first coupling capacitor (C1) to a first and second resistor (R1, R2), that the other terminal of the first resistor is connected to reference potential and the other terminal of the second resistor is connected via the diode (D1) to the collector of the first transistor (T1) and via a third resistor (R3) to a supply voltage (+Ub), that the base of the first transistor (T1) is connected via a fourth resistor (R4) to the supply voltage (+Ub) and via a control switch (S1) to reference potential, that the collector of the second transistor (T2) is connected to the supply voltage (+Ub) and the emitter of this transistor ist connected via a fifth resistor (R5) to reference potential and possibly via a further coupling capacitor (C2) to the output terminal (A), and that the diode (D1) consists of a PIN-diode.
