Abstract
A semiconductor circuit for switching and/or amplitude influencing of an analog desired signal fed to the input (EA, AE) of the circuit (1) to an analog actual signal in the high-frequency range generated by the circuit at the output (AE, EA). The circuit (1) has two bipolar transistors (T1, T2) arranged with respect to one another such that the collector terminal (K1, K2) of the one bipolar transistor (T1, T2) is connected with the emitter terminal (E2, E1) of the other bipolar transistor (T2, T1) and vice-versa. The bipolar transistors (T1, T2) are controlled by a control quantity fed to the base terminals (B1, B2) of the transistors (T1, T2).
Claims16
A semiconductor circuit for at least one of switching and amplitude influencing of an input analog desired signal to provide an output analog actual signal in a high-frequency range, said circuit comprising:
- a first and a second bipolar transistor wherein a collector terminal of said first bipolar transistor is connected with an emitter terminal of said second bipolar transistor and wherein a collector terminal of said second bipolar transistor is connected with an emitter terminal of said first bipolar transistor;
- at least one control input with one of said at least one control inputs being connected respectively to a base terminal of said first and second bipolar transistors to control said first and second transistors.
A semiconductor switching circuit comprising:
- a first and second bipolar transistor connected in an anti-parallel arrangement and receiving a first signal and outputting a second high frequency range signal;
- control means responsive to an input control signal to one of control switching between the input and output by a conductive and non-conductive operation of the circuit and contact the amplitude of the input signal in a continuous manner by continuous switching between a conductive and non-conductive operation of the circuit.
