    摘要: An amplifier stage for use with low-resistance AC voltage sources has first and second complimentary transistors, each having a control terminal, a current input terminal and a current output terminal. The transistors are connected together at a first junction point, a current terminal of the second complementary transistor being connected at the first junction point to a corresponding current terminal of the first complimentary transistor. The respective other corresponding current terminals of the transistors are connected to respective opposite poles of a direct current supply, so that the first transistor, the second transistor, and the direct current supply form a series connection providing a common quiescent current to the transistors. The transistors are each provided with a respective separate direct current operating voltage at a respective control terminal. The transistors are connected to receive an input AC voltage at respective corresponding current input terminals, thereby receiving the input AC voltage in parallel.

    摘要: HF mixer for changing the frequency of an alternating voltage input signal at the circuit input to an output signal supplied at the circuit output, with an input signal source for generating the alternating voltage input signal and a local oscillator for providing a heterodyne signal. The mixing stage has two transistors complementary to one another, and connected as base grounded circuits or gate grounded circuits, connected in parallel for the alternating voltage input signal. The two transistors are connected to the local oscillator in such a way that they are equidirectionally driven by the heterodyne signal, so that both transistors change simultaneously to the blocked or conductive state.
