Abstract:
1. Gain-block for use in a mixer-system and comprising at least a first, a second, a third, a fourth and a fifth gain block-transistor, with a control electrode of the first gain-block-transistor constituting a control input of the gain-block, with a first main electrode of the first gain-block-transistor being coupled to a first main electrode and to a control electrode of the second gain-block-transistor and to a control electrode of the third gain-block-transistor, with a second main electrode of the second gain-block-transistor being coupled to a second main electrode of the third gain-block-transistor and to a voltage guiding terminal, with a second main electrode of the first gain-block-transistor being coupled to a second main electrode of the fourth gain-block-transistor and to a current guiding terminal, with a control electrode of the fourth gain-block-transistor constituting a second main electrode of the gain-block and being coupled to a second main electrode of the fifth gain-block-transistor, with a first main electrode of the fourth gain-block-transistor being coupled to a control electrode of the fifth gain-block-transistor and to a first main electrode of the third gain-block-transistor, and with a first main electrode of the fifth gain-block-transistor constituting first main electrode of the gain-block.
