ABSTRACT:
An alternating voltage amplifier circuit has a plurality of semiconductor amplifier elements, preferably field effect transistors, operated in a grounded gate (base) configuration. The amplification direction is not to be determined until the application of specific operating voltages and is reversible by means of reversing such voltages. At least two semiconductor amplifier elements are provided in parallel to one another. One of the semiconductor amplifier elements is effective in one direction of amplification as an input amplifier and, with the other semiconductor amplifier element, in the other amplification direction has a power amplifier, the other semiconductor amplifier element being connectible or disconnectible upon reversal of the amplification direction.
