the resistor 10 are of the same type of resistor the radio frequency input voltage is converted into a radio frequency current by means of the resistor 2 as a result even at high input levels no overvoltages can occur at the transistors of the amplifier stages 4 to 7 the amplifier stages 4 to 7 in each case comprise current mirrors with a constant and identical translation ratio between respective input and output currents of the amplifier stage 4 5 6 7 as a result of this the signal gain of the amplifier arrangement is particularly constant and thermostable the input stage 4 acts as a current rectifier in such a way that the output signal of the amplifier arrangement at the output 13 is voltage proportional in the case of relatively high signal power levels the output currents of the amplifier stages 4 to 7 are coupled out by means of respective clamping transistors the saturation of which is prevented by the clamping and are combined at the node k and converted directly into an output voltage by means of the resistor 10 since only small voltage swings occur in the case of the principle proposed the power requirement of the circuit is low overall since the voltage of the amplified signal is small comparatively little power is necessary to subject parasitic capacitances to charge reversal the input.
