A microwave linear amplifier is described. Its pass band is equal to that of the transistors which constitute it, without being limited by the usual biasing circuits which comprise chokes and capacitors with a narrow pass band. In this amplifier, which has at least one input transistor, the gate bias at neutral point is provided by a BFL type circuit, generally used in logic circuits, the output of which is looped to the input. The input signal is applied both to the inverter transistor of the BFL circuit and to the input transistor. The same BFL circuit used in the amplification stage provides for the self-matching of the stages which can be cascaded.
