ABSTRACT:
An amplifier including an input circuit tuned to the frequency to be amplified and receiving as an input the signal to be amplified, a first transistor connected in common base, the emitter of which is coupled to the input circuit and the collector of which provides the output signal of the amplifier, and a feedback circuit feeding back to the base of the transistor a fraction of the output voltage. The feedback circuit includes a capacitive bridge and a second transistor. The input circuit can be used in a first stage of the amplifier or of a mixer.
