Abstract

Radio signal receiving apparatus with several variable gain amplifiers mounted in parallel and including an automatic gain control device operated from the output voltage of one of the amplifiers, in particular for single impulse radar receiver, characterized in that the device includes a few PIN diodes in the input and/or output circuits of the amplifiers and in that the currents applied to the P.I.N diodes. they come from a current generator whose input is connected to one of the amplifiers by a circuit in which a voltage generator is interposed, forming the set consisting of said voltage generator, current generator and P.I.N. diode or diodes. a gain control loop in which the attenuation introduced by the diode or P.I.N diodes. in an amplifier equipped with them, it varies in a logarithmically linear way as a function of said output voltage.
