Abstract
Transistorized antenna amplifier for low intensity uhf signals, characterized in that it is constituted by a transistor, mounted as a base, with input of the signal through an emitter and output amplified by the collector coupling the value of the input impedance by a variable capacitor and capacities separated by an inductance; the emitter and the base having the appropriate polarities, by means of non-inductive resistances, arranged according to the scheme; an inductance of high value is inserted in the polarization network of the emitter and that network and base are decoupled by separate capacitors; and the anti-resonant output circuit by means of a variable capacitor and slightly damped by an inductive resistance.
