BROADBAND NON-LINEAR CONTROL NETWORK FOR LINEAR AMPLIFIERS OF MULTIPLE AMPLIFIER LINEAR AMPLIFIERS

摘要

P It is provided, in a first branch Z1 an amplitude limiter A, to create an increasing impedance on the signal source S; in a second branch Z2, a resistor C becomes conductive only above an adjustable RF voltage. The amplitudes on the limiter A and on the variable resistor C are tuned together so that the load impedance of the source of the signal S remains constant. The control voltages required for the various channels K1 to K5 of the amplifier are obtained by linear combinations of the signals of the branches Z1 and Z2 by hybrids H, H '. / P P This construction makes it possible to obtain commands single channel multi-channel emitter, without counter-reactions, stable and insensitive to temperature variations. / P
