Abstract
An AM transmitter having feed forward correction to compensate for source impedance. A power supply source provides a DC operating voltage. N RF amplifiers are provided for amplifying an input signal. The amplifiers are connected to the power supply source. Each amplifier has an output circuit that, when the associated amplifier is on, supplies energy from the source to provide an output voltage at a load. Each the amplifier output circuit exhibits a source impedance that degrades the value of the output voltage. A source impedance corrector varies the value of the input signal prior to amplification by the amplifiers to compensate for any variations in the value of the output voltage caused by the source impedances.
