ABSTRACT:
A feedforward amplifier compensates for distortions introduced by a main amplifying device by comparing the amplified signal with the original unamplified signal and producing a correction signal, which is related to the difference. The correction signal is combined with the main amplified signal at a combiner. The combiner takes the form of a tetrode or pentode valve which acts as a current source and which is designed so as to constitute part of an output transmission line having a predetermined characteristic impedance. By this means the combiner does not adversely affect the main amplified signal and the capacitance inevitably associated with a tetrode or pentode valve is utilized as part of the reactance of the transmission line and does not adversely affect the frequency response of the amplifier.
