Abstract
Formulae are derived for the gain-bandwidth products and noise figures of a variable-reactance amplifier and a convertor. It is shown that for equal gains and noise figure the convertor has a greater bandwidth than the amplifier. This is confirmed experimentally with a circuit operated as a straight amplifier and a convertor.
