ABSTRACT:
A gain-equalized balanced microwave transistor amplifier configuration is disclosed. Two microwave amplifier circuits provide the power amplification. An input power divider divides the input signal into two signal components which are fed to the respective amplifier circuits by two transmission lines. The outputs for the amplifier circuits are fed to an output combiner by two additional transmission lines to provide a combined output signal. The desired gain equalization is provided through the loss of power due to phase error introduced by unequal transmission line lengths connecting the microwave transistor amplifiers to the output power combiner.
