Abstract
This invention relates to a push-pull transformer for use in a high frequency push-pull amplifier. This push-pull transformer has a coaxial line whose one end is connected to an input terminal, while the other end thereof is provided with an internal conductor and an outer conductor, the internal and outer conductors being grounded through stubs. A capacitor having a proper capacity is connected between the internal conductor and the outer conductor whereby the push-pull transformer can be properly actuated in a low frequency range other than the frequency used without any necessity to enlarge the size of the stubs.
