A class B microwave, push-pull, balanced amplifier and amplifying element for use therein is disclosed. A field-effect transistor having at least two gates, two drains and a common source has, inter alia, a center-tapped output transformer connected across the drains. A branch including a DC voltage source connects the center-tap of the transformer and the common source of the field effect transistor. Parasitic loss mechanisms associated with the source contracts and leads are eliminated because the current in the branch connecting the source to the transformer is not at the signal frequency. The FET can comprise a semiconductor body having alternating drain and source electrodes with gate electrodes therebetween. Source electrodes are connected to one output terminal. The remaining drain electrodes are connected to the other output terminal. The two gate electrodes lying between any two gate consecutive drain electrodes are respectively connected to opposite input terminals.
