ABSTRACT:
An improved traveling wave amplifier is disclosed. The improvements to the traveling wave amplifier disclosed include designing the drain-to-drain and gate-to-gate transmission lines as coupled pairs thereby coupling energy back to the input from the output. The result is increased bandwidth without an increase in device count or resorting to a cascade configuration.
