A wide-band class-B amplifier using tapered interdigital power combiners
Abstract
A tapered interdigital equal-split coupler has been designed and fabricated in a planar structure. Multioctave bandwidths of equal power splits and O deg and 180 deg phase differences were obtained. Over 20-dB improvement of the second harmonics generated from a Class-B GaAs amplifier using this coupler as a combiner was demonstrated. This approach has potential applications for GaAs MMIC amplifiers and mixers.
