  • Abstract
    An LDMOS class-AB balanced power amplifier with an attempt to use reduced-size branch-line couplers in the divider/combiner parts is presented. The proposed amplifier with a center frequency of 2.14 GHz was designed. At center frequency a size reduction and improved intermodulation distortion are achieved, comparing with the conventional branch line couplers.
