摘要：

This paper demonstrates the design of a high efficiency amplifier employing a novel concept of cascaded reactively terminated single-stage distributed amplifier (CRTSSDA). In addition, CRTSSDA produces an available power gain significantly higher than conventional distributed amplifiers using the same number of active devices. Three-CRTSSDAs were designed and fabricated for EW application. The novel amplifier achieved an associated gain above 26 dB with flatness of < +/-0.5 dB, an average power added efficiency in access of 27% at an output power of 25 dBm over the 2-18 GHz with an efficiency peak of 30% at 12 GHz.
