Abstract :
This paper describes a novel microwave single stage distributed amplifier configuration based on the dual-fed distributed amplification technique. In this configuration the input and output line idle ports are reactively terminated, This results in a significant improvement in gain and power added efficiency over conventional and dual-fed distributed amplifier. The amplifier band of operation can be tuned by varying the terminating reactances. This novel configuration can also be used as a tuneable oscillator over a decade by direct feedback.<>
