Experimental performance of a meta-distributed amplifier

Meta-distributed amplifiers (MDAs) constitute a novel class of distributed amplifiers based on the active coupling of two composite-right/left handed transmission lines, and can provide dual-band amplification at two different physical ports. In this contribution, the dual-band gain and noise performance of such active distributed circuits is experimentally demonstrated for the first time using a lumped element-based implementation. Obtained experimental results suggest that the performance of such MDAs can be similar to that of conventional distributed amplifiers as far as gain and noise figure are concerned, but with the added advantage of dual-band amplification.
