Abstract
A model is presented for parallel and series feedback effects in distributed amplifiers, and their frequency-dependence characteristics are discussed. A six-element distributed amplifier utilizing series feedback is described. The results show a 2-dB improvement in small-signal gain over the 2-18-GHz frequency range compared to a conventional distributed amplifier using the same active device
