The detected signal-to-noise power ratio is evaluated for fiber links with periodic amplification. It is shown that the highest ratio is achieved in the limit of a distributed amplifier (g = alpha), but that, alternatively, periodic amplification at intervals of alpha(-1) entails a penalty of less than 2 dB compared with the (ideal) distributed case.

This article reports on the first demonstration of distributed amplifier monolithic microwave integrated circuits (MMICs) with a bandwidth (BW) more than 300 GHz. The three presented utilize uniform traveling-wave topology six, eight, and ten unit cells, respectively. In this article, impact connection between gate line transistors achievable performance is investigated. It demonstrated that sh...
