This article presents a wideband bias circuit with low parasitic inductance for high-power pulsed amplifiers. The proposed works similarly to the traditional in that it can ensure transmission of microwaves from power amplifier load while preventing supply. By making line shorter and wider than circuit, reduces its inductance. reduction parameters is critical reducing drain voltage overshoot pu...

The objective of this paper is to investigate a ultra-wideband (UWB) low noise amplifier (LNA) by utilizing a two-stage cascade circuit schematic associated with inductive-series peaking technique, which can improve the bandwidth in the 3 10 GHz microwave monolithic integrated circuit (MMIC). The proposed UWB LNA amplifier was implemented with both co-planer waveguide (CPW) layout and 0.15 μm G...

Wavelength routed optical switching promises low power and latency networking for data centres, but requires a wideband wavelength tuneable source (WTS) capable of sub-nanosecond at every node. We propose hybrid WTS that uses time-interleaved lasers, each gated by semiconductor amplifier, where the performance device is optimised using artificial intelligence. Through simulation experiment we d...
