This contribution presents a very flexible tool for numerically evaluating the noise parameters of a transmission line subject to an arbitrary thermal gradient. Contrary to previous methods, the proposed approach allows straightforwardly to take into account possible variations of electrical parameters along the propagation direction, such as may be expected when temperature ranges between very different...
Constant input and output mismatch circles in the output load plane are introduced as the basis for low-noise amplifier design methodology. Optimum tradeoff between input and output matching levels results as the application of a design chart providing, at the same time, the corresponding stage transducer gain. The role of degenerative series feedback is studied and systematically embedded in the...
In this work an innovative GaN HEMT technology based on a scalable Gate Length (80nm, 150nm and 250nm) process with complementary integration of a Schottky Field Plate (FP) is presented. The characterization results are compared between different Gate Lengths and FP topologies configurations, fabricated on the same wafer. In particular, remarkable low noise performances (NFmin=0.87dB, GASS=10.5dB...
