Simulation models for microwave resistors reach 67GHz

Vishay has announced broadband Microwave Global Models for its Sfernice CH series resistors in 02016, 0402 and 0603 case sizes. The models are available within the Modelithics Complete Library and ‘mmWave & 5G’ Library. “Modelithics’ measurement-based models offer part value, substrate, and solder pad scalability,” according to Vishay. “They are validated up to 67GHz and accurately predict parasitic effects ...

One I missed – poly crystalline diamond heat spreader

A polycrysalline diamond heat spreading material with thermal conductivity many times that of copper was introduced by De Beers subsidiary Element Six in 2019, and I missed it. This is far from the only similar material to exist, but this one has the highest thermal conductivity of anything that Element Six has released commercially:  2,200W/m.K (Wm-1K-1, ...
