Extending the frequency range of microwave resistors

30-11-2020 | Vishay | Passives

The Optoelectronics group of Vishay Intertechnology, Inc offers the availability of new broadband Microwave Global Models for Vishay Sfernice CH series resistors in the 02016, 0402, and 0603 case sizes. The new models are offered within the Modelithics COMPLETE Library and mmWave and 5G Library.


Modelithics' measurement-based models provide part value, substrate, and solder pad scalability. They are validated up to 67GHz and precisely predict parasitic effects based on the model parameter settings, making them ideal for high-frequency applications.


The model libraries combine seamlessly with popular EDA tools, including Keysight Technologies' PathWave ADS, Keysight Technologies' PathWave RF Synthesis (Genesys), Cadence AWR Design Environment, Cadence Virtuoso Spectre RF, Ansys HFSS, and Sonnet Suites. As a sponsoring Modelithics vendor partner, the company's customers receive a free 90-day trial of Vishay data in the Modelithics component library.


CH series microwave resistors are unique in their capacity to be used up to 50GHz. Devices in the 02016 case size with ohmic values in the range of 50Ohm to 100Ohm are validated for service at frequencies up to 70GHz. This exceptional performance makes the series an excellent choice for very high-frequency needs, such as next-generation millimeter-wave 5G networks and radar applications.
