Component models for detail RF simulation of ultra-low-ESR MLCCs

January 30, 2014 // By Graham Prophet
Modelithics Inc. has added Syfer’s Ultra-Low ESR range to its component modelling library, allowing accurate simulation of the performance of the Ultra-Low ESR Series multilayer ceramic capacitors (MLCCs) in circuit simulations.

The capacitor models are integrated with a range of software applications including Agilent ADS , Agilent Genesys , and AWR Microwave Office .

Modelithics provides simulation models for RF, microwave and millimeter-wave devices. The company offers comprehensive measurement and modelling services, as well as accurate, scalable measurement-based models that integrate with a variety of EDA tools. Modelithics Global Models track how each component's performance will change with substrate characteristics and automatically scale all substrate-sensitive parasitics with nominal part value, enabling a single model to generate accurate simulations of a complete component family.

“Simulation-ready models can save designers time and money on new designs,” says Steve Hopwood, senior Applications Engineer at Syfer. “For many applications where economical, high performance is required these new Modelithics Models for our Ultra-Low ESR capacitors will be beneficial to RF and microwave designers. In particular this range of high frequency capacitors is ideal for use in RF power amplifier assemblies, mobile communications, satellite, GPS, automotive, matching networks, and wireless LAN applications.”

The Syfer Ultra-Low ESR capacitor range utilises a very stable High Q ceramic material to optimise low loss performance in systems over a temperature range from -55°C to +125°C. To offer increased reliability with superior mechanical performance Syfer’s FlexiCap termination system option is available along with various other termination options.
