[SatNews] Isola has announced a free Impedance and Power-Handling Calculator that predicts the design attributes for microstrips and striplines based on the design’s target impedance and dielectric properties of the company’s RF, microwave and millimeter-wave laminate materials.
This new tool supports Isola’s earlier announcement of a Design Review Service, in which its technical staff will provide PCB fabricators and OEMs all of the calculations, testing, characterizations and material recommendations needed to convert to Isola’s materials. This service is offered in the wake of the global shortage of competitive RF substrates.
Isola’s new software tool provides a design or an equivalent dielectric constant to facilitate modeling for PCB designers to predict impedance and other design attributes. The software computes changes in the effective dielectric constant due to dispersion at higher frequencies. The software then computes the total insertion loss—a measure of power lost through heat for power handling calculations, including the dielectric loss, conductor loss, and the loss due to the surface roughness. The main factors affecting the typical power-handling capability of a material are its thermal conductivity, the maximum operating temperature, and the total insertion loss.
The Impedance and Power-Handling Calculator is available for download at https://isodesign.isola-group.com/phi-calculator/.
