A crosssectional view of a twolayer pcb illustrates this microstrip geometry as shown in figure 2. Coilcraft design support tools inductor finders power rf. Assumptions and limitations dimensions are in meters. A microstrip is created by etching a trace on a printed circuit board and is mostly used in microwave applications. This calculator computes the inductance of a microstrip etched on a pcb, which according to the arrl handbook is. So, unlike the case of microstrip, the word substrate is not appropriate. For a simple twosided pcb design where one side is a ground plane, a signal trace on the other side can be designed for controlled impedance. Coilcraft design tools powerful web tools to help you find the best parts and optimize your designs. Download saturn pcb design toolkit program includes. Description the inductance calculated using this tool is the inductance of the loop bounded by the flat conductor and the ground planes above and below the conductor.
This calculator is designed to calculate the inductance of a microstrip given its dimensions width, length and the distance of the strip from the ground plane. The following is a design tool which calculates the inductance of an air core inductor. Calculates the inductance of a planar pcb inductor. Stripline asymmetrical dual stripline coplanar structure. When loss and coupling matter, count on sonnet to deliver the results needed to match stripline, microstrip, cpw or multilayer board design to measurement.
Microstrip inductance calculator electrical engineering. Your design of directional couplers is well enhanced using our rfmicrowave cae software for the most popular designs needed in your rf. The inductance calculated using this tool is the external inductance of the loop bounded by the flat conductor and the ground plane. With over 30 years of experience, sonnet is the most published em simulation tool on the market with leading precision and efficiency. The hot conductor is embedded in a homogeneous and isotropic dielectric, of dielectric constant. This is similar to the pcairl program described in rf design magazine, november 1994, page 52. Ground plane is assumed to be perfectly conducting and of infinite extent. Arsfilters product family includes lowfrequency lumpedelement filters thru highfrequency distributed filters in stripline, microstrip and waveguide. Stripline inductance model inductance of the loop bounded by the center conductor and ground planes is. Calculates the current a via needs to raise its temperature over ambient per ipc2152.
