Ideal Microstrip Impedance Calculator
Hammerstad–Jensen single-ended microstrip model mula sa Qucs: zero trace thickness, uniform dielectric sa ideal ground plane at air sa ibabaw. Limitado sa 0.1≤w/h≤10 at 1≤εr≤20. Z0 at effective permittivity ang kinukuwenta gamit ang free-space impedance ≈376.73 Ω. Walang copper-thickness correction, solder mask, roughness, loss, dispersion, differential pair, stripline, tolerance o material lookup. Walang real-PCB, signal-integrity, safety o manufacturing guarantee. Manual ang tatlong input, lokal ang computation.
Paano gamitin
Paano gamitin
- Ilagay ang width, dielectric height at relative permittivity.
- Kalkulahin ang ideal model
- Zero-thickness quasi-static model lamang.

Mga madalas itanong
Maaari mo ring alamin
Ano ang mga palagay ng modelo?
Ipinapalagay nito ang zero trace thickness, pantay na dielectric sa ideal ground plane, hangin sa ibabaw ng trace, at single-ended microstrip sa loob ng nakasaad na w/h at εr limits.
Maaari ba itong gamiting garantiya sa disenyo ng PCB?
Hindi. Hindi kasama ang kapal ng copper, solder mask, loss, tolerance, material lookup at iba pang epekto ng totoong board; beripikahin gamit ang angkop na engineering method.
