DLC75N performance curve

Sa S21 curve ng capacitor, mayroong ilang mga parallel resonance point (V-shaped attenuation point). Ang unang parallel resonance frequency FPR ay ang frequency ng pinakamababang parallel resonance point. Hindi ito apektado ng kapal ng substrate at ang dielectric na pare-pareho, ngunit ito ay naiimpluwensyahan ng direksyon ng pag-install ng kapasitor. Ang pahalang na direksyon ay nangangahulugan na ang panloob na mga plato ng elektrod ng kapasitor ay kahanay sa substrate.

Sa input impedance [Zin] curve ng capacitor, mayroong ilang mga series resonant point (V-shaped attenuation point). Ang unang serye ng resonant frequency FSR ay ang dalas ng pinakamababang series resonant point. Sa puntong ito, ang haka-haka na bahagi ng input impedance Im[Zin] ay zero (Im[Zin] = 0). Sa ibaba ng FSR, ang tunay na bahagi ng Re[Zin] at ang haka-haka na bahagi ng Im[Zin] ng input impedance ay hindi nagbabago nang linear sa dalas. Ang laki ng FSR ay nauugnay sa mga sumusunod na salik: ang istraktura ng mga panloob na electrodes ng kapasitor, ang materyal ng substrate, ang kapal ng substrate, ang dielectric na pare-pareho ng substrate, ang direksyon ng pag-install ng kapasitor sa substrate, at ang laki ng mga substrate pad.

Kahulugan at mga kondisyon ng pagsukat:

Kahulugan: Ang kapasitor ay konektado sa serye sa linya ng microstrip. Iyon ay, ang kapasitor ay naka-bridge sa pagitan ng dalawang dulo ng isang 50-ohm microstrip na linya na may puwang. Mga kondisyon ng pagsukat: Ro3006 Rogers substrate na may dielectric constant na 6.15, ang kapal ng substrate ay pahalang na naka-install sa 10 mils, ang microstrip gap ay 6 mils, at ang microstrip width ay 14.1 mils. Ang reference plane ay nasa gilid ng sample. Ang lahat ng data ay mula sa electrical model na binuo ng Modelithics Inc., na nakabatay sa malaking halaga ng data ng pagsukat sa iba't ibang substrate.
