Tich mar stima: En adier maduong' mar oro signal ma frekwensi mamalo -
Tich mar stima mar RF coaxial konekta en ranyisi margi maduong’ie moloyo, ma ketho adier mar signal. Paramita madongo gin kaka:

Kuom ranyisi, ng’injo mag SMA owinjore gi ng’injo ma ni e piny mar 18 GHz, to ng’injo ma nigi 2.92 mm kata 1.85 mm nyalo konyo ng’injo ma ni e bwo 40 GHz kata ma malo. E tiyo gi frekwensi ma malo, ketho mar kondakta kod ketho mar dielektrik gin gik madongo ma geng’o.
3.Keto Loss kod Dwogo Loss
Insertion loss measures the attenuation of signal energy as it passes through a connector, typically measured in decibels (dB). Low-loss designs rely on high-purity conductors and optimized insulation materials. Return loss reflects the℃of signal reflection. High return loss (e.g., >20 dB) nyiso ni ng’ato nyalo winjo maber.

1.Kontak mar kwedo
Rezistans mar tudruok mar kondakta ma diere nyaka bed piny kaka nyalore (kaka pile<5 mΩ) to reduce heat generation and signal attenuation. Contact pressure, plating material (such as gold, silver), and tolerances directly impact contact reliability.
