Kuranko baarakɛcogo: Garanti jɔnjɔn min bɛ se ka kɛ sababu ye ka taamasiyɛnw cicogo kɔrɔta-Frequency Signal Transmission
RF coaxial connecteurs ka kuran baarakɛcogo ye u ka taamasiyɛn kɔrɔba ye, min bɛ nɔ bila taamasiyɛn dafalen na k’a ɲɛsin a ma. Paramɛtɛrɛ jɔnjɔnw ye ninnu ye:
1.Impedance (Impedance) min bɛ kɛ ni jogo ye

3.Insertion Loss ani Segin bɔnɛ
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) bɛ impedansi bɛnkan ɲuman jira.
