3.Insertion Loss ne Sanba a Wɔhwere
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) kyerɛ sɛ impedance a ɛne ne ho hyia yiye.
