Electrical Performance: High-Frequency Signal Transmission neih theihna tur Core Guarantee
RF coaxial connector-te electrical performance hi an indicator pawimawh ber a ni a, signal integrity direct-in a nghawng a ni. Parameter pawimawh tak takte chu:
1.A nihna takah chuan Impedance a awm
RF coaxial connector-te characteristic impedance chu 50Ω emaw 75Ω emaw a ni tlangpui a, signal reflection leh power hloh loh nan transmission line leh device port nena strict matching a ngai a ni. Impedance mismatch hian standing wave ratio (VSWR) a tisang a, hei hian system efficiency a nghawng bawk.
2.Frequency Range a ni

Entirnan, SMA connector hi 18 GHz hnuai lam frequency tan a tha a, 2.92 mm emaw 1.85 mm emaw connector hian 40 GHz leh a aia sang frequency a support thei bawk. High-frequency application-ah chuan conductor hloh leh dielectric hloh hi a tihkhawtlai ber a ni.
3.Insertion hloh leh Return hloh
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) hian impedance matching tha tak a tarlang.
