RF cable hi high-frequency signal transmission atana key medium a nih avangin communication system stability leh rintlaknaah direct impact a nei a ni. A assembly method hian materials science, electromagnetic field theory, leh precision manufacturing process te coordinated optimization a huam a, core component pali: conductor, insulation layer, shielding layer, leh sheath te chu analysis a ngai a ni.
Conductor hi RF cable lungphum a ni a, a tlangpuiin high-purity copper (oxygen-free copper ang chi) emaw silver-plated copper wire hmanga siam a ni a, hei hian resistance hniam leh conductivity tha tak a neih theih nan a pui a ni. Single-strand solid conductor hi high-precision application atan a tha a, stranded conductor erawh chuan flexibility nasa zawk a pe a, dynamic wiring environment-ah hman a ni fo bawk. Conductor diameter leh surface finish chu target frequency range nen strict taka inmil tur a ni a, chutiang chuan skin effect avanga signal attenuation a awm loh nan.
Insulation design hian cable characteristic impedance leh dielectric loss chu direct-in a nghawng a ni. Thil hman tlanglawn tak takte chu polyethylene (PE), polytetrafluoroethylene (PTFE), leh foam dielectrics te an ni. Solid PE insulation hian man tlawm leh mechanical strength sang tak a pe a, mahse dielectric constant sang tak a nei bawk. PTFE hi a low loss property avang hian high-frequency application atan chuan duhthlan tur tha ber a ni a, foamed structure erawh chuan dielectric density tihhniam hmangin signal transmission loss a ti tlem lehzual thung. Insulation layer thickness chu conductor leh shield inkarah electromagnetic wave uniform propagation a awm theih nan characteristic impedance formula (50Ω emaw 75Ω standard ang chi) hmanga chiang taka chhut a ngai a ni.
Shielding layer hi electromagnetic interference (EMI) tihtawp nana core barrier a ni a, metal braid, aluminium foil emaw, a pahnih inzawmkhawm emaw hmanga siam a ni. Double-layer shielding (aluminum foil + braid ang chi) hian shielding effectiveness chu 80dB aia sangin a tisang thei a, medical equipment leh aerospace ang chi application harsa tak takah a tha hle. Braid density 90% aia tam chuan pawn lam ri chu a block tha hle a, aluminum foil layer hian high-frequency interference lakah radial protection dang a pe bawk.
Jacket material hian environment nena inmil leh mechanical protection a balance tur a ni. Flame-retardant PVC hi industrial environment tlangpui atan a tha a, polyurethane (TPU) emaw fluoroplastics te erawh chuan specialized application, high-temperature leh oil-corrosion resistance-ah an tha hle thung. Jacket-a abrasion resistance leh UV resistance hian cable service life a nghawng nghal vek a ni.
A tawi zawngin, RF cable-te composition method hian multi-material collaborative design leh precise process control hmangin conductivity, insulation, shielding effectiveness leh environmental adaptability inkara balance a neih a ngai a, a tawpah chuan communication base station atanga satellite link thlenga high{1}}frequency transmission mamawh chu a tlin a ngai a ni.
