RF cable, senzira yakakosha yekufambisa-frequency signal transmission, ine simba rakananga pakugadzikana nekuvimbika kwenzira dzekufambiswa kwemashoko. Iyo nzira yekubatanidza inosanganisira yakarongedzerwa optimization yezvigadzirwa zvesainzi, electromagnetic field theory, uye nemazvo ekugadzira maitiro, zvinoda kuongororwa kwezvikamu zvina zvakakosha: conductor, insulation layer, shielding layer, uye sheath.
Kondakita ndiyo hwaro hwetambo dzeRF uye inogaro gadzirwa ne-mhangura yakachena (yakaita seoxygen-yemhangura isingabhadhari) kana sirivheri-waya yakapfava yemhangura kuti ive nechokwadi chekuramba uye kuita zvakanaka. Single{{4}makondukita akasimba anokodzera-makurodha epamusoro, nepo makondakita akamiswa achipa kuchinjika kukuru uye anowanzo shandiswa munzvimbo dzinochinja waya. Iyo conductor dhayamita uye kupedzisa kwepamusoro kunofanirwa kunyatsoenderana kune inotangwa frequency renji kudzivirira kudzikamisa chiratidzo kunokonzerwa nekuita kweganda.
Iyo insulation dhizaini inobata zvakananga tambo hunhu impedance uye dielectric kurasikirwa. Zvishandiso zvakajairika zvinosanganisira polyethylene (PE), polytetrafluoroethylene (PTFE), uye foam dielectrics. Solid PE insulation inopa yakaderera mutengo uye yakakwira mechaniki simba, asi zvakare ine yakakwira dielectric inogara. PTFE, nekuda kwekudzikira kwayo kwekurasikirwa, ndiyo sarudzo inosarudzika yeakakwira-mafambiro ekushandisa, nepo zvimiro zvine furo zvichiwedzera kuderedza kurasikirwa kwekutapurirana nekudzikisa density ye dielectric. Ukobvu hweiyo insulation layer hunofanirwa kunyatso kuverengerwa zvichienderana nehunhu impedance formula (yakadai se50Ω kana 75Ω yakajairwa) kuve nechokwadi chekuparidzirwa kwakafanana kwemafungu emagetsi pakati pe conductor nenhoo.
Iyo shielding layer ndiyo yakakosha chipingamupinyi chekudzvanya electromagnetic interference (EMI) uye inoumbwa nesimbi braid, aluminium foil, kana musanganiswa wezviviri. Kaviri-layer shielding (senge aruminiyamu foil + braid) inogona kuwedzera kushanda kwekudzivirira kusvika kudarika 80dB uye inokodzera maapplication arikuda akadai semichina yekurapa neyemuchadenga. Density ye braid inodarika 90% inovharisa zvakanaka ruzha rwekunze, ukuwo aruminiyamu foil layer inopa imwe dziviriro yeradial pakukanganiswa kwepamusoro-nguva zhinji.
Iyo jekete zvinhu zvinofanirwa kuenzanisa kuenderana kwezvakatipoteredza uye kuchengetedzwa kwemichina. Flame-isingadzoreki PVC inokodzera nharaunda dzemaindasitiri, ukuwo polyurethane (TPU) kana fluoroplastics inokunda mukushandisa kwakasiyana-siyana sekukwirisa-tembiricha neoiri{3}}kuramba kuita ngura. Iyo bhachi yeabrasion kuramba uye UV kuramba inokanganisa zvakananga hupenyu hwesevhisi yetambo.
Muchidimbu, nzira yekugadzira tambo dzeRF inoda kuwana chiyero pakati pe conductivity, insulation, kudzivirira kushanda nesimba uye kuchinjika kwezvakatipoteredza kuburikidza nezvakawanda-material collaborative dhizaini uye nemazvo maitiro ekutonga, uye pakupedzisira kuzadzikisa zvinodiwa zvepamusoro-frequency transmissions kubva pacommunication base stations to the satellite links.
