Lithapo tsa RF, e le sesebelisoa sa bohlokoa bakeng sa -ho fetisoa ha maqhubu a phahameng, li bapala karolo e ke keng ea nkeloa sebaka litabeng tsa likhokahano, sepakapaka, khaso, le liteko le ho metha. Litšobotsi tsa bona tsa tekheniki li ama ka kotloloho botšepehi ba matšoao, ts'epahalo ea sistimi, le ho ikamahanya le maemo lits'ebetsong tsa boenjiniere. Sengoliloeng sena se hlalosa ka mokhoa o hlophisehileng likarolo tsa mantlha tsa mehala ea RF ho latela pono ea ts'ebetso ea motlakase, thepa ea mochini, maemo a tikoloho le maemo a tloaelehileng a ts'ebeliso.
I. Ts'ebetso e Ntle ea Motlakase: Tahlehelo e Tlase le Botsitso bo Phahameng
Litlhaloso tsa mantlha tsa tekheniki ea likhoele tsa RF ke bokhoni ba tsona ba phetisetso ea mats'oao maemong a holimo. Tahlehelo e tlase ke e 'ngoe ea melemo ea bona ea mantlha. Ka ho kaonefatsa thepa ea conductor (joaloka oksijene-koporo ea mahala kapa silevera{3}}koporo e phuthetsoeng), insulation (joalo ka polytetrafluoroethylene (PTFE) kapa polyethylene e tiileng), le moralo oa ho sireletsa, phokotso ea-maqhubu a maqhubu a phahameng (hangata a ka bolokoa ho tloha ho GHz ho lekholo ho ea ho GHz) Mohlala, lithapo tsa semi-rigid coaxial li ka fumana tahlehelo e ka tlase ho 0.5 dB/mitha ho sehlopha sa 18 GHz.
Litšobotsi tse ts'oanang tsa ts'oaetso ke paramente e 'ngoe ea bohlokoa, e nang le litekanyetso tse tloaelehileng tse kenyelletsang 50Ω (e sebelisoang phetisong ea matla le lits'ebetso tsa liteko) le 75Ω (e tloaelehileng ho phatlalatso le thelevisheneng). Mamello e matla ea impedance (mohlala, ± 1%) e thibela ka katleho lipontšo tsa matšoao le ho netefatsa phetisetso e nepahetseng ea matla. Ho feta moo, ts'ebetso ea ts'ireletso e fihlelleha ka -mesh e lohiloeng ka lera (joalo ka koporo e entsoeng ka lekoti kapa alloy ea silevera) kapa meaho e kopantsoeng ea aluminiamo, e nang le tšireletso e fetang -90dB, e hatellang ho sitisoa ha motlakase (EMI) le RF dutla.
II. Mechanical Precision: Ho leka-lekanya ho feto-fetoha ha maemo le ho tšoarella
Moralo oa mochini oa likhoele tsa RF o tlameha ho leka-lekanya litlhoko tsa phetisetso ea mats'oao le maemo a nnete a ho kenya. Ho ipapisitsoe le litlhoko tsa ho feto-fetoha ha maemo, li ka aroloa e le lithapo tse thata{-tse sebetsang ka ntle ho khokahanyo e tiileng ea koporo e bolokang geometry e tsitsitseng ka mor'a ho kobeha), lithapo tsa semi-tse sebetsang ka ntle tse lohiloeng tse nang le lithapo tse ngata tse ntle tsa koporo ho fihlella ho kobeha ho laoloang), le likhoele tse kobehang khafetsa.
Khetho ea seaplane ea insulation ka kotloloho e ama thepa ea 'mele ea cable. Ka mohlala, PTFE, e nang le dielectric tse tlase haholo (hoo e ka bang 2.1) le litšobotsi tse tsitsitseng tsa mocheso (-55℃ho +260℃), e loketse ho sebelisoa libakeng tse feteletseng. Polyethylene e atolositsoeng, ka lehlakoreng le leng, e fokotsa ho fokotsa matšoao ka ho theola boima ba dielectric ha u ntse u boloka boima bo tlaase. Lisebelisoa tsa ka ntle tsa sheath (tse kang polyvinyl chloride (PVC), polyurethane (TPU), kapa fluoropolymers) li fana ka tšireletso khahlanong le ho senya, oli kapa boemo ba leholimo.
III. Moralo o Ntlafetseng oa ho Fetolana le Tikoloho
Lithapo tsa RF tsa indasteri le tsa sesole{0}li tlameha ho mamella mathata a tikoloho. Ho tsitsa ha thempereichara ho fihleloa ka ho khetha-mocheso o phahameng-lisebelisoa tse thibelang mocheso (tse kang FEP kapa ceramic-e tlatsitsoeng PTFE). Lihlahisoa tse ling li ka boloka ts'ebetso ho tloha ho -70 degrees to +400℃. Mongobo le ho hanyetsa ha kutu ho itšetlehile ka sebopeho sa tiiso ea sheath (joalo ka sekhomaretsi se cheselitsoeng sa aluminium + sekhomaretsi se chesang se chesang) kapa liphahlo tse khethehileng (tse kang polyimide) ho thibela ho kenella ha mongobo le ho senyeha ha insulation.
Bakeng sa ts'ireletso ea khatello ea maikutlo, lithapo tsa lihlomo li matlafatsa ho hatella le ho tiisa matla ka ho eketsoa ka tšepe e lohiloeng e sa hloekang kapa tepi ea tšepe e spiral, e leng se etsang hore li tšoanelehe bakeng sa ho kenngoa ka tlas'a lefatše kapa{0}}motsamaong oa koloi. Ho feta moo, -mosi o tlase oa li-zero{3}}halogen (LSZH) lisebelisuoa tsa sheathing li finyella litlhoko tsa polokeho ea mollo tsa lipalangoang tsa terene le tsa maoatleng.
IV. Likopo tse Tloaelehileng le Lintlha tsa Bohlokoa tsa Khetho
Litšobotsi tsa tekheniki tsa likhoele tsa RF li khetholla maemo a ts'ebeliso ea tsona e lebisitsoeng:
Liteishene tsa puisano le seseteme ea radar: Lithapo tse nyane-tse thata tse nang le tahlehelo e tlase le matla a phahameng a matla (joalo ka LMR series) li khethoa ho netefatsa phetisetso e tsitsitseng ea maqhubu a maqhubu a -joaloka sehlopha sa 28 GHz 5G).
Laeborari le teko le tekanyo: -lithapo tse tenyetsehang hantle tse phahameng{{0}tse kang RG-316) li sebelisoa bakeng sa ho lekanya lisebelisoa tse joalo ka li-vector network analyzers (VNAs) ka lebaka la ho tsitsisa ha tsona.
Sathelaete le sepakapaka: Lithapo tsa Ultra-tse bobebe (joaloka micro-coaxial structures) tse kopantsoeng le mahlaseli-lisebelisoa tse sa tsoeng mahlaseling li kopana le litlhoko tsa tikoloho e feteletseng.
Ha u khetha thapo, nahana ka mefuta ea maqhubu, matla a matla, sebaka se kobehang, le lithibelo tsa litšenyehelo. Ka mohlala, -mesebetsi ea maqhubu a phahameng a hloka ho shebisisa cable's voltage standing wave ratio (VSWR), ha -matla a holimo a hloka optimized conductor cross{{3}sectional area le moralo oa ho tima mocheso.
Tsoelo-pele ea theknoloji lithapong tsa RF e tsoela pele ho ntlafatsa ntlafatso ea-litsamaiso tse phahameng tsa elektroniki. Ho tloha ho saense ea lintho tse bonahalang (e kang nanocomposite insulation layers) ho ea ho mekhoa e mecha (e kang meralo ea coaxial e otlollang), meeli ea ts'ebetso ea bona e lula e sutumetsoa. Nakong e tlang, ka tsoelopele ea likhokahano tsa 6G, thekenoloji ea terahertz, le boenjineri ba litaba tsa quantum, lithapo tsa RF li tla tsoela pele ho ea ho ultra-wideband, ultra-tahlehelo e tlase, le bokhoni bo bohlale, ho fetoha borokho ba mantlha bo hokahanyang lefatše la 'mele le la dijithale.
