Lihokelo tsa RF coaxial ke likarolo tsa bohlokoa bakeng sa -ho fetisoa ha maqhubu a phahameng. Ts'ebetso ea bona e ama ka kotloloho ts'epahalo le katleho ea litsamaiso tsa puisano, lisebelisoa tsa liteko le lisebelisoa tsa elektroniki. Ha thekenoloji ea sejoale-joale ea elektroniki e ntse e hatela pele ho maqhubu a holimo le a miniaturization, litlhokahalo tse phahameng li beoa ts'ebetsong ea motlakase, botsitso ba mochini, le maemo a tikoloho a likhokahano tsa RF coaxial. Sengoliloeng sena se tla shebisisa matšoao a mantlha a ts'ebetso ea lihokelo tsa RF coaxial le lintlha tse li susumetsang ho tsoa mahlakoreng a mararo: litšobotsi tsa motlakase, thepa ea mochini le mamello ea tikoloho.
Ts'ebetso ea Motlakase: Tiisetso ea Motlakase ea Phetiso e Phahameng ea-Frequency Signal Transmission
Ts'ebetso ea motlakase ea lihokelo tsa RF coaxial ke sesupo sa bona sa bohlokoahali, se amang ka kotloloho botšepehi ba mats'oao. Li-parameter tsa bohlokoa li kenyelletsa:
1.Impedance ea Sebopeho
Sebopeho sa ho sitisa lihokelo tsa RF coaxial hangata ke 50Ω kapa 75Ω, e hlokang ho nyallana ka thata le mohala oa phetisetso le kou ea sesebelisoa ho qoba lipontšo le tahlehelo ea matla. Ho se tsamaisane ha impedance ho eketsa sekhahla sa leqhubu (VSWR), se amang ts'ebetso ea sistimi.
2.Frequency Range
Maqhubu a phahameng a ho sebetsa a sehokedi a laolwa ke moralo wa sona. Mohlala, lihokelo tsa SMA li loketse maqhubu a ka tlase ho 18 GHz, athe likhokahano tsa 2.92 mm kapa 1.85 mm li ka ts'ehetsa maqhubu a 40 GHz ho ea holimo. Ha -a sebelisa khafetsa, tahlehelo ea conductor le tahlehelo ea dielectric ke tsona tse ka sehloohong tse thibelang.
3.Ho Kenya Tahlehelo le ho Khutlisa Tahlehelo
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) e bonts'a papali e ntle ea impedance.
4.Shielding Ka katleho
Mehaho ea coaxial e fana ka tšireletso ea motlakase ka khokahanyo ea kantle, e thibelang tšitiso ea kantle le ho fokotsa ho lutla ha lets'oao. Ho se sireletsehe ka tsela e nepahetseng ho ka baka mathata a fapa-fapaneng kapa mahlaseli a kotsi, haholo-holo -tikolohong ea ho kopanya litsamaiso tse ngata.
Ts'ebetso ea Mechini: Motheo oa Lihokelo tse Tšepahalang
Ts'ebetso ea mochini oa likhokahanyo tsa RF coaxial e netefatsa botsitso ba nako e telele-le ho ts'epahala ha likhokahanyo khafetsa:
1.Contact Resistance
Khanyetso ea ho ikopanya le conductor e bohareng e tlameha ho ba tlase kamoo ho ka khonehang (hangata<5 mΩ) to reduce heat generation and signal attenuation. Contact pressure, plating material (such as gold, silver), and tolerances directly impact contact reliability.
2.Ho Kopana Bophelo
-Lihokelo tsa boleng bo holimo li khona ho mamella linako tse makholo ho isa ho tse likete ntle le ho senyeha ho hoholo. Likhokahano tsa likhoele (joalo ka mofuta oa N-) hangata li tšoarella ho feta-mahokelo a push (joalo ka SMB), empa ea morao-rao e loketse maemo a khokahanyo ea kapele.
3.Mechanical Stability
Ho nepahala ha sehokedi, thepa ya ka tlung (jwalo ka tshepe e sa hlwekang, brass), le dintho tse thibelang{0}}ho hlephisa (jwalo ka O{1}}rings or snaps) di ama tshebetso ya yona maemong a vibrate le a tshoho.
Ho ikamahanya le maemo a tikoloho: ho tšoarella maemong a thata
Lihokelo tsa RF coaxial hangata li sebelisoa libakeng tse thata joalo ka lits'ebetso tsa kantle, tsa indasteri le tsa sefofane. Ka hona, ba tlameha ho bonts'a mamello e latelang ea tikoloho:
1.Mocheso Range
Lihokelo tse tloaelehileng li sebetsa ka har'a mocheso oa likhato tse -55 ho isa ho +165, athe mefuta e ikhethileng (joalo ka boemo ba sesole) e ka sebetsa ka mocheso o feteletseng le ho feta. Ho fetoha ha mocheso ho ka baka phapang ho li-coefficients tsa katoloso ea thepa, ho ama botsitso ba impedance.
2.Moisture Resistance le Tiiso
Lisebelisoa tsa ka ntle li hloka liqapi tse koalang (joaloka likhalase-ho{1}}metal seals kapa rubber gaskets) ho thibela ho kenella ha mongobo, ho ka bakang kutu kapa ho senyeha ha ts'ebetso ea insulation.
3.Corrosion Resistance
Ho roala holim'a metsi (joalo ka khauta kapa nickel) ho ka ntlafatsa khanyetso ea oxidation le abrasion resistance, e leng bohlokoa haholo tikolohong ea leoatle kapa ea lik'hemik'hale.
Qetello
Ts'ebetso ea lihokelo tsa RF coaxial ke sesupo se felletseng sa lintlha tsa motlakase, tsa mochini le tsa tikoloho. Ha u khetha sehokelo, nahana ka ho lekanya lintlha tsena ho latela maemo a itseng a ts'ebeliso (joalo ka khafetsa, matla, le maemo a tikoloho), ho etelletsa pele{1}}lihlahisoa tse tšepahalang tse tsoang ho mefuta e tsebahalang. Nakong e tlang, ka nts'etsopele ea 5G, likhokahano tsa sathelaete le{4}}mahlale a phetiso a data ka lebelo le phahameng, likhokahano tsa RF coaxial li tla tsoelapele ho ea ho maqhubu a holimo, tahlehelo e tlase le boholo bo bonyenyane, e leng se hlahisang mathata a sa khaotseng ho ntlafatsa ts'ebetso ea bona.
