Mumunda wakakura we tekinoroji, kune shasha imwe chete yakanyarara inoita kuti data rifambiswe zvakanaka uye kubatana kwakakwana mumashandisirwo akasiyana-siyana - tambo dze coaxial dze50 ohm. Kunyange hazvo vazhinji vangasazviona, gamba iri risingazivikanwe rinotamba basa rakakosha mumaindasitiri kubva pakutaurirana kusvika kune emuchadenga. Mublog rino, tichafumura zvakavanzika zvetambo dze coaxial dze50 ohm uye tichaongorora ruzivo rwayo rwehunyanzvi, mabhenefiti uye mashandisirwo ayo. Ngatitangei rwendo urwu kuti tinzwisise mbiru dzekubatana kusina musono!
Ruzivo rwehunyanzvi uye chimiro:
Waya ye50 ohm coaxialitambo yekutumira ine impedance ine hunhu hwe50 ohms. Chimiro chayo chine zvikamu zvina zvikuru: kondakita yemukati, kondakita ye dielectric, shield yesimbi uye sheath yekunze inodzivirira. Kondakita yemukati, inowanzogadzirwa nemhangura kana aruminiyamu, inotakura chiratidzo chemagetsi, nepo kondakita ye dielectric inoshanda se insulator yemagetsi pakati pekondakita yemukati neshield. Kudzivirira simbi, kunogona kuitwa muchimiro chewaya yakarukwa kana foil, kunodzivirira kubva pakukanganiswa kwemafrequency ekunze (RFI). Chekupedzisira, sheath yekunze inopa dziviriro yemakanika kutambo.
Mabhenefiti anobatsira:
1. Kusimba Kwechiratidzo Uye Kurasikirwa Kwakaderera: Kusimba kwe50 ohm kwerudzi urwu rwetambo kunoita kuti chiratidzo chive chakakodzera, zvichideredza kupenya uye kusawirirana kwekudzivirira. Inoratidza kudzikira kwakaderera (kureva kurasikirwa kwechiratidzo) padaro refu, zvichiita kuti ive yakakodzera kushandiswa kwema frequency akawanda. Kusimba uku kwakaderera kwakakosha pakuchengetedza kutumirwa kwechiratidzo kwakavimbika uye kwemhando yepamusoro.
2. Kureba kwemafrequency: 50 ohm coaxial cable inogona kubata spectrum yakakura, kubva pamakilohertz mashoma kusvika kumagigahertz akati wandei. Kugona uku kunoita kuti ikwanise kusangana nezvinodiwa zvemashandisirwo akasiyana-siyana, anosanganisira kutaurirana, nhepfenyuro, bvunzo yeRF nekuyera, kutaurirana kwemauto uye indasitiri yendege.
3. Kudzivirira Kwakasimba: Rudzi urwu rwetambo rune chidziviriro chakasimba chesimbi chinopa dziviriro yakanaka kubva pakukanganiswa kwemagetsi kusingadiwe uye chinoita kuti masaini aendeswe zvakanaka. Izvi zvinoita kuti ive yakakodzera kune maapplication anowanzo shandiswa neRFI, akadai semasisitimu ekutaurirana asina waya uye magadzirirwo ekuyera mafrequency akakwira.
Zvikumbiro zvakapfuma:
1. Kutaurirana: Muindasitiri yekutaurirana, tambo dze50-ohm coaxial dzinoshanda semusana wekutumira masaini ezwi, vhidhiyo, uye data pakati pemashongwe ekutaurirana nemaswichi. Inoshandiswawo zvakanyanya munharembozha, kutaurirana kwesatellite, uye Internet Service Providers (ISPs).
2. Mauto nendege: Nekuda kwekuvimbika kwayo kwakanyanya, kurasikirwa kwakaderera uye kushanda zvakanaka kwekudzivirira, rudzi urwu rwetambo runoshandiswa zvakanyanya mumauto nendege. Runoshandiswa muradar system, avionics, UAVs (ndege dzisina vanhu), masisitimu ekutaurirana emauto, nezvimwewo.
3. Midziyo yemumaindasitiri neyekuyedza: Kubva kumaoscilloscopes kusvika kumanetwork analyzers, tambo ye50-ohm coaxial inowanzo shandiswa muma laboratories nemidziyo yemumaindasitiri. Kugona kwayo kutumira masaini efrequency yakakwira nekurasikirwa kushoma kunoita kuti ive yakakodzera kushandiswa kwekuyedza nekuyera kunoda simba.
mhedziso:
Kunyange zvazvo kazhinji kacho zvisingatarisirwi,Waya ye50 ohm coaxialchinhu chakakosha mumaindasitiri akawanda, ichivimbisa kubatana kusina matambudziko uye kutapurirana kwemashoko kwakavimbika. Hunhu hwayo hwekurasikirwa kushoma, dziviriro yakasimba uye huwandu hwakafara hwemafrequency zvinoita kuti ive chinhu chakakosha pakushandiswa kwemafrequency akawanda. Gamba iri risingazivikanwe rinoita basa rakakosha muma network ekutaurirana, tekinoroji yemuchadenga, michina yekuyedza maindasitiri nedzimwe nzvimbo. Saka, ngatikoshesei zvishamiso zve 50-ohm coaxial cable, iyo inogonesa kubatana kusina matambudziko munguva yedhijitari.
