I roto i te ao whānui o te hangarau, kotahi te toa puku e whakarite ana i te tuku raraunga maeneene me ngā hononga tino pai i roto i ngā tono maha - ngā taura coaxial 50 ohm. Ahakoa he tokomaha kāore pea e kite, he mahi nui tā tēnei toa ngaro i roto i ngā ahumahi mai i te whakawhitiwhiti kōrero ki te rererangi. I roto i tēnei tuhinga, ka hurahia e mātou ngā mea ngaro o te taura coaxial 50 ohm me te tūhura i ōna taipitopito hangarau, ngā painga me ngā tono. Kia tīmata tātou i tēnei haerenga ki te mārama ki ngā pou o te hononga korekore!
Ngā taipitopito hangarau me te hanganga:
Taura honohono 50 ohmHe raina tuku hiko tēnei me te ātete āhua o te 50 ohms. E whā ngā paparanga matua o tōna hanganga: te arataki o roto, te ārai hiko-kore, te whakangungu rakau whakarewa me te uhi tiaki o waho. Ko te arataki o roto, he mea hanga ki te parahi, ki te konumohe rānei, e kawe ana i te tohu hiko, ko te ārai hiko-kore ia e mahi ana hei ārai hiko i waenganui i te arataki o roto me te whakangungu rakau. Ko te ārai whakarewa, e taea ana te hanga i roto i te ahua o te waea whiri, te pepa konutea rānei, e tiaki ana i te pokanoa auau reo irirangi o waho (RFI). Hei whakamutunga, ka whakaratohia e te uhi o waho he tiaki ā-ringa ki te taura.
Ngā painga e whakakitea ana:
1. Te Pūmautanga o te Tohu me te Ngaronga Iti: Mā te ārai āhuatanga 50 ohm o tēnei momo taura ka whakarite kia tino pai te pūmautanga o te tohu, ka whakaitihia te whakaata me te kore ōrite o te ārai. He iti te whakaiti (arā, te ngaronga tohu) e whakaatu ana i ngā tawhiti roa, e pai ai mō ngā tono auau teitei. He mea nui tēnei āhuatanga ngaronga iti hei pupuri i te tuku tohu pono me te kounga teitei.
2. Whānui te whānuitanga o te auau: Ka taea e te taura coaxial 50 ohm te whakahaere i te whānuitanga o te auau, mai i ētahi kilohertz ki ētahi gigahertz. Mā tēnei whānuitanga o te whakamahi ka taea te whakatutuki i ngā hiahia o ngā momo tono, tae atu ki te whakawhitiwhiti kōrero, te pāho, te whakamātautau me te ine RF, ngā whakawhitiwhiti kōrero hōia me te umanga rererangi.
3. Parenga Kaha: He parenga whakarewa kaha tēnei momo taura e whakarato ana i te tiakitanga pai rawa atu i ngā pokanoa hikohiko kāore e hiahiatia, ā, e whakarite ana i te tuku tohu ma. Nā tēnei ka tino pai mō ngā tono e pāngia ana e te RFI, pērā i ngā pūnaha whakawhitiwhiti kōrero ahokore me ngā tautuhinga ine auau-teitei.
Ngā tono whai rawa:
1. Whakawhitiwhiti Kōrero: I roto i te umanga whakawhitiwhiti kōrero, ko ngā taura coaxial 50-ohm te pou tuara mō te tuku reo, ataata, me ngā tohu raraunga i waenga i ngā pourewa whakawhitiwhiti kōrero me ngā pana. He mea whakamahi whānuitia hoki i roto i ngā whatunga waea pūkoro, ngā whakawhitiwhiti kōrero amiorangi, me ngā Kaiwhakarato Ratonga Ipurangi (ISP).
2. Te ope taua me te rererangi: Nā te mea he tino pono, he iti te ngaronga me te pai o te mahi tiaki, he whānuitia te whakamahinga o tēnei momo taura i roto i ngā mara o te ope taua me te rererangi. E whakamahia ana i roto i ngā pūnaha radar, avionics, UAV (waka rererangi kore tangata), ngā pūnaha whakawhitiwhiti kōrero taumata-hoia, me ētahi atu.
3. Ngā taputapu ahumahi me ngā taputapu whakamātautau: Mai i ngā oscilloscopes ki ngā tātari whatunga, he mea whakamahi noa te taura coaxial 50-ohm i roto i ngā taiwhanga me ngā taputapu ahumahi. Nā tōna kaha ki te tuku tohu auau teitei me te iti o te ngaronga, he mea tino pai mō ngā tono whakamātautau me te ine uaua.
hei whakamutunga:
Ahakoa e warewarehia ana i te nuinga o te wā,Taura honohono 50 ohmhe wāhanga nui i roto i ngā ahumahi maha, e whakarite ana i ngā hononga tino pai me te tuku raraunga pono. Nā ōna āhuatanga ngaronga iti, te parenga pakari me te whānuitanga o te auau ka waiho hei wāhanga tino nui mō ngā tono auau teitei. He tūranga nui tā tēnei toa ngaro i roto i ngā whatunga whakawhitiwhiti kōrero, te hangarau rererangi, ngā taputapu whakamātautau ahumahi me ētahi atu mara. Nō reira, kia maioha tātou ki ngā mea whakamiharo o te taura coaxial 50-ohm, te whakahohenga wahangu o te hononga korekore i te ao matihiko.
