Tirohanga Whānui
He pūnaha tuku peka te porowhita coaxial, ā, he āhuatanga kore-tauutuutu. He hanganga pokapū āhua-Y te porowhita RF ferrite, he mea tito mai i ngā rārangi peka e toru e tohatoha ōrite ana i te koki o te 120° ki a rātou anō. Ina pāngia te porowhita e te papa aukume, ka aukumetia te ferrite. Ina whakaurua te tohu mai i te pito 1, ka whakaohokia te papa aukume ki te hononga ferrite, ā, ka tukuna te tohu ki te putanga mai i te pito 2. Waihoki, ka tukuna te tohu whakauru mai i te pito 2 ki te pito 3, ā, ka tukuna te tohu whakauru mai i te pito 3 ki te pito 1. Nā tana mahi tuku huringa tohu, ka kiia he porowhita RF.
Te whakamahinga noa o te pūihi porohita: he pūihi noa mō te tuku me te whiwhi tohu.
Ko te kaupapa mahi o te porowhita coaxial e ahu mai ana i te tuku kore-taurite o te papa aukume. Ina uru te tohu ki te raina tuku coaxial mai i tetahi taha, ka ārahihia te tohu e ngā rauemi aukume ki tetahi taha, ka wehea. Nā te mea ka mahi noa ngā rauemi aukume ki ngā tohu i ngā taha motuhake, ka taea e ngā porowhita coaxial te whakatutuki i te tuku kotahi-ara me te wehe i ngā tohu. I taua wā, nā ngā āhuatanga motuhake o ngā kaiārahi o roto, o waho hoki o ngā raina tuku coaxial me te awe o ngā rauemi aukume, ka taea e ngā porowhita coaxial te whakatutuki i te ngaronga whakaurunga iti me te wehenga teitei. He maha ngā painga o ngā porowhita coaxial. Tuatahi, he iti te ngaronga whakaurunga, e whakaiti ana i te whakaiti tohu me te ngaronga pūngao. Tuarua, he nui te wehenga o te porowhita coaxial, e taea ai te wehe pai i ngā tohu whakauru me te whakaputa me te karo i te pokanoa. Hei tāpiri, he āhuatanga whānui ngā porowhita coaxial, ā, ka taea te tautoko i te whānuitanga o ngā whakaritenga auau me te whānui. Hei tāpiri, he ātete te porowhita coaxial ki te mana teitei, ā, he pai mō ngā tono mana-teitei. He whānui te whakamahinga o ngā porowhita coaxial i roto i ngā pūnaha RF me te ngaruiti. I roto i ngā pūnaha whakawhitiwhiti kōrero, ka whakamahia ngā porowhita honohono hei wehe i ngā tohu i waenga i ngā taputapu rerekē hei ārai i ngā whakaata me ngā pokanoa. I roto i ngā pūnaha radar me te pūihi, ka whakamahia ngā porowhita honohono hei whakahaere i te ahunga o ngā tohu me te wehe i ngā tohu whakauru me ngā tohu whakaputa hei whakapai ake i te mahi a te pūnaha. Hei tāpiri, ka taea hoki te whakamahi i ngā porowhita honohono hei ine me te whakamātautau tohu, hei whakarato i te tuku tohu tika me te pono. I te wā e whiriwhiri ana, e whakamahi ana hoki i ngā porowhita honohono, me whai whakaaro ki ētahi tawhā nui. Kei roto i tēnei ko te awhe auau whakahaere, e hiahia ana kia whiriwhiria he awhe auau tika; Te wehe hei whakarite i te pānga wehe pai; Te ngaronga whakaurunga, ngana ki te whiriwhiri i ngā taputapu ngaronga iti; Te kaha tukatuka mana hei whakatutuki i ngā whakaritenga mana o te pūnaha. E ai ki ngā whakaritenga tono motuhake, ka taea te whiriwhiri i ngā tauira me ngā whakaritenga rerekē o ngā porowhita honohono.
Ko ngā taputapu mowhiti RF coaxial kei roto i ngā taputapu kore-tauutuutu. Ko te whānuitanga auau o te mowhiti RF coaxial a te RFTYT kei waenga i te 30MHz ki te 31GHz, me ngā āhuatanga motuhake pēnei i te iti o te ngaronga whakaurunga, te wehenga teitei, me te ngaru tū iti. E toru ngā taputapu tauranga o ngā mowhiti RF coaxial, ā, ko ō rātou hononga he momo SMA, N, 2.92, L29, DIN rānei. He tohunga te kamupene RFTYT ki te rangahau me te whakawhanake, te whakaputa, me te hoko i ngā taputapu āhua-porowhita RF, me te hītori o te 17 tau. He maha ngā tauira hei whiriwhiri, ā, ka taea hoki te whakarite i te tauine nui kia rite ki ngā hiahia o te kiritaki. Mena kāore te hua e hiahiatia ana e koe i te rārangi i runga ake nei, whakapā atu ki ā mātou kaimahi hokohoko.
