Whakakaha Mana 0.01-1Ghz Teitei Teitei Te Haruru Iti
| Kaiārahi-mw | He kupu whakataki ki te Whakakaha Mana Haruru Iti me te Huarahi Nui |
He wāhanga nui te whakakaha haruru iti-whakanui (LNA) e mahi ana i roto i te awhe auau 0.01 ki te 1GHz i roto i ngā pūnaha whakawhitiwhiti kōrero hou me ngā tono tukatuka tohu. Kua hangaia tēnei taputapu hei whakarei ake i ngā tohu ngoikore me te whakauru i te haruru tāpiri iti, kia pai ai te kounga o te tohu mō te tukatuka, te tātari rānei i muri mai.
Ko te LNA he mea whakamahi i ngā rauemi haurua-ā-ira matatau me ngā tikanga hoahoa ara iahiko hei whakatutuki i ōna āhuatanga mahi tino pai. Ko tōna whakanui, he nui pea, ka taea te whakanui ake i ngā tohu me te kore he nui o te whakapōturi, he mea tino pai mō te whakamahi i ngā taiao e whakawhāiti ana i te kaha o te tohu, pērā i ngā whakawhitiwhitinga amiorangi, i ngā tuku ahokore tawhiti rānei.
Ko te whakahaere i runga i te roopu auau 0.01 ki te 1GHz e kapi ana i te whānuitanga o ngā tono tae atu ki te reo irirangi VHF/UHF, ngā hononga ngaruiti, me ētahi pūnaha radar. Mā te whānuitanga o te roopu whakakaha ka taea te whakarite kia hototahi ki ngā paerewa me ngā kawa whakawhitiwhiti kōrero, ka whakarei ake i tōna whānui puta noa i ngā papaaho me ngā whakamahinga rerekē.
Haunga te nui o te whakanui me te iti o te haruru, ko ētahi atu whakatakotoranga matua mō ēnei whakakaha ko te taurite i te aukati whakauru me te putanga, te rārangi, me te pumau i runga i ngā rerekētanga pāmahana. Ka whai wāhi ngātahi ēnei āhuatanga ki tō rātou pono me te whai huatanga ki te pupuri i te pono o te tohu i raro i ngā āhuatanga rerekē.
I te nuinga o te wā, he mea nui te whakamahi i tētahi whakakaha haruru iti-whakanui teitei i roto i te awhe auau 0.01-1GHz hei whakapai ake i te aro me te mahi a ngā pūnaha whakawhitiwhiti kōrero me te kimi, kia mārama ake ai, kia pono ake ai hoki te whiwhinga me te tuku tohu.
