PutumōhioI roto i ngā pūnaha RF hou,ngā wehewehe manahe wāhanga matua hei whakarite i te tohatoha me te tuku tohu whai hua. I tēnei rā, ka whakauruhia e mātou he pūnaha mahi teiteiwehewehe manamō te roopu 617-4000MHz, e whakamahia whānuitia ana i roto i ngā whakawhitiwhiti kōrero ahokore, ngā pūnaha radar, ngā whakawhitiwhiti kōrero amiorangi me ētahi atu mara.
Ngā āhuatanga o te hua:
Tewehewehe manaHe iti te ngaronga whakaurunga (mōrahi 1.0dB), e whakarite ana i te iti o te ngaronga i te wā e tuku tohu ana. I taua wā anō, ko te VSWR mōrahi i te pito whakauru ko te 1.50, ā, ko te VSWR mōrahi i te pito putanga ko te 1.30, e whakarato ana i te tuku tohu pumau me te kounga teitei. Ko tōna hapa taurite whānui he iti iho i te ±0.3dB, ā, ko te hapa taurite ā-wāhanga he iti iho i te ±3°, e whakarite ana i te ōritetanga o te tohu i waenga i ngā tauranga putanga maha, me te whakatutuki i ngā hiahia o te tohatoha tohu tino tika.
E tautoko ana i te mana tohatoha mōrahi o te 20W me te mana whakakotahi o te 1W, he pai mō ngā horopaki tono me ngā whakaritenga mana rerekē. Hei tāpiri, ko tewehewehe manahe whānui te awhe pāmahana (-40ºC ki te +80ºC), ka taea te mahi pumau i raro i ngā āhuatanga taiao uaua.
Ratonga whakaritenga me te pūtāhui:
Ka whakaratohia e mātou he ratonga whakaritenga whaiaro ki ngā kiritaki, ā, ka taea e mātou te whakarerekē i te whānuitanga auau, te momo atanga me ētahi atu āhuatanga kia rite ki ngā hiahia kia tutuki ai ngā whakaritenga o ngā tono rerekē. Ka whakaratohia e ngā hua katoa he wā whakamana e toru tau kia pai ai te kounga o ngā kiritaki me te tautoko hangarau i te wā e whakamahia ana.
He kōwhiringa tino pai tēnei whakawehe mana roopu 617-4000MHz i roto i te mara o te tohatoha tohu RF nā tōna pumau me te mahi tino pai.
