Ngā Oscillator Whakahaere Ngaohiko Maukati Āhua (PLVCO) Tohutoro o Waho Tohutoro o Roto
Ngā Oscillator Whakahaere Ngaohiko Maukati Āhua
Ko ngā Oscillator Whakahaere Ngaohiko Maukati Āhua, he momo whakahiato auau e whakamahi ana i te porowhita maukati-āhua hei maukati i te auau putanga ki tētahi tohu tohutoro. Ka whakamahia te oscillator whakahaere-ngaohiko (VCO) hei whakaputa i te auau putanga, ko te porowhita maukati-āhua (PLL) ia hei whakahaere i te āhua me te auau o te tohu putanga.
Ko ōna āhuatanga ko:
1. Te pumau o te auau teitei:
He tino teitei te pumau o te auau o te PLVCO, me te koropiko raka-wāhanga ka taea te whakakore i ngā huringa wāhanga me te pokanoa haruru i roto i te tohu tāuru, ka hua ake he pumau auau teitei ake o te putanga.
2. Whānui te whānuitanga o te auau ka taea te whakarite:
He whānui te awhe auau ka taea te whakarite i te PLVCO, ā, ka taea te whakarite i te auau putanga i roto i tētahi awhe mā te whakahaere i te ngaohiko.
3. Haruru iti-wāhanga:
He iti rawa te haruru ā-wāhanga o te PLVCO, nō reira he pai mō ngā tono he nui ngā whakaritenga ā-wāhanga, pērā i te whakawhitiwhiti kōrero, te radar, me ētahi atu mara.
4. Ātete haruru kaha:
He kaha te ātete o te PLVCO ki te haruru, ā, ka taea e ia te whakatutuki i te putanga auau pono me te pumau i roto i ngā taiao haruru nui.
5. He mahi tere tino pai:
Ina huri te auau, te wāhanga rānei o te tohu tāuru, he tere rawa te urupare a te PLVCO, ā, ka taea e ia te whai tere i ngā huringa o te tohu tāuru; I te wa ano, he nui te pikinga me te hekenga o te tohu putanga, he pai mō ngā tono whakawhiti tere.
6. Rahi iti me te iti o te whakamahinga hiko:
He tino teitei te taumata whakauru o te PLVCO, he iti te rahi, ā, ka taea te whakamahi i roto i ngā taputapu hiko iti. I taua wā anō, he iti rawa te whakamahinga hiko, he pai mō ngā pūnaha pākahiko.
Taupānga:
1. Whatunga PLL: Ka taea te whakamahi i te PLVCO hei whakaputa tohu tohutoro i roto i ngā whatunga PLL (Phase Locked Loop).
2. Pūnaha whakawhitiwhiti kōrero: E whakamahia whānuitia ana te PLVCO i roto i ngā pūnaha whakawhitiwhiti kōrero maha, pērā i te pouaka whakaata mamati, ngā pouwhanga, me ngā taputapu whakawhiti reo irirangi.
3. Whakamātautau me te ine: Ka taea te whakamahi i te PLVCO i roto i ngā taputapu whakamātautau me te ine maha, pērā i te tātaritanga whānuitanga, te mita auau me te paerewa auau.
4. Radar: Ka taea te whakamahi i te PLVCO i roto i ngā pūnaha radar maha, pērā i te radar auau-tiketike, te radar uru whenua, me te radar huarere.
5. Whakatere: Ka taea te whakamahi i te PLVCO ki ngā pūnaha whakatere maha, tae atu ki te GPS, GLONASS, Beidou, me Galileo.
Qualwavee whakarato ana i ngā orooro e whakahaeretia ana te ngaohiko raka ā-wāhanga tohutoro o waho me ngā orooro e whakahaeretia ana te ngaohiko raka ā-wāhanga tohutoro o roto, ko ngā PLVCO i ngā auau tae atu ki te 32 GHz.
