ʻO nā Oscillators i hoʻopaʻa ʻia i ka mana Voltage

ʻO Phase Locked Voltage Controlled Oscillators, he ʻano o ka synthesizer frequency e hoʻohana ana i kahi loop-locked loop e laka i ka alapine puka i kahi hōʻailona kuhikuhi. Hoʻohana ʻia ka oscillator i hoʻopaʻa ʻia i ka volta (VCO) no ka hoʻopuka ʻana i ka alapine puka, ʻoiai ke hoʻohana ʻia ka loop-locked loop (PLL) e hoʻomalu i ka pae a me ke alapine o ka hōʻailona puka.

ʻO kāna mau hiʻohiʻona:

1. Paʻa alapine kiʻekiʻe:
Loaʻa i ka PLVCO ke kūpaʻa alapine kiʻekiʻe loa, me kahi loop-lock loop e hiki ke hoʻopau i nā hoʻololi o ka pae a me ka hoʻopili ʻana i ka walaʻau i ka hōʻailona hoʻokomo, e hopena i ka paʻa pinepine o ka hopena.
2. Laulā laula alapine hiki ke hoʻololi ʻia:
Loaʻa i ka PLVCO kahi ākea ākea hiki ke hoʻololi ʻia, a hiki ke hoʻoponopono ʻia ke alapine puka i loko o kekahi ʻano ma o ka kāohi ʻana i ka volta.
3. Haʻahaʻa pae walaʻau:
He haʻahaʻa haʻahaʻa loa ka leo o ka PLVCO, e kūpono ana i nā noi me nā koi o ka pae kiʻekiʻe, e like me ke kamaʻilio, radar, a me nā kahua ʻē aʻe.
4. Ke kū'ē leo ikaika:
ʻO ka PLVCO he kūʻē leo ikaika a hiki ke hoʻokō i ka hopena paʻa paʻa paʻa i nā kaiapuni leo kiʻekiʻe.
5. Hana wikiwiki maikaʻi:
Ke hoʻololi ka alapine hōʻailona hoʻokomo a i ʻole ka pae, hiki i ka PLVCO ke pane wikiwiki loa a hiki ke hahai koke i nā loli hōʻailona hoʻokomo; I ka manawa like, loaʻa i kāna hōʻailona hoʻopuka ke piʻi kiʻekiʻe a hāʻule i ka manawa, kūpono no nā noi hoʻololi wikiwiki.
6. ʻO ka liʻiliʻi liʻiliʻi a me ka hoʻohana haʻahaʻa haʻahaʻa:
ʻO ka PLVCO kahi pae hoʻohui kiʻekiʻe loa, liʻiliʻi liʻiliʻi, a hiki ke hoʻohana ʻia i nā mea uila liʻiliʻi. I ka manawa like, he haʻahaʻa loa kona hoʻohana ʻana i ka mana, kūpono no nā ʻōnaehana uila.

Noi:

1. Pūnaehana PLL: Hiki ke hoʻohana ʻia ʻo PLVCO e hana i nā hōʻailona kuhikuhi ma nā pūnaewele PLL (Phase Locked Loop).
2. Pūnaehana kamaʻilio: Hoʻohana nui ʻia ʻo PLVCO i nā ʻōnaehana kamaʻilio like ʻole, e like me ke kelepona kikohoʻe, nā modem, a me nā transceivers radio.
3. Ho'āʻo a ana: Hiki ke hoʻohana ʻia ka PLVCO i nā mea hoʻāʻo like ʻole a me ke ana ʻana, e like me ka spectrum analyzer, frequency meter a me ka maʻamau maʻamau.
4. Radar: Hiki ke hoʻohana ʻia ka PLVCO i nā ʻōnaehana radar like ʻole, e like me ka radar kiʻekiʻe-frequency, ground penetrating radar, a me ka radar weather.
5. Navigation: Hiki ke hoʻohana ʻia ka PLVCO i nā ʻōnaehana hoʻokele like ʻole, me GPS, GLONASS, Beidou, a me Galileo.

Kaʻaleʻaleʻahāʻawi i ka leo haʻahaʻa PLVCO ma nā alapine a hiki i 32 GHz.
