Ma Oscillator Olamulidwa ndi Voltage Otsekedwa a Phase

Ma Phase Locked Voltage Controlled Oscillators, ndi mtundu wa frequency synthesizer womwe umagwiritsa ntchito phase-locked loop kutseka frequency yotulutsa ku chizindikiro chofotokozera. Voltage-controlled oscillator (VCO) imagwiritsidwa ntchito popanga frequency yotulutsa, pomwe phase-locked loop (PLL) imagwiritsidwa ntchito kuwongolera gawo ndi frequency ya chizindikiro chotulutsa.

Makhalidwe ake ndi awa:

1. Kukhazikika kwa pafupipafupi kwambiri:
PLVCO ili ndi kukhazikika kwa ma frequency ambiri, yokhala ndi gawo lotsekedwa lomwe lingathe kuchotsa kusintha kwa gawo ndi kusokoneza phokoso mu chizindikiro cholowera, zomwe zimapangitsa kuti ma frequency otuluka azikhala olimba kwambiri.
2. Mitundu yosiyanasiyana yosinthika pafupipafupi:
PLVCO ili ndi mitundu yosiyanasiyana yosinthika pafupipafupi, ndipo ma frequency otulutsa amatha kusinthidwa mkati mwa mitundu ina mwa kuwongolera voliyumu.
3. Phokoso lochepa la gawo:
PLVCO ili ndi phokoso lochepa kwambiri la gawo, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito mapulogalamu omwe ali ndi zofunikira kwambiri pa gawo, monga kulumikizana, radar, ndi zina.
4. Kukana phokoso mwamphamvu:
PLVCO ili ndi kukana phokoso kwambiri ndipo imatha kupanga mphamvu yokhazikika pafupipafupi m'malo okhala phokoso lalikulu.
5. Kuchita bwino kwambiri mwachangu:
Pamene ma frequency a chizindikiro cholowera kapena gawo la kusintha, PLVCO imakhala ndi liwiro loyankha mwachangu kwambiri ndipo imatha kutsatira mwachangu kusintha kwa chizindikiro cholowera; Nthawi yomweyo, chizindikiro chake chotulutsa chimakhala ndi nthawi yokwera ndi kugwa kwambiri, yoyenera kugwiritsa ntchito mwachangu.
6. Kukula kochepa komanso kugwiritsa ntchito mphamvu zochepa:
PLVCO ili ndi mulingo wokulirapo kwambiri wolumikizirana, yaying'ono, ndipo ingagwiritsidwe ntchito muzipangizo zamagetsi zazing'ono. Nthawi yomweyo, mphamvu zake zimagwiritsidwanso ntchito pang'ono kwambiri, zoyenera makina ogwiritsira ntchito batri.

Ntchito:

1. Netiweki ya PLL: PLVCO ingagwiritsidwe ntchito kupanga zizindikiro zofotokozera mu ma netiweki a PLL (Phase Locked Loop).
2. Njira yolumikizirana: PLVCO imagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zolumikizirana, monga wailesi yakanema ya digito, ma modemu, ndi ma transceivers a wailesi.
3. Kuyesa ndi kuyeza: PLVCO ingagwiritsidwe ntchito mu zida zosiyanasiyana zoyesera ndi kuyeza, monga chowunikira cha spectrum, mita ya pafupipafupi ndi muyezo wa pafupipafupi.
4. Radar: PLVCO ingagwiritsidwe ntchito m'ma radar osiyanasiyana, monga radar yothamanga kwambiri, radar yolowera pansi, ndi radar ya nyengo.
5. Kuyenda: PLVCO ingagwiritsidwe ntchito pamakina osiyanasiyana oyendera, kuphatikizapo GPS, GLONASS, Beidou, ndi Galileo.

Qualwaveimapereka ma oscillator olamulidwa ndi voltage ya external reference phase locked ndi ma oscillator olamulidwa ndi voltage ya internal reference phase locked, ma PLVCO pa ma frequency mpaka 32 GHz.
