Vinthu vyakupangika
■ Mtundu wa pafupipafupi:7.8MHz〜MHz
■ Kutaya kwakuŵikamo kwakucepa
■ Kusankha chomene
■ Kulimbana na kugwedezeka, kugomezgeka chomene
Mapulogalamu
- Suzhou Hangjing wa Kuŵika Kwapasi Kutayika kwa Kristalo Sefa CFMH4 mndandanda ukugwiriskirika nchito mu UHF wayilesi siteshoni / GSM / ESM.
Uwemi wa katundu
Mtengo wa Q wakukwera chomene
Bandwidth yakupapatiza chomene na band yakusintha yakukwera, kutayika kwakuchepa chomene kwakuŵikamo.
Kukhazikika kwapadera kwa pafupipafupi
Pakati pa pafupipafupi drift ndi pachoko chomene.
setifiketi
CFMH4 yikulondezga malango gha RoHS -, ghambura kulongozga, ghambura halogen, ndipo ghakulondezga malango gha REACH.
Mafumbo ghakufumbika
Q1: Kasi nchivici ico cikupangiska kuti kutentha kuŵe na ma oscillator gha kristalo?
A: Kutentha kukupangiska kusintha kwa kukhazikika kwa pafupipafupi-kanandi kukuchemeka drift. Kuti ŵalimbane na ivi, kutentha -kulipilika (TCXO) na uvuni-kulaŵilirika (OCXO) oscillators zikupangika kuti zichepeske vyakuchitika vyanthena ivi mu vigaŵa vinandi vya kutentha.
Q2: Kasi ng'anamuro la parameter ya "kuchekura" nchivichi?
A: Kuchekura kukupima nyengo yitali-kusuntha kwa pafupipafupi uko kukuchitika chifukwa cha kusintha kwa vinthu pachokopachoko mu vigaŵa vya oscillator. Vipangizo vyapachanya -vyakukwana nga ni OCXOs vikulongora viŵelengero vyakuchepa chomene vyakuchekura (mwachiyelezgero, Pachoko panji vyakuyana na ± 1ppm / chaka), ivyo ni vyakuzirwa chomene ku mapulogalamu agho ghakukhumbikwira kugomezgeka kwa nyengo yitali.
Tag yakutentha: kuŵika pasi kutayika kwa sefa ya kristalo cfmh4, China kuŵika pasi kutayika kwa sefa ya kristalo cfmh4 ŵakupanga, ŵakupeleka
