CMOS VCXO Oscillators
ʻO kāu mea hoʻolako CMOS VCXO Oscillators
ʻO Suzhou Hangjing Elec & Tech Co., Ltd., i hoʻokumu ʻia i ka makahiki 2014, he ʻenehana -ʻenehana liʻiliʻi a me ka liʻiliʻi-ʻoihana nui (SME) kūikawā i ka - spectrum R&D piha, hoʻolālā, hana, a me ke kūʻai ʻana i nā ʻāpana hoʻomalu alapine quartz. Hoʻokumu ʻia i loko o kahi hui ʻoihana a me ka ʻike hana ʻoihana kiʻekiʻe, ua hoʻomohala ka hui i kahi kōpili huahana ikaika e hoʻopili ana i nā kristal quartz, nā oscillator kristal, TCXO, VCXO, OCXO, nā kānana aniani-mai nā ʻāpana kumu a i nā ʻōnaehana i hoʻopili ʻia.

![HCMOS Puka VCXO Oscillator 3225]()
HCMOS Puka VCXO Oscillator 3225ʻO ka HCMOS output VCXO Oscillator 3225 VC32H6 Series he 3.2x2.5mm HCMOS surface -mount device (SMD) e hōʻike ana i kahi pūʻolo seam sealing. Hoʻolālā mua ʻia no a hoʻohana nui ʻia ma Cable modem...Heluhelu hou
No ke aha e koho ai iā mākou
ʻOi aku ka maikaʻi
ʻO ke kaulahao hoʻolako pololei e hōʻoia ana i ka maikaʻi o ka huahana; ʻO ka -kiʻekiʻe haʻahaʻa haʻahaʻa i hōʻoia ʻia e ka hoʻāʻo ʻana;
Pono lawelawe
He kaʻina lawelawe -concentric (e uhi ana i ke kūkākūkā mua-kūʻai no ka hoʻouna ʻana i-kākoʻo kūʻai) e hana mua i ka pane wikiwiki . 24-lawelawe lawelawe pūnaewele, ka manawa kūpono a me ka wikiwiki no ʻoe.
Makeke kuai
Ua hoʻonui ʻia kā mākou huahana i nā ʻāpana honua koʻikoʻi me ʻEulopa, Asia Hema, ʻAmelika, Oceania, a me nā mākeke nui ʻē aʻe. Hiki i kēia pūnaewele puni honua ke hāʻawi i ke kākoʻo piha i nā mea hana uila alakaʻi a puni ka honua, me ka mālama ʻana i ka manaʻo nui i nā huahana kiʻekiʻe.
ʻO kā mākou palapala hōʻoia
Ua hala kā mākou huahana a pau i ka GB/T 19001 - 2016/ISO 9001:2015 Quality Management System Standard, hōʻike kēia i ko lākou hoʻokō ʻana i nā kūlana honua no ka maikaʻi, palekana, a me ka hana.
ʻO ka walaʻau haʻahaʻa VCXO Oscillator 7 X 5
ʻO ka haʻahaʻa -phase-oscillator VCXO oscillator (7×5 puʻupuʻu) he uila-oscillator kristal i mālama ʻia i loko o kahi pūʻolo 7mm×5mm paʻa. ʻO kāna hiʻohiʻona koʻikoʻi ka hoʻoponopono alapine ma o ka mana voltage ʻoiai e hāʻawi ana i ka hana haʻahaʻa haʻahaʻa haʻahaʻa. Loaʻa kēia koena o ka paʻa kiʻekiʻe, ka haʻahaʻa haʻahaʻa, a me ka leo haʻahaʻa i nā noi alapine kiʻekiʻe, e lilo ia i mea kumu kumu uʻi ma nā kamaʻilio, wikiō, hoʻāʻo, a me nā ʻoihana.

Ke ʻano o ka walaʻau haʻahaʻa VCXO Oscillator 7 X 5
Nā VCXO Crystal Quartz
Ke hoʻohana nei i kahi aniani quartz ma ke ʻano he resonator, hoʻohana lākou i kāna hopena piezoelectric a me nā waiwai vibration mechanical e hana i nā alapine. Hoʻohana ʻia lākou i nā noi e like me 5G base station, optical network lako, a me ka satellite navigation, kahi e koʻikoʻi nui ai ka maʻemaʻe pinepine.
MEMS (Micro-Electro-Mechanical System) VCXOs
Ke hoʻololi nei i nā kristal quartz me nā resonator MEMS (e like me ka silicon -hoʻokumu ʻia), loaʻa iā lākou ka hana alapine ma o ka capacitive a i ʻole ka piezoresistive sensing. He liʻiliʻi lākou a loaʻa ka mana haʻahaʻa haʻahaʻa: ʻoi aku ka liʻiliʻi ma mua o 10mW, e kūpono iā lākou no nā polokalamu kelepona.
5G kahua kahua
E lawelawe ma ke ano he kumu hoailona kuhikuhi no na kaapuni modulation kikoho'e, e hooiaio ana i ka pa'a o ka -wikiwiki lawe 'ikepili.
ʻO nā mea hana pūnaewele Optical
Hāʻawi i kahi kumu wati haʻahaʻa -jitter ma nā kikowaena pūnaewele 25G/100G e hōʻemi i ka hōʻemi ʻana i ka hōʻailona.
wikiō a me ka hoʻolaha
Hoʻopuka i nā alapine kuhikuhi e like me 148.5MHz a me 297MHz e hoʻohālikelike i nā uaki wikiō wikiō (e laʻa, 27MHz ma 1080p). Pono ka leo o ka pae ma lalo o -115dBc/Hz ma ke alapine 10kHz no ka pale ʻana i ke kiʻi ʻana a i ʻole nahae.
Hoao a ana
Hāʻawi i kahi kumu wati -kiʻekiʻe e hōʻoia i nā hualoaʻa ana pololei. I ka hoʻokele satellite a me nā ʻōnaehana hoʻokele lele, kū i nā kaiapuni wela loa a hāʻawi i ka mana alapine paʻa.
ʻOihana ʻenehana
E mālama i ka paʻa i loko o ±25ppm ma nā kaiapuni wela kiʻekiʻe (-40 degere a +85 degere) a kūpono me nā ʻāpana hoʻomalu ʻoihana ʻenehana e like me TI Sitara a me STM32H7.
E mālama i ka wā e hoʻohana ai i ka walaʻau haʻahaʻa VCXO Oscillator 7 X 5
Laulā Voltage:E pili pono i ka laulā Vc i kuhikuhi ʻia ma ka ʻikepili (e laʻa, 0.5V a i 3.3V). Hiki ke ho'opau a poino paha ke oi aku i keia laula.
Hoʻoponopono Linearity:Inā makemake ʻia ka mana pololei kiʻekiʻe, e hoʻohui i kahi op amp e pale i ka hōʻailona Vc e hōʻemi i nā hopena hoʻouka.
Kāohi walaʻau:E hoʻokaʻawale i ka laina Vc mai nā hōʻailona māmā -kiʻekiʻe a hoʻohui i nā pahu ferrite no ke kānana ʻana.
Hoʻolālā hoʻoheheʻe wela: High-power VCXOs (e.g., >1W) koi i ka wela wela a i ʻole ka wela wela e hōʻoia i ka emi o ka wela o ka hui ʻana ma mua o 85 degere.
Pākuʻi Mahana:Inā loli nui ka mahana ambient, e hoʻohana i ka hana TCXO a i ʻole e hoʻopili i kahi mea ʻike wela o waho no ka uku ikaika.
Kaʻina kau ʻana:Hōʻalo i ke kaomi pololei ma luna o ka VCXO (hiki ke hōʻino i ke aniani). Paipai ʻia ka Socket a i ʻole SMD soldering.
Hoʻokaʻawale haʻalulu:No nā mea kaʻa kaʻa a i ʻole aerospace, e hoʻohui i nā pad hoʻopuʻi -e hōʻemi i ka hopena o ka haʻalulu mechanical ma ka alapine.
Ka mālama a me ka ho'āʻo
Hoʻopili maʻamau
Kalibrasi pinepine:Ma ka liʻiliʻi loa i hoʻokahi makahiki, e hoʻohana i ka helu alapine (e like me ka Agilent 53132A) no ka hōʻoia ʻana aia ka alapine o ka hoʻopuka i loko o ka waiwai nominal ± ka laulima huki -up.
Hōʻike noise Phase:I kēlā me kēia ʻelua makahiki, e hoʻohana i kahi mea nānā kikoʻī (e like me ka R&S FSWP) a i ʻole ka mita leo ʻāpana (e like me ka Keysight E5052B) e hōʻoia i nā kikoʻī.
Hoʻoponopono pilikia
ʻAʻohe puka:E nānā inā ʻo ka volta lako mana a me ka Vc aia i loko o ka laulā a inā ʻaʻole hemo ke kūʻai.
Ka neʻe pinepine ʻana:E hōʻoia inā ʻoi aku ka mahana ma mua o ka palena a i ʻole he ʻokoʻa ke kaha huki -up.
ʻO ka hoʻohaʻahaʻa ʻana i ka walaʻau:E nānā no ka walaʻau lako mana, pale ʻole, a i ʻole nā kumu hoʻopilikia ikaika ma kahi kokoke.
Nā Kūlana Waihona
Ka Mahana a me ka Humidity:Pono e ho'omalu 'ia ke kaiapuni waihona ma waena o -10 degere a me +60 degere, me ka ha'aha'a ha'aha'a o lalo a i 'ole like me 60% no ka pale 'ana i ka ma'ama e ka aniani a me ka ne'e pinepine.
Kūʻē -Static:E hoʻohana i ke kāʻei lima anti{0}}static i ka wā e hana ai no ka pale ʻana i ka pōʻino ESD i nā kaapuni pili.
