Ukadaulo wa Microwave wa Sichuan Keenlion——Zipangizo zopanda ntchito

Ukadaulo wa Microwave wa Sichuan Keenlion womwe unayamba mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ndiye wopanga wamkulu wa zida za Passive Mircrowave ku Sichuan Chengdu, China.
Timapereka zida za mirrowave zogwira ntchito bwino komanso ntchito zina zokhudzana ndi ntchito za microwave kunyumba ndi kunja. Zogulitsazi ndizotsika mtengo, kuphatikizapo zida zosiyanasiyana zogawa mphamvu, zolumikizira zolunjika, zosefera, zophatikiza, zoduplex, zida zosinthira zamagetsi, zosungunulira ndi zozungulira. Zogulitsa zathu zimapangidwa mwapadera kuti zigwirizane ndi malo osiyanasiyana otentha kwambiri. Mafotokozedwe amatha kupangidwa malinga ndi zosowa za makasitomala ndipo amagwiritsidwa ntchito pa ma frequency band onse omwe ali ndi ma bandwidth osiyanasiyana kuyambira DC mpaka 50GHz.

Zipangizo zopanda ntchito
Zipangizo zosinthika ndi gulu lofunika kwambiri la zipangizo za microwave ndi RF, zomwe zimagwira ntchito yofunika kwambiri muukadaulo wa microwave. Zipangizo zosinthika zimaphatikizapo ma resistors, ma capacitor, ma inductors, ma converters, ma gradients, ma network ofanana, ma resonators, ma filters, ma mixer ndi ma switch.

Mtundu wa chipangizo
Chiyambi cha mitundu
Zigawo zosinthika makamaka zimaphatikizapo zotsutsana, ma capacitor, ma inductor, ma converter, ma gradients, ma network ofanana, ma resonator, ma filters, ma mixer ndi ma switch. Chigawo chamagetsi chomwe chingawonetse mawonekedwe ake popanda magetsi akunja. Zigawo zosinthika makamaka ndi zida zosinthika, zosinthika komanso zosinthika. Chinthu chomwe zimafala kwambiri ndichakuti zimatha kugwira ntchito pakakhala chizindikiro popanda kuwonjezera mphamvu mu dera.

choletsa
Pamene mphamvu yamagetsi imadutsa mu kondakitala, mphamvu yomwe kukana kwamkati kwa kondakitala kumalepheretsa mphamvu yamagetsi imatchedwa kukana. Zigawo zomwe zimagwira ntchito yoletsa mphamvu yamagetsi mu circuit zimatchedwa resistors, zomwe zimatchedwa resistors mwachidule. Cholinga chachikulu cha resistor ndikuchepetsa mphamvu yamagetsi, kugawa mphamvu yamagetsi kapena shunt. Imagwiritsidwa ntchito ngati katundu, feedback, coupling, isolation, ndi zina zotero m'ma circuit ena apadera.
Chizindikiro cha kukana mu chithunzi cha dera ndi chilembo R. Chigawo chokhazikika cha kukana ndi Ohm, chomwe chimalembedwa ngati Ω. Zomwe zimagwiritsidwa ntchito kwambiri ndi kiloohm KΩ ndi megaohm mΩ.
IKΩ=1000Ω 1MΩ=1000KΩ

kapitomu
Capacitor ndi chimodzi mwa zigawo zodziwika bwino m'mabwalo amagetsi. Ndi gawo losungira mphamvu zamagetsi. Capacitor imapangidwa ndi ma conductor awiri ofanana kukula ndi khalidwe lofanana okhala ndi wosanjikiza wa insulating medium. Voltage ikagwiritsidwa ntchito kumapeto onse a capacitor, mphamvu yamagetsi imasungidwa pa capacitor. Voltage ikapanda kugwira ntchito, bola ngati pali dera lotsekedwa, imatulutsa mphamvu yamagetsi. Capacitor imaletsa DC kudutsa mu dera ndipo imalola AC kudutsa. AC ikachuluka, mphamvu yodutsa imakhala yolimba. Chifukwa chake, ma capacitor nthawi zambiri amagwiritsidwa ntchito m'mabwalo olumikizirana, kusefa kwa bypass, feedback, timing ndi oscillation.
Khodi ya kalata ya capacitor ndi C. Unit ya capacitance ndi farad (yolembedwa ngati f), yomwe imagwiritsidwa ntchito kwambiri μF (njira yaying'ono), PF (monga μμF. njira ya Pico).
1F=1000000μF=10^6μF=10^12PF 1μF=1000000PF
Makhalidwe a capacitance mu dera si olunjika. Impedance ku mphamvu yamagetsi imatchedwa capacitive reactance. Capacitive reactance imafanana kwambiri ndi capacitance ndi ma signal frequency.

Inductor
Monga capacitance, inductance ndi gawo losungira mphamvu. Ma inductor nthawi zambiri amapangidwa ndi ma coil. Pamene AC voltage ikugwiritsidwa ntchito kumapeto onse a coil, mphamvu ya electromotive yomwe imayambitsa imapangidwa mu coil, zomwe zimalepheretsa kuti magetsi adutse mu coil kuti asasinthe. Cholepheretsa ichi chimatchedwa inductive resistance. Inductive reactance imagwirizana mwachindunji ndi inductance ndi pafupipafupi ya chizindikiro. Sichilepheretsa DC current (mosasamala kanthu za DC resistance ya coil). Chifukwa chake, ntchito ya inductance mu ma electronic circuits ndi: current blocking, voltage transformation, coupling and matching with capacitance for tuning, filtering, frequency select, frequency division, etc.
Khodi ya inductance mu dera ndi L. Unit ya inductance ndi Henry (yolembedwa kuti H), ndipo yomwe imagwiritsidwa ntchito kwambiri ndi milliheng (MH) ndi micro Heng (μH).
1H=1000mH 1mH=1000μH
Kusinthasintha kwa magetsi ndi gawo lodziwika bwino la kulowetsedwa kwa magetsi ndi kusintha kwa magetsi. Ntchito yofala kwambiri ndi transformer.

Malangizo a chitukuko
1. Kuphatikizika kwa modularization ndi njira yopititsira patsogolo chitukuko cha zinthu zopanda ntchito. Module yophatikiza imapereka kuthekera kophatikiza zinthu zogwira ntchito kapena ma module ndi zinthu zopanda ntchito, ndipo imakwaniritsa zofunikira zochepetsera ma module ndi mtengo wotsika nthawi imodzi. Njira zazikulu ndi izi: ukadaulo wa ceramic wotentha kwambiri (LTCC), ukadaulo wa filimu yopyapyala, ukadaulo wa silicon wafer semiconductor, ukadaulo wa bolodi la ma circuit layer ambiri, ndi zina zotero.
2. Kuchepetsa mphamvu zamagetsi. Kufunafuna kuchepetsa mphamvu zamagetsi komanso kupepuka m'makampani opanda zingwe kumafuna zipangizo zopanda mphamvu kuti zipangidwe pang'onopang'ono. Dongosolo lamagetsi la Micro electro mechanical (MEMS) limagwiritsidwa ntchito makamaka kuti zigawo za RF zikhale zochepa, zotsika mtengo, zamphamvu komanso zothandiza kuphatikiza.
3. Kugwira ntchito kwa encapsulation. Poyerekeza ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri pamwamba, kuphatikiza zinthuzo mu phukusi kungathandize kwambiri kudalirika kwa dongosololi, kufupikitsa njira yoyendetsera zinthu, kuchepetsa zotsatira za tizilombo toyambitsa matenda, kuchepetsa ndalama ndikuchepetsa kukula kwa zipangizo.

Kusiyana pakati pa zigawo zogwira ntchito ndi zosagwira ntchito
Zipangizo zongogwiritsa ntchito mphamvu zokha ndi zipangizo zomwe zimatha kusonyeza makhalidwe awo akunja popanda mphamvu yakunja (DC kapena AC). Kupatula apo, palinso zipangizo zogwira ntchito. Chomwe chimatchedwa "khalidwe lakunja" ndi kufotokoza kuchuluka kwa ubale wa chipangizocho, ngakhale kuti mphamvu yamagetsi kapena mphamvu yamagetsi, mphamvu yamagetsi kapena mphamvu yamagetsi, kuthamanga kapena liwiro ndi zina zimagwiritsidwa ntchito kufotokoza ubale wake.

Tikhozanso kusintha zinthu za rf passive malinga ndi zomwe mukufuna. Mutha kulowa patsamba losinthira kuti mupereke zofunikira zomwe mukufuna.
