Sichuan Keenlion Microwave Technology——Passive devices

Sichuan Keenlion Microwave Technology Yakhazikitsidwa mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ndi omwe amapanga zida za Passive Mircrowave ku Sichuan Chengdu, China.
Timapereka zigawo za mirrowave zogwira ntchito kwambiri ndi ntchito zina zofananira ndi ntchito za microwave kunyumba ndi kunja. Zogulitsazo ndizotsika mtengo, kuphatikiza zogawa mphamvu zosiyanasiyana, zolumikizira zowongolera, zosefera, zophatikizira, ma duplexer, zida zongopanga zokha, zodzipatula komanso zozungulira. Zogulitsa zathu zidapangidwa mwapadera kuti zizitha kusiyanasiyana komanso kutentha kwambiri. Zofotokozera zitha kupangidwa molingana ndi zomwe makasitomala amafuna ndipo zimagwira ntchito pamagulu onse odziwika komanso otchuka omwe ali ndi ma bandwidth osiyanasiyana kuchokera ku DC mpaka 50GHz.

Zida zopanda pake
Zipangizo zopanda pake ndi gulu lofunikira la zida za microwave ndi RF, zomwe zimagwira ntchito yofunika kwambiri paukadaulo wa microwave. Zomwe zimapangidwira makamaka zimaphatikizapo ma resistors, capacitors, inductors, converters, gradients, ma network ofananira, ma resonator, zosefera, zosakaniza ndi zosinthira.

Mtundu wa chipangizo
Chiyambi cha zamoyo
Zomwe zimapangidwira makamaka zimaphatikizapo ma resistors, capacitors, inductors, converters, gradients, ma network ofananira, ma resonator, zosefera, zosakaniza ndi zosinthira. Chigawo chamagetsi chomwe chingasonyeze makhalidwe ake popanda magetsi akunja. Zigawo zomwe zimangokhala ndi zida zodzitetezera, zochititsa chidwi komanso za capacitive. Chodziwika bwino chawo ndi chakuti amatha kugwira ntchito pakakhala chizindikiro popanda kuwonjezera mphamvu mu dera.

wotsutsa
Pamene panopa akudutsa kondakitala, katundu amene kukaniza mkati kondakitala amalepheretsa panopa amatchedwa kukana. Zigawo zomwe zimagwira ntchito yotchinga panopa mu dera zimatchedwa resistors, zomwe zimatchedwa resistors mwachidule. Cholinga chachikulu cha resistor ndikuchepetsa mphamvu yamagetsi, kugawa magetsi kapena shunt. Amagwiritsidwa ntchito ngati katundu, ndemanga, kugwirizana, kudzipatula, etc. m'madera ena apadera.
Chizindikiro cha kukana mu chithunzi cha dera ndi chilembo R. Chigawo chokhazikika cha kukana ndi Ohm, chomwe chimalembedwa ngati Ω. Nthawi zambiri amagwiritsidwa ntchito ndi kiloohm KΩ ndi megaohm mΩ.
IKΩ=1000Ω 1MΩ=1000KΩ

capacitor
Capacitor ndi chimodzi mwazinthu zodziwika bwino pamabwalo apakompyuta. Ndi gawo losungira mphamvu zamagetsi. Capacitor imapangidwa ndi ma conductor awiri ofanana kukula ndi mtundu wopangidwa ndi wosanjikiza wa insulating medium. Pamene magetsi akugwiritsidwa ntchito kumapeto kwa capacitor, magetsi amasungidwa pa capacitor. Kamodzi palibe magetsi, malinga ngati pali dera lotsekedwa, lidzatulutsa mphamvu yamagetsi. Capacitor imalepheretsa DC kudutsa dera ndipo imalola AC kudutsa. Kukwera kwafupipafupi kwa AC, kumapangitsanso mphamvu yodutsa. Chifukwa chake, ma capacitor nthawi zambiri amagwiritsidwa ntchito m'mabwalo olumikizirana, kusefa modutsa, mayankho, nthawi ndi kusinthasintha.
Chilembo cha capacitor ndi C. Chigawo cha capacitance ndi farad (cholembedwa ngati f), chomwe chimagwiritsidwa ntchito kwambiri μF (njira yaying'ono), PF (ie μμF. Pico njira).
1F=1000000μF=10^6μF=10^12PF 1μF=1000000PF
Makhalidwe a capacitance mu dera ndi nonlinear. The impedance to current amatchedwa capacitive reactance. Capacitive reactance imayenderana mosagwirizana ndi mphamvu komanso ma frequency azizindikiro.

Inductor
Monga capacitance, inductance ndi gawo losungiramo mphamvu. Ma inductors nthawi zambiri amapangidwa ndi ma coil. Mphamvu yamagetsi ya AC ikagwiritsidwa pa malekezero onse a koyiloyo, mphamvu yamagetsi yamagetsi imapangidwa mu koyilo, zomwe zimalepheretsa kuti koyiloyo isasinthe. Cholepheretsa ichi chimatchedwa inductive resistance. The inductive reactance imagwirizana mwachindunji ndi inductance ndi kuchuluka kwa chizindikiro. Simalepheretsa DC yapano (mosasamala kanthu za kukana kwa DC kwa koyilo). Chifukwa chake, gawo la inductance m'mabwalo amagetsi ndi: kutsekereza kwaposachedwa, kusintha kwamagetsi, kulumikizana ndi kufananiza ndi capacitance pakukonza, kusefa, kusankha pafupipafupi, kugawa pafupipafupi, ndi zina zambiri.
Khodi ya inductance mu dera ndi L. Chigawo cha inductance ndi Henry (olembedwa ngati H), ndipo omwe amagwiritsidwa ntchito kwambiri ndi milliheng (MH) ndi micro Heng（μH).
1H=1000mH 1mH=1000μH
Inductance ndi gawo lodziwika bwino la ma electromagnetic induction ndi electromagnetic kutembenuka. Zomwe zimagwiritsidwa ntchito kwambiri ndi transformer.

Njira yachitukuko
1. Integrated modularization ndiye tsogolo lachitukuko cha zigawo zongokhala. Kuphatikizika kwa gawoli kumapereka mphamvu yophatikizira zigawo zogwira ntchito kapena ma modules ndi zinthu zopanda pake, ndikukwaniritsa zofunikira za kuchepetsa ma modules ndi mtengo wotsika panthawi yomweyo. Njira zazikuluzikulu zikuphatikiza: ukadaulo wocheperako wotenthetsera ceramic (LTCC), ukadaulo wowonda wafilimu, ukadaulo wa silicon wafer semiconductor, ukadaulo wa multilayer circuit board, etc.
2. Miniaturization. Kufunafuna miniaturization ndi kupepuka mumakampani opanda zingwe kumafuna zida zongopanga kuti zizipanga njira yaying'ono. Micro electro mechanical system (MEMS) imagwiritsidwa ntchito makamaka kupanga zida za RF kukhala zazing'ono, zotsika mtengo, zamphamvu kwambiri komanso zothandiza kuphatikiza.
3. Encapsulation zotsatira. Poyerekeza ndi kaŵirikaŵiri ntchito pamwamba wokwera kungokhala zigawo zikuluzikulu, kuphatikiza zigawo zikuluzikulu mu phukusi akhoza bwino kusintha kudalirika kwa dongosolo, kufupikitsa conductive njira, kuchepetsa zotsatira parasitic, kuchepetsa ndalama ndi kuchepetsa kukula kwa zipangizo.

Kusiyana pakati pa zigawo zogwira ntchito ndi zopanda pake
Zipangizo zopanda pake ndi zida zomwe zimatha kuwonetsa mawonekedwe awo akunja popanda kukhala ndi magetsi akunja (DC kapena AC). Kupatula apo, pali zida zogwira ntchito. Zomwe zimatchedwa "khalidwe lakunja" ndikulongosola kuchuluka kwa ubale wa chipangizocho, ngakhale kuti magetsi kapena magetsi, magetsi kapena maginito, kuthamanga kapena kuthamanga ndi zina zambiri zimagwiritsidwa ntchito pofotokoza ubale wake.

Titha kusinthanso magawo a rf passive malinga ndi zomwe mukufuna. Mutha kulowa patsamba losintha kuti mupereke zomwe mukufuna.
