Sichuan Keenlion Microwave Technology Tau tsim muaj xyoo 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. yog lub chaw tsim khoom ua ntej ntawm cov khoom siv Passive Mircrowave hauv Sichuan Chengdu, Suav.
Peb muab cov khoom siv mirrowave ua haujlwm tau zoo thiab cov kev pabcuam cuam tshuam rau kev siv microwave hauv tsev thiab txawv teb chaws. Cov khoom lag luam pheej yig, suav nrog ntau yam khoom faib hluav taws xob, cov khoom sib txuas lus, cov lim dej, cov khoom sib txuas, cov khoom duplexer, cov khoom sib cais ua haujlwm, cov khoom cais thiab cov khoom sib xyaw. Peb cov khoom lag luam tau tsim tshwj xeeb rau ntau qhov chaw ib puag ncig thiab qhov kub thiab txias. Cov lus qhia tuaj yeem tsim raws li cov neeg siv khoom xav tau thiab siv tau rau txhua qhov zaus txheem thiab nrov nrog ntau yam bandwidths los ntawm DC txog 50GHz.
Lub tshuab faib hluav taws xob
Lub tshuab faib hluav taws xobyog ib lub cuab yeej uas faib ib lub teeb liab nkag mus rau hauv ob lossis ntau lub zog tso zis sib npaug
structurally muab faib ua ob pawg:
(1) Cov yam ntxwv tseem ceeb ntawm passive power divider yog: kev ua haujlwm ruaj khov, cov qauv yooj yim thiab tsis muaj suab nrov; Nws qhov tsis zoo tseem ceeb yog tias qhov poob nkag loj dhau.
(2) Lub tshuab faib fais fab nquag yog tsim los ntawm lub amplifier. Nws cov yam ntxwv tseem ceeb yog: nce thiab kev rho tawm siab. Nws cov teeb meem tseem ceeb yog suab nrov, cov qauv nyuaj thiab kev ua haujlwm tsis ruaj khov. Lub qhov tso zis ntawm lub tshuab faib fais fab muaj ob lub zog, peb lub zog, plaub lub zog, rau lub zog, yim lub zog thiab kaum ob lub zog.
Nws yog ib lub cuab yeej uas faib ib lub zog teeb liab nkag mus rau hauv ob lossis ntau txoj kab thiab tso tawm lub zog sib npaug lossis tsis sib npaug. Nyob rau hauv lem, nws tuaj yeem ua ntau lub zog teeb liab rau hauv ib qho zis. Lub sijhawm no, nws kuj tseem tuaj yeem hu ua combiner. Yuav tsum muaj qee qib kev sib cais ntawm cov qhov tso zis ntawm lub zog faib hluav taws xob. Raws li cov zis, lub zog faib hluav taws xob feem ntau yog faib ua ib qho hauv ob (ib qho nkag thiab ob qho tso zis), ib qho hauv peb (ib qho nkag thiab peb qhov tso zis), thiab lwm yam. Cov kev cai tseem ceeb ntawm lub zog faib hluav taws xob yog lub zog poob (xws li kev poob ntxig, kev faib tawm poob thiab kev cuam tshuam poob), voltage sawv nthwv dej piv ntawm txhua qhov chaw nres nkoj, kev sib cais ntawm cov chaw faib hluav taws xob, qhov sib npaug ntawm qhov siab, qhov sib npaug ntawm theem, lub peev xwm fais fab thiab bandwidth, thiab lwm yam.
Cov cim qhia txog kev siv tshuab
Cov ntsuas kev siv tshuab ntawm lub zog faib hluav taws xob suav nrog ntau zaus, lub zog nqa, kev faib tawm poob ntawm lub voj voog tseem ceeb mus rau ceg, kev nkag mus poob ntawm cov tswv yim thiab cov zis, kev sib cais ntawm cov chaw nres nkoj ceg, qhov sib piv ntawm lub zog sawv ntsug ntawm txhua qhov chaw nres nkoj, thiab lwm yam.
1. Qhov ntau zaus: Qhov no yog qhov ua haujlwm ntawm ntau yam RF / microwave circuits. Cov qauv tsim ntawm lub zog faib hluav taws xob muaj feem cuam tshuam nrog qhov zaus ua haujlwm. Qhov zaus ua haujlwm ntawm lub zog faib hluav taws xob yuav tsum tau txhais ua ntej qhov kev tsim qauv hauv qab no tuaj yeem ua tiav.
2. Lub zog nqa: hauv lub tshuab faib hluav taws xob / tshuab ua hluav taws xob muaj zog siab, lub zog siab tshaj plaws uas lub voj voog tuaj yeem nqa tau yog qhov ntsuas tseem ceeb, uas txiav txim siab seb hom kab xa hluav taws xob twg tuaj yeem siv los ua tiav txoj haujlwm tsim. Feem ntau, qhov kev txiav txim ntawm lub zog nqa los ntawm kab xa hluav taws xob los ntawm me mus rau loj yog kab microstrip, kab stripline, kab coaxial, kab cua stripline thiab kab cua coaxial. Kab twg yuav tsum tau xaiv raws li txoj haujlwm tsim.
3. Kev poob ntawm kev faib tawm: qhov kev poob ntawm kev faib tawm ntawm lub voj voog tseem ceeb mus rau lub voj voog ceg yog qhov tseem ceeb cuam tshuam nrog qhov piv ntawm kev faib tawm fais fab ntawm tus faib hluav taws xob. Piv txwv li, qhov kev poob ntawm kev faib tawm ntawm ob lub faib hluav taws xob sib npaug yog 3dB thiab ntawm plaub lub faib hluav taws xob sib npaug yog 6dB.
4. Kev poob ntawm kev ntxig: qhov kev poob ntawm kev ntxig ntawm cov tswv yim thiab cov zis yog tshwm sim los ntawm qhov tsis zoo ntawm dielectric lossis tus neeg coj ntawm txoj kab xa xov (xws li kab microstrip) thiab xav txog qhov piv ntawm nthwv dej sawv ntawm qhov kawg ntawm qhov nkag.
5. Qib kev rho tawm: qib kev rho tawm ntawm cov chaw nres nkoj ceg yog lwm qhov tseem ceeb ntawm kev faib hluav taws xob. Yog tias lub zog nkag los ntawm txhua qhov chaw nres nkoj ceg tsuas yog tuaj yeem tso tawm los ntawm qhov chaw nres nkoj tseem ceeb thiab yuav tsum tsis txhob tso tawm los ntawm lwm ceg, nws yuav tsum muaj kev rho tawm txaus ntawm cov ceg.
6. VSWR: qhov me dua VSWR ntawm txhua qhov chaw nres nkoj, qhov zoo dua.

Peb kuj tseem tuaj yeem kho cov khoom siv rf passive raws li koj xav tau. Koj tuaj yeem nkag mus rau nplooj ntawv kho kom raug kom muab cov lus qhia koj xav tau.
