Lub Wilkinson lub zog faib hluav taws xob yog qhov sib faib rov ua haujlwm uas siv ob, sib npaug, tsis sib txuas hauv peb lub hlis twg-yav dhau los hloov kab hloov pauv. Kev siv cov kab sib kis ua rau Wilkinson divider yooj yim los siv siv cov qauv luam tawm cov kab sib kis. Qhov ntev ntawm cov kab sib kis feem ntau txwv qhov ntau zaus ntawm Wilkinson divider rau zaus tshaj 500 MHz. Lub resistor nruab nrab ntawm cov chaw tso zis tso cai rau lawv muaj qhov sib txuam impedances thaum tseem muab kev sib cais. Vim tias cov chaw nres nkoj tso zis muaj cov cim ntawm tib lub amplitude thiab theem, tsis muaj qhov hluav taws xob hla lub resistor, yog li tsis muaj tam sim no ntws thiab cov resistor tsis dissipate ib lub zog.
Fais fab faib
Lub zog faib hluav taws xob muaj ib lub teeb liab tawm tswv yim thiab ob lossis ntau qhov tso zis tawm. Cov teeb liab tso zis muaj lub hwj chim theem uas yog 1 / N lub input fais fab theem qhov twg N yog tus naj npawb ntawm outputs nyob rau hauv lub divider. Cov teeb liab ntawm cov zis, nyob rau hauv ntau hom kev faib hluav taws xob, yog nyob rau theem. Muaj tshwj xeeb fais fab faib uas muab kev tswj theem hloov ntawm cov zis. Feem ntau RF daim ntawv thov rau lub zog faib hluav taws xob, raws li tau hais dhau los, coj ib qho chaw RF rau ntau yam khoom siv (Daim duab 1).
Daim duab ntawm RF qhov chaw qhia rau ntau yam khoom siv
Daim duab 1: Fais fab kev faib hluav taws xob yog siv los faib cov teeb liab RF rau ntau yam khoom siv xws li nyob rau hauv lub kav hlau txais xov theem theem lossis hauv plaub fab demodulator.
Qhov piv txwv yog lub kav hlau txais xov phased array qhov twg RF qhov chaw yog sib cais ntawm ob lub kav hlau txais xov. Kav hlau txais xov ntawm hom classicically muaj ob mus rau yim lossis ntau lub ntsiab lus, txhua tus uas tau tsav los ntawm lub zog faib tawm qhov chaw nres nkoj. Phase shifters feem ntau yog sab nraud rau qhov sib faib kom tso cai rau kev tswj xyuas hluav taws xob los tswj tus qauv kav hlau txais xov.
Lub zog faib hluav taws xob tuaj yeem khiav "rov qab" kom ntau qhov kev tawm tswv yim tuaj yeem ua ke rau hauv ib qho kev tso zis ua rau nws lub zog sib txuas. Hauv kev sib xyaw ua ke cov khoom siv no muaj peev xwm ua tau zoo vector ntxiv lossis rho tawm cov cim raws li lawv qhov amplitude thiab theem qhov tseem ceeb.
• Fais fab faib tuaj yeem siv los ua cov sib txuas lossis sib cais
• Wilkinson thiab High isolation power dividers muab kev sib cais siab, thaiv teeb liab sib tham ntawm cov chaw nres nkoj tso zis
• Kev nkag qis thiab rov qab poob
• Wilkinson thiab resistive power dividers muab zoo heev (<0.5dB) amplitude thiab (<3°) theem sib npaug
• Multi-octave daws los ntawm DC mus rau 50 GHz
Kawm paub ntau ntxiv txog Power Dividers
Raws li lub npe qhia, RF / microwave fais fab faib yuav faib cov teeb liab tawm tswv yim rau hauv ob qhov sib npaug thiab zoo ib yam (piv txwv li hauv-theem) cov cim. Nws kuj tseem tuaj yeem siv los ua lub zog sib txuas, qhov chaw nres nkoj feem ntau yog cov khoom tso tawm thiab ob lub zog sib npaug sib npaug siv los ua cov khoom siv. Cov ntsiab lus tseem ceeb thaum siv los ua lub zog faib hluav taws xob muaj xws li qhov poob qis, rov qab poob, thiab amplitude thiab theem sib npaug ntawm caj npab. Rau lub zog sib txuas ntawm cov teeb liab tsis sib xws, xws li thaum ua qhov kev ntsuam xyuas qhov tseeb intermodulation distortion (IMD) zoo li IP2 thiab IP3, qhov tshwj xeeb tseem ceeb tshaj plaws yog kev sib cais ntawm cov chaw nres nkoj nkag.
Muaj peb yam tseem ceeb ntawm RF fais fab faib thiab RF fais fab sib txuas: 0º, 90 º hybrid, thiab 180 º hybrid. Zero-degree RF dividers faib cov teeb liab tawm tswv yim rau hauv ob lossis ntau qhov tso zis tawm uas muaj qhov sib npaug ntawm ob qho tib si amplitude thiab theem. Zero-degree RF combiners koom nrog ntau lub tswv yim tawm tswv yim los muab ib qho tso zis. Thaum xaiv 0 º dividers, lub zog faib faib yog ib qho tseem ceeb tshwj xeeb los xav txog. Qhov parameter no yog tus naj npawb ntawm cov khoom tawm ntawm lub cuab yeej, lossis tus naj npawb ntawm txoj hauv kev cov teeb liab tawm tswv yim muab faib rau ntawm cov zis. Cov kev xaiv muaj xws li 2, 3, 4, 5, 6, 7, 8, 9, 12, 16, 32, 48, thiab 64-txoj kev.
RF fais fab splitters / dividersyog passive RF / microwave Cheebtsam siv rau splitting (los yog faib) microwave signals. Sichuan Keenlion Microwave Technology CO., Ltd lub zog splitters suav nrog 2-txoj kev, 3-txoj kev, 4-txoj kev, 6-txoj kev, 8-txoj kev thiab mus txog 48-txoj kev qauv rau 50 Ohm thiab 75 Ohm systems, nrog DC-dhau thiab DC-thaiv, hauv coaxial, nto mount, thiab MMIC tuag hom. Peb cov coaxial splitters muaj nrog SMA, N-Type, F-Type, BNC, 2.92mm thiab 2.4mm connectors. Xaiv los ntawm ntau tshaj 100 qauv hauv Tshuag nrog ntau zaus txog 50
GHz, lub zog tuav mus txog 200W, tsis tshua muaj qhov tsis zoo, kev sib cais siab, thiab zoo heev amplitude unbalance thiab theem tsis sib npaug.
