11 Txoj Kev Fais Fab Faib / Combiners RF Microwave Millimeter High Power Microstrip Resistive Broadband
Cov qauv ntawm 11-txoj kev RF fais fab faib / sib txuas
Cov qauv ntawm 11-txoj kev faib hluav taws xob siab / sib txuas feem ntau yog tsim los ntawm qhov kawg nkag, qhov kawg tso zis, qhov kawg cuam tshuam, qhov chaw resonant, thiab cov khoom siv hluav taws xob. Lub hauv paus ntsiab lus ua haujlwm ntawm lub zog faib hluav taws xob yog faib lub teeb liab nkag mus rau hauv ob lossis ntau lub teeb liab tso zis, nrog txhua lub teeb liab tso zis muaj lub zog sib npaug. Lub reflector cuam tshuam lub teeb liab nkag mus rau hauv qhov chaw resonant, uas faib lub teeb liab nkag mus rau hauv ob lossis ntau lub teeb liab tso zis, txhua tus muaj lub zog sib npaug.
Lub 11 channel fais fab faib/sib txuas tuaj yeem ua tau raws li cov kev cai tshwj xeeb rau kev sib cais lossis sib txuas cov ntaub ntawv teeb liab ntawm 11 inputs lossis outputs.
Cov cim qhia tseem ceeb ntawm 11-txoj kev resistor fais fab faib / combiner suav nrog impedance matching, insertion loss, isolation degree, thiab lwm yam.
Nta:
1. Kev sib phim impedance: Los ntawm kev faib cov khoom parameter (microstrip lines), qhov teeb meem ntawm impedance mismatch thaum lub sijhawm xa hluav taws xob tau daws, yog li cov nqi input thiab output impedance ntawm lub zog faib / combiner yuav tsum ze li sai tau kom txo cov teeb liab distortion.
2. Kev poob qis ntawm kev ntxig: Los ntawm kev tshuaj xyuas cov ntaub ntawv ntawm lub zog faib hluav taws xob, ua kom zoo dua cov txheej txheem tsim khoom, thiab txo qhov poob ntawm lub zog faib hluav taws xob; Los ntawm kev xaiv cov qauv network thiab cov yam ntxwv ntawm lub voj voog tsim nyog, qhov kev faib hluav taws xob poob ntawm lub zog faib hluav taws xob tuaj yeem txo qis. Yog li ua tiav kev faib hluav taws xob sib xws thiab qhov poob tsawg kawg nkaus.
3. Kev rho tawm siab: Los ntawm kev ua kom muaj kev tiv thaiv kev rho tawm ntau ntxiv, cov teeb liab cuam tshuam ntawm cov chaw nres nkoj tso zis raug nqus, thiab kev tshem tawm cov teeb liab ntawm cov chaw nres nkoj tso zis raug nce ntxiv, ua rau muaj kev rho tawm siab.
Daim Ntawv Thov:
1. Lub tshuab faib/sib txuas fais fab microwave 11-txoj kev siv tau los xa ib lub teeb liab mus rau ntau lub antennas lossis receivers, lossis faib ib lub teeb liab ua ntau lub teeb liab sib npaug.
2. Ib qho 11-txoj kev millimeter nthwv zog faib/sib txuas siv tau rau hauv cov khoom siv hluav taws xob, ncaj qha txiav txim siab qhov ua tau zoo, cov yam ntxwv ntawm qhov zaus, thiab lwm yam kev ua tau zoo ntawm cov khoom siv hluav taws xob.
Qualwaveinc. muab 11-txoj kev broadband fais fab faib/sib txuas hauv qhov zaus ntawm DC txog 1GHz, nrog lub zog txog li 2W.
