RF Duplexer
Lub cavity duplexer yog ib hom duplexer tshwj xeeb uas siv rau hauv cov kab ke sib txuas lus wireless los cais cov teeb liab xa thiab tau txais hauv thaj chaw zaus. Lub cavity duplexer muaj ib khub resonant cavities, txhua tus muaj lub luag haujlwm tshwj xeeb rau kev sib txuas lus hauv ib qho kev taw qhia.
Lub hauv paus ntsiab lus ua haujlwm ntawm lub cavity duplexer yog raws li kev xaiv zaus, uas siv ib lub resonant cavity tshwj xeeb los xa cov teeb liab hauv qhov ntau zaus. Tshwj xeeb, thaum lub teeb liab raug xa mus rau hauv lub cavity duplexer, nws raug xa mus rau ib lub resonant cavity tshwj xeeb thiab amplified thiab xa mus rau ntawm qhov zaus resonant ntawm lub cavity ntawd. Tib lub sijhawm, lub teeb liab tau txais tseem nyob hauv lwm lub resonant cavity thiab yuav tsis raug xa lossis cuam tshuam nrog.

RFTYT RF Hybrid Combiner Kev sib xyaw ua ke ntawm cov teeb liab thiab kev ua kom nrov
RF hybrid combiner, ua ib qho tseem ceeb ntawm cov kab ke sib txuas lus wireless thiab radar thiab lwm yam khoom siv hluav taws xob RF, tau siv dav. Nws lub luag haujlwm tseem ceeb yog sib xyaw cov teeb liab RF thiab tso tawm cov teeb liab sib xyaw tshiab. RF Hybrid Combiner muaj cov yam ntxwv ntawm kev poob qis, nthwv dej me me, kev rho tawm siab, qhov loj me thiab qhov sib npaug zoo, thiab ntau qhov nkag thiab tawm.
RF Hybrid Combiner yog nws lub peev xwm los ua kom tiav kev sib cais ntawm cov teeb liab nkag. Qhov no txhais tau tias ob lub teeb liab nkag yuav tsis cuam tshuam rau ib leeg. Qhov kev sib cais no tseem ceeb heev rau cov kab ke sib txuas lus wireless thiab RF lub zog amplifiers, vim nws tuaj yeem tiv thaiv kev cuam tshuam ntawm cov teeb liab thiab kev poob hluav taws xob.

RFTYT Low PIM Couplers Ua ke lossis Qhib Circuit
Tus coupler intermodulation qis yog ib lub cuab yeej siv dav hauv cov kab ke sib txuas lus wireless los txo qhov kev cuam tshuam intermodulation hauv cov khoom siv wireless. Intermodulation distortion yog hais txog qhov xwm txheej uas ntau lub teeb liab hla dhau lub kaw lus nonlinear tib lub sijhawm, ua rau muaj cov khoom siv zaus tsis muaj uas cuam tshuam rau lwm cov khoom siv zaus, ua rau kev ua haujlwm ntawm lub kaw lus wireless txo qis.
Hauv cov kab ke sib txuas lus wireless, cov couplers intermodulation qis feem ntau yog siv los cais cov teeb liab muaj zog siab los ntawm cov teeb liab tso zis kom txo qhov kev cuam tshuam ntawm intermodulation.

RF Coupler (3dB, 10dB, 20dB, 30dB)
Ib lub coupler yog ib qho khoom siv RF microwave uas siv ntau zaus los faib cov teeb liab nkag mus rau ntau qhov chaw tso zis, nrog rau cov teeb liab tso zis los ntawm txhua qhov chaw nres nkoj muaj qhov sib txawv thiab theem sib txawv. Nws yog siv dav hauv cov kab ke sib txuas lus wireless, radar systems, microwave ntsuas khoom siv, thiab lwm yam teb.
Cov couplers muaj peev xwm muab faib ua ob hom raws li lawv cov qauv: microstrip thiab cavity. Sab hauv ntawm microstrip coupler feem ntau yog tsim los ntawm lub network coupling uas muaj ob txoj kab microstrip, thaum sab hauv ntawm lub cavity coupler tsuas yog tsim los ntawm ob daim hlau.
