sib txuas
Fais fab kev faib khoom rau faib RF teeb liab rau hauv ob txoj hauv kev faib ua feem thiab tso tawm mus rau kav hlau txais xov feeder system
Cov ntawv thov tseem ceeb
(1) Kev siv hauv logic circuit
Lub coupler tuaj yeem tsim ntau yam logic circuits. Vim tias kev tiv thaiv kev cuam tshuam thiab kev sib cais kev ua haujlwm ntawm lub coupler zoo dua li ntawm transistor, lub logic Circuit Court tsim los ntawm nws yog ntau txhim khu kev qha.
Daim ntawv thov teb thiab lub sijhawm ntawm coupler
(2) Daim ntawv thov raws li lub xeev hloov pauv
Nyob rau hauv lub switching Circuit Court, nws yog feem ntau yuav tsum tau muaj ib tug zoo hluav taws xob kev sib cais ntawm kev tswj Circuit Court thiab lub switching, uas yog ib qho nyuaj rau lub general hluav taws xob hloov, tab sis nws yog ib qho yooj yim kom paub nrog lub coupler.
(3) Kev siv rau hauv qhov hluav taws xob hluav taws xob
Thaum lub coupler yog siv nyob rau hauv lub bistable tso zis Circuit Court, qhov teeb meem ntawm kev sib cais ntawm cov zis thiab load yuav daws tau zoo vim hais tias cov LED tuaj yeem txuas rau hauv series rau hauv lub emitter Circuit Court ntawm ob lub raj.
(4) Daim ntawv thov hauv pulse amplification circuit
Couplers yog siv nyob rau hauv digital circuits rau amplify mem tes signals.
(5) Daim ntawv thov hauv linear circuit
Linear coupler yog siv nyob rau hauv linear circuit, uas muaj siab linearity thiab zoo heev hauv av hluav taws xob cais kev ua tau zoo.
(6) Kev thov rau lub sijhawm tshwj xeeb
Lub coupler kuj tseem siv tau rau hauv kev tswj hluav taws xob siab, hloov pauv hloov pauv, hloov kev sib cuag relay thiab A / D Circuit Court.
Technical ntsuas
1. Coupling degree: qhov sib txawv ncaj qha ntawm cov zis hluav taws xob los ntawm qhov chaw nres nkoj txuas thiab lub teeb liab input zog thaum lub teeb liab lub zog dhau los ntawm kev sib txuas.
2. Isolation degree: hais txog kev sib cais ntawm qhov chaw nres nkoj tso zis thiab qhov chaw sib txuas; Feem ntau, qhov ntsuas no tsuas yog siv los ntsuas microstrip coupler. Thiab nws txawv raws li qhov kev sib txuas lus: piv txwv li, 5-10db yog 18 ~ 23dB, 15dB yog 20 ~ 25dB, thiab 20dB (xws li saum toj no) yog 25 ~ 30dB; qhov kev sib cais ntawm kab noj hniav coupler yog qhov zoo heev, yog li tsis muaj qhov yuav tsum tau ua rau qhov ntsuas no.
3. Directivity: yog hais txog tus nqi ntawm qhov kev sib cais ntawm qhov chaw nres nkoj tso zis thiab qhov chaw sib txuas ntawm qhov chaw nres nkoj rho tawm tus nqi ntawm qhov coupling degree. Txij li cov kev coj ncaj ncees ntawm microstrip txo qis zuj zus nrog kev nce qib ntawm kev sib txuas, yog qhov tsis muaj kev ncaj ncees siab dua 30dB, yog li tsis muaj qhov ntsuas qhov xav tau rau microstrip coupler. Kev coj ncaj qha ntawm kab noj hniav feem ntau yog 17 ~ 19dB ntawm 1700 ~ 2200MHz, 824 ~ 960MHz: 18 ~ 22dB.
4. Cov txheej txheem suav: directivity = cais - coupling.
5. Insertion poob: yog hais txog tus nqi tau los ntawm kev rho tawm tus nqi ntawm kev faib tawm los ntawm kev txo cov teeb liab hluav taws xob los ntawm lub teeb liab lub zog los ntawm lub coupler mus rau qhov tso zis. Feem ntau, qhov poob ntawm microstrip coupler sib txawv raws li qhov kev sib txuas. Feem ntau, nws yog 0.35 ~ 0.5dB rau tsawg dua 10dB thiab 0.2 ~ 0.5dB rau ntau tshaj 10dB.
6. Input / output sawv yoj piv: hais txog qhov sib txuam ntawm cov tswv yim / tso tawm cov chaw nres nkoj, thiab cov kev xav tau ntawm txhua qhov chaw nres nkoj feem ntau yog 1.2 ~ 1.4;
7. Lub hwj chim kam rau ua: yog hais txog lub siab tshaj plaws ua hauj lwm lub hwj chim kam rau ua kom dhau los ntawm lub coupler no ntev (tsis muaj kev puas tsuaj). Feem ntau, qhov nruab nrab lub zog ntawm microstrip coupler yog 30 ~ 70W, thiab cov kab noj hniav yog 100 ~ 200W.
8. Ntau zaus: feem ntau, qhov nominal zaus yog 800 ~ 2200MHz. Qhov tseeb, qhov xav tau zaus band yog 824-960MHz ntxiv rau 1710 ~ 2200MHz. Qhov nruab nrab zaus band tsis muaj.
9. Nyob rau hauv band Flatness: yog hais txog qhov sib txawv ntawm qhov siab tshaj plaws thiab qhov tsawg kawg nkaus coupling degree nyob rau hauv tag nrho cov muaj zaus band. Microstrip feem ntau yog 0.5 ~ 0.2db. Kab noj hniav: txij li thaum lub coupling degree yog ib tug nkhaus, tsis muaj xws li yuav tsum tau.
Peb kuj tuaj yeem kho cov rf passive Cheebtsam raws li koj xav tau. Koj tuaj yeem nkag mus rau nplooj ntawv customization los muab cov kev qhia tshwj xeeb uas koj xav tau.
