Lub 3dB hybrid coupler yog ib qho khoom siv passive uas faib cov teeb liab tawm tswv yim rau hauv ob qho tib si amplitude signals nrog 90 ° theem sib txawv. Tam sim no, feem ntau yog 800-2500MHz wide-band 3dB hybrid couplers, thiab 3dB Hybrid couplers uas yog siv los ua ke cov teeb liab ntawm tib zaus. Nta: Muab GSM, DCS, DTV, WLAN, WCDMA, thiab CDMA2000. CDMA800 thiab lwm yam kev taw qhia rau hauv ib lossis ntau txoj kev thiab pub rau lawv rau hauv kev faib khoom; 3dB Hybrid Coupler nrog ib zaus thiab ntau zaus ua ke nrog cov kev nkag qis qis, me me hauv-band hloov pauv, thiab sawv tsis muaj me me, kev sib cais siab; muaj peev xwm loj; Kev ntseeg siab (tiv thaiv kev vibration, tiv thaiv kev poob siab), kev kub siab ua haujlwm, 3dB Hybrid Coupler corrosion kuj, thiab tsis muaj dej.
3dB hybrid coupler kev taw qhia: 3dB hybrid coupler tseem hu ua tib zaus sib txuas, 3dB Hybrid Coupler nws tuaj yeem txuas ntxiv coj mus kuaj lub zog xa mus rau qee qhov kev taw qhia ntawm cov kab sib txuas, 3dB Hybrid Coupler thiab tuaj yeem faib cov teeb liab tawm tswv yim rau hauv ob qho tib si amplitudes nrog. 90 ° theem tsis zoo teeb liab. Nws yog tsuas yog siv rau ntau lub teeb liab ua ke los txhim kho kev siv tus nqi ntawm cov khoom tso tawm. Nws yog dav siv nyob rau hauv cov kev pab them nqi sab hauv tsev rau kev sib txuas ntawm lub hauv paus chaw nres tsheb teeb liab. Nws muaj txiaj ntsig zoo rau qhov chaw no.
3dB choj siv: Qhov kev poob ntawm tus choj 3dB yog 3.2, qhov kev sib cais kuj tseem yog 25, thiab qhov sawv nthwv dej yog qhov nruab nrab. Tab sis muaj ob qhov chaw tso zis, piv txwv li, 3dB Hybrid Coupler ob lub tswv yim 30 tso zis yog ob 27. Qhov chaw nres nkoj ntawm 3dB choj kuj tuaj yeem teeb tsa, ob lub tswv yim thiab ib qho tso zis, ib qho kev tawm tswv yim thiab ob qhov tso zis, 3dB Hybrid Coupler ob input thiab ob qhov tso zis yog tiag tiag ua tau, ib tug ntxiv chaw nres nkoj yog kev cob cog rua Cia li thauj ib tug load nrog txaus lub hwj chim. Yog hais tias lub load tsis txuas, 3dB hybrid coupler yuav raug txiav tawm ntawm lub Hoobkas, uas tsis muaj kev cuam tshuam zoo li lwm qhov load. Txawm li cas los xij, thaum sawv ntsug yoj piv yog siab, 3dB Hybrid Coupler tsuas yog siv tau 3dB. Tsis tas li ntawd, lub zog tiv thaiv ntawm lub cuab yeej yuav tsum tau txiav txim siab.
Raws li cov neeg tsim khoom ntawmRF passive Cheebtsam, peb tuaj yeem tsim tshwj xeeb tsim hluav taws xob faib hluav taws xob, cov khoom sib txuas, thiab cov sib txuas ua ke raws li koj qhov kev daws teeb meem, yog li vam tias peb tuaj yeem pab txhawb koj txhua lub sijhawm.
