3dB Hybrid Coupler

I-3dB i-coupler ye-hybrid sisixhobo esahlula i-input signal kwiimpawu ezimbini ezilinganayo ze-amplitude kunye ne-90 ° umehluko wesigaba. Okwangoku, kukho ikakhulu i-800-2500MHz ebanzi-band ye-3dB hybrid couplers, kunye ne-3dB Hybrid couplers ezisetyenziselwa ukudibanisa imiqondiso yefrikhwensi efanayo. Iimpawu: Dibanisa i-GSM, i-DCS, i-DTV, i-WLAN, i-WCDMA, kunye ne-CDMA2000. I-CDMA800 kunye nezinye izibonakaliso kwitshaneli enye okanye ngaphezulu kwaye izondla kwinkqubo yokusasazwa;I-3dB Hybrid Coupler ene-single-frequency kunye ne-multi-frequency edibeneyo ishaneli kunye nelahleko ephantsi yokufaka, ukuguquguquka okuncinci kwi-band, kunye namaza amileyo Amancinci, aphezulu aphezulu; amandla amakhulu; ukuthembeka okuphezulu (i-anti-vibration, anti-shock), ukumelana nobushushu obuphezulu, i-3dB Hybrid Coupler resistance corrosion, kunye nokungangeni kwamanzi.

I-3dB hybrid coupler intshayelelo: I-3dB hybrid coupler ikwabizwa ngokuba sisidibanisi esifanayo, i-3dB Hybrid Coupler inokuqhubeka nesampulu yamandla othumelo kwicala elithile lomgca wothumelo, i-3dB Hybrid Coupler kwaye inokwahlula isiginali yegalelo ibe ngama-amplitudes amabini alinganayo. 90° isigaba Umqondiso ombi. Isetyenziselwa ikakhulu ukudibanisa iisignali ezininzi ukuphucula izinga lokusetyenziswa kweempawu zemveliso. Isetyenziswa ngokubanzi kwinkqubo yokugubungela yangaphakathi yokudibanisa imiqondiso yesikhululo sesiseko. Inefuthe elihle kule ndawo.

Ukusetyenziswa kwebhuloho ye-3dB: Ilahleko yokufakwa kwebhuloho ye-3dB yi-3.2, i-isolation nayo i-25, kwaye i-wave wave iphakathi. Kodwa kukho izibuko ezimbini zokuphuma, umzekelo, i-3dB Hybrid Coupler igalelo ezimbini ze-30 imveliso ezimbini 27. I-port yemveliso yebhulorho ye-3dB inokusetwa ngokungenasizathu, igalelo ezimbini kunye nemveliso enye, igalelo elinye kunye nemveliso emibini, i-3dB Hybrid Coupler ezimbini. igalelo kunye neemveliso ezimbini ziyenzeka ngokwenene, elinye izibuko lidityanisiwe Layisha nje umthwalo ngamandla awoneleyo. Ukuba umthwalo awuxhunyiwe, i-3dB hybrid coupler iya kunqunyulwa kumzi-mveliso, ongenayo impembelelo efana nomnye umthwalo. Nangona kunjalo, xa umlinganiselo wamaza omileyo uphezulu, i-3dB Hybrid Coupler kuphela yi-3dB enokusetyenziswa. Ukongeza, amandla okumelana nesixhobo nawo kufuneka aqwalaselwe.
Njengomvelisi weAmalungu e-RF asebenzayo, singayila ngokukodwa izahluli zamandla, ii-couplers, kunye nezihlanganisi njengesisombululo sakho, ke sinethemba lokuba sinokukuxhasa nangaliphi na ixesha.
