I-3dB Hybrid Coupler

I-3dB hybrid coupler iyisisetshenziswa esingenzi lutho esihlukanisa isignali yokufaka ibe amasignali amabili alinganayo e-amplitude anomehluko wesigaba esingu-90°. Njengamanje, kunama-couplers angama-3dB angama-800-2500MHz ama-wide-band 3dB, kanye nama-couplers angu-3dB Hybrid asetshenziselwa ukuhlanganisa amasignali wefrikhwensi efanayo. Izici: Hlanganisa i-GSM, i-DCS, i-DTV, i-WLAN, i-WCDMA, ne-CDMA2000. I-CDMA800 kanye nezinye izimpawu zibe yisiteshi esisodwa noma ngaphezulu futhi ziphakele ohlelweni lokusabalalisa;I-3dB Hybrid Coupler eneziteshi ezihlanganisiwe ze-single-frequency kanye ne-multi-frequency enokulahlekelwa okuphansi kokufaka, ukushintshashintsha okuncane kwe-band, namagagasi amile Ukuhlukaniswa okuncane, okuphezulu; amandla amakhulu; ukuthembeka okuphezulu (anti-vibration, anti-shock), ukumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala kwe-3dB Hybrid Coupler, nokungangeni kwamanzi.

Isingeniso se-3dB hybrid coupler: I-3dB hybrid coupler ibizwa nangokuthi i-frequency combiner efanayo, i-3dB Hybrid Coupler ingaqhubeka nokusampula amandla okudlulisela ohlangothini oluthile lwelayini yokudlulisela, i-3dB Hybrid Coupler futhi ingahlukanisa isignali yokufaka ibe ama-amplitude amabili alinganayo nge 90° isigaba Isignali embi. Isetshenziselwa ikakhulukazi inhlanganisela yamasignali amaningi ukuze kuthuthukiswe izinga lokusebenzisa amasignali okukhiphayo. Isetshenziswa kabanzi ohlelweni lokumboza lwangaphakathi lokuhlanganiswa kwamasignali esiteshi sesisekelo. Kunomthelela omuhle kule ndawo.

Ukusetshenziswa kwebhuloho le-3dB: Ukulahlekelwa kokufaka kwebhuloho le-3dB ngu-3.2, ukuhlukaniswa nakho kungu-25, futhi igagasi elimile liyisilinganiso. Kodwa kunezimbobo zokuphuma ezimbili, isibonelo, i-3dB Hybrid Coupler okukhiphayo okubili okungu-30 okubili okungu-27. Imbobo yokuphuma yebhuloho le-3dB nayo ingasethwa ngokungafanele, okokufaka okubili nokukodwa okukhiphayo, okokufaka okukodwa nokubili okukhiphayo, i-3dB Hybrid Coupler okubili. okokufaka nokubili okukhiphayo kungenzeka ngempela, imbobo eyodwa ngaphezulu ixhunyiwe Vele ulayishe umthwalo ngamandla anele. Uma umthwalo ungaxhumekile, i-3dB hybrid coupler izonqanyulwa embonini, engenawo umthelela ofana nomunye umthwalo. Kodwa-ke, lapho isilinganiso samagagasi esimile siphezulu, i-3dB Hybrid Coupler kuphela i-3dB engasetshenziswa. Ngaphezu kwalokho, amandla okumelana nedivayisi nawo kufanele acatshangelwe.
Njengomkhiqizi weIzingxenye ze-RF passive, singaklama ngokukhethekile izihlukanisi zamandla, izixhumi, nezihlanganisi njengesixazululo sakho, ngakho sithemba ukuthi singakusekela noma nini.
