• Ngokwahlula isignali ibe ziisignali ezimbini zobude obulinganayo kunye nenqanaba elingaguqukiyo lama-90 okanye i-180°.
• Ukudibanisa iquadrature okanye ukwenza ukushwankathela/ukudibanisa umahluko.
Intshayelelo
Ii-Couplers kunye nee-hybrids zizixhobo apho iintambo ezimbini zothumelo zidlula kufutshane ngokwaneleyo enye kwenye ukuze amandla asasazeke kumgca omnye ukuya komnye umgca. I-3dB 90 ° okanye i-180 ° hybrid yahlula isignali yegalelo kwiimveliso ezimbini ezilinganayo ze-amplitude. I-coupler eyalathiswayo iqhele ukwahlula isiginali yegalelo kwiziphumo ezibini ezingalinganiyo ze-amplitude. Esi sigama esithi "directional coupler", "90 ° hybrid", kunye "180 ° hybrid" sisekelwe kwingqungquthela. Nangona kunjalo, i-90 ° kunye ne-180 ° i-hybrids inokucingelwa njenge-3 dB i-coupleal couplers. Ngaphandle koku kufana, iiparamitha ezisetyenziselwa ukuchaza ukuhamba komqondiso kwii-couplers ezibhekiselele kunye nesicelo, ekusetyenzisweni okwenyani, sahluke ngokwaneleyo ekuqinisekiseni ukuqwalaselwa okwahlukileyo.
180 ° Hybrids Inkcazo esebenzayo
A 180 ° hybrid sisixhobo reciprocal ezine-port ebonelela ezimbini ezilinganayo amplitude in-inqanaba imiqondiso xa kondliwa ukusuka sum yayo port (S) kunye nemiqondiso ezimbini ezilinganayo amplitude 180 ° ngaphandle-kwesigaba xa kondliwa ukusuka kwizibuko layo umahluko (D). Ngokuchaseneyo, igalelo leesiginali kumazibuko C kunye no-D ziya kongeza kwi-sum port (B) kwaye umahluko weempawu ezimbini ziya kubonakala kwi-port umahluko (A). Umzobo 1 ngumzobo osebenzayo oza kusetyenziswa kweli nqaku ukumela i-180 ° hybrid. Izibuko B linokuqwalaselwa njengezibuko elisixa kunye nezibuko A ngumahluko wezibuko. Amazibuko A kunye no-B kunye namazibuko C kunye no-D ngababini abazimeleyo bamazibuko.
I-90 ° Hybrids okanye i-hybrid couplers ngokusisiseko i-3 dB i-couplers ye-directional apho isigaba somqondiso odibeneyo wesiphumo kunye nomqondiso wokuphuma u-90 ° ngaphandle. Ukusukela ukuba -3 dB imele isiqingatha samandla, i-3 dB coupler yahlula amandla ngokulinganayo (ngaphakathi konyamezelo oluthile) phakathi kwemveliso kunye namazibuko aphumayo adityanisiweyo. Umahluko wesigaba sama-90° phakathi kweziphumo wenza ukuba imixube ibe luncedo kuyilo lwezixhobo zombane eziguquguqukayo, izixube zeemicrowave, iimodyuli kunye nezinye iinxalenye ezininzi zemicrowave kunye neenkqubo. Umzobo 5 ubonisa idayagram yesekethe kunye netheyibhile yenyaniso eza kusetyenziswa ekucaciseni ukusebenza kweRF frequency 90° hybrid. Njengoko kunokubonwa kulo mzobo, isignali esetyenzisiweyo kuyo nayiphi na igalelo iya kubangela iimpawu ezimbini ezilinganayo ze-amplitude ezine-quadrature, okanye i-90 °, ngaphandle kwesigaba kunye nomnye. Amazibuko A kunye no-B kunye namaZibuko C kunye no-D abekwe zodwa. Njengoko bekutshiwo ngaphambili kwi-180 ° icandelo le-hybrid, izixhobo zeRF kunye ne-microwave frequency zisebenzisa iindlela ezahlukeneyo zokwakha. Nangona iimpendulo zethiyori ziyafana, indawo yezibuko kunye nendibano yahlukile. Ngezantsi, kuMzobo kukho iinguqulelo "ezinqamlezayo" kunye ne "non-crossover" ezinikezelweyo kwiifrikhwensi ze-microwave (500 MHz kunye naphezulu) kunye nesiphumo setafile yenyaniso. Imihlanganiselwa yeedigri ezingamashumi alithoba ikwabizwa ngokuba yi-quadrature hybrids kuba isigaba seziphumo ezibini sisinadi (90°) ngokwahlukeneyo. Qaphela kwakhona ukuba ayenzi nawuphi na umahluko ukuba leliphi izibuko izibuko longeniso nje ukuba ubudlelwane phakathi kwamazibuko buhleli. Oku kungenxa yokuba i-90 ° hybrids ilingana ngombane nangoomatshini malunga nee-Axes ze-X kunye ne-Y.
Si Chuan Keenlion Microwave ukhetho olukhulu lwe-3DB ibhulorho ye-hybrid kwi-narrowband kunye noqwalaselo lwe-broadband, egubungela amaza ukusuka kwi-0.5 ukuya kwi-50 GHz. Zenzelwe ukuphatha ukusuka kwi-10 ukuya kwi-30 igalelo lamandla kwi-50-ohm inkqubo yokuhambisa. Uyilo lweMicrostrip okanye lwestripline luyasetyenziswa, kwaye lulungiselelwe ukusebenza kakuhle.
Iiyunithi ziza kumgangatho kunye ne-SMA okanye i-N iziqhagamshelo zabasetyhini, okanye i-2.92mm, 2.40mm, kunye ne-1.85mm izihlanganisi zamacandelo aphezulu.
Sinokwenza ngokwezifiso i-3DB Hybrid Bridge ngokweemfuno zakho. Ungangenisa iphepha lokulungiselela ukubonelela ngeenkcukacha ozifunayo.
