Emkhakheni wokudlulisa isignali ye-RF kanye ne-microwave, ngaphezu kokudluliswa kwesignali okungenantambo, iningi lazo lidinga izintambo zokudlulisa ukuze kuqhutshwe isignali, nemigqa ye-coaxial namagagasi asetshenziswa kakhulu ukudlulisa amandla e-microwave RF.
Imigqa yokudlulisa ye-Waveguide inezinzuzo zokulahleka kwe-conductor ephansi kanye ne-dielectric, umthamo wamandla amakhulu, akukho ukulahlekelwa kwemisebe, isakhiwo esilula, nokukhiqiza okulula.Amagagasi asetshenziswa kakhulu ahlanganisa unxande, oyindilinga, i-single ridged, i-double ridged, ne-elliptical.Njengamanje, ama-waveguides asetshenziswa kakhulu amagagasi angama-rectangular.
Enqubweni yokusetshenziswa kwamadivayisi we-waveguide, amadivaysi amaningi ngokuvamile adinga ukuxhunywa ngokuhambisanayo, futhi ukuxhumana phakathi kwamadivayisi aseduze we-waveguide kuvame ukufinyelelwa ngokuxhumeka okuhambisanayo kwama-flange.
Njengezixhumi ze-coaxial ze-RF, ama-waveguides avamile nama-flange nawo amisiwe emhlabeni jikelele.Ngethebula elingezansi, ungabuza amagama ajwayelekile ahambisanayo nosayizi bamagagasi abahlukahlukene abawunxande.
Ukusetshenziswa kwe-Waveguide Coaxial Converter
Ngokufanayo, imigqa ye-coaxial futhi imigqa yokudlulisela evame ukusetshenziswa kakhulu kubunjiniyela be-microwave kanye nefrikhwensi yomsakazo, enezici ze-broadband ezingasebenza kusukela kumanje oqondile kuya kuma-millimeter wave band, noma ngaphezulu kwalokho.Imigqa yokudlulisa i-coaxial isetshenziswe kabanzi kuzo zombili izinhlelo ze-microwave nezingxenye ze-microwave.
Kunomehluko omkhulu ngosayizi, izinto ezibonakalayo, kanye nezici zokudlulisela phakathi kwemigqa yokudlulisela i-coaxial ne-waveguide.Kodwa-ke, ngenxa yohlu olubanzi lwezinhlelo zabo zokusebenza, onjiniyela be-RF bavame ukuhlangana nezimo lapho imigqa emibili yokudlulisela idinga ukuxhunywa, edinga iziguquli ze-coaxial waveguide.
Iziguquli ze-coaxial waveguide zingamadivayisi abalulekile emishinini ye-microwave, isilinganiso se-microwave, izinhlelo ze-microwave, kanye nobunjiniyela.Izindlela zabo zokuguqula ngokuyinhloko zihlanganisa ukuhlanganisa imbobo encane, ukuhlanganisa i-probe, ukuguqulwa komugqa ophelile, nokuguqulwa kwe-ridge waveguide;I-coaxial probe coupling iyindlela yokuguqula esetshenziswa kakhulu phakathi kwabo.
Isiguquli se-waveguide coaxial ikakhulukazi siqukethe isiguquli sokuqala, isiguquli sesibili, kanye ne-flange, nezingxenye ezintathu ezixhunywe ngokulandelana.Ngokuvamile kukhona iziguquli ze-orthogonal ze-90 ° waveguide coaxial kanye neziguquli ze-coaxial ezingu-180 ° ezinqanyulwe.Isiguquli se-coaxial waveguide sinezici zebhendi yefrikhwensi ebanzi, ukulahleka kokufakwa okuphansi, namagagasi amancane okuma.I-bandwidth yomugqa we-coaxial kanye ne-waveguide ibanzi uma idluliswa ngokulandelana, futhi umkhawulokudonsa ngemva kokuxhuma uncike ekufanisweni kokuvinjelwa kwesici kwe-coaxial waveguide.
Ukuguqulwa kwe-coaxial waveguide kuvame ukusetshenziswa ezinhlelweni eziningi ze-microwave, njengama-antenna, ama-transmitters, izamukeli, kanye namadivayisi we-carrier terminal, angasetshenziswa kabanzi kwezokuxhumana ngesathelayithi, i-radar, ukuxhumana okungenantambo, i-microwave yezimboni, ukuhlola ama-microwave nezinhlelo zokulinganisa, izinhlelo ze-microwave zezokwelapha. , njll.
