I-Dual Directional Crossguide Coupler, 9~9.5GHz, 40dB, FBP100, SMA

I-dual directional crossguide coupler iyisisetshenziswa sokungenzi lutho esinembe kakhulu esisetshenziswa ezinhlelweni ze-microwave RF. Umsebenzi wayo oyinhloko uwukusampula ngesikhathi esisodwa futhi uhlukanise amandla akho kokubili okuya phambili (igagasi lesigameko) kanye namasiginali okubuyela emuva (amagagasi abonisiwe) esiteshini esikhulu sokudlulisa ngaphandle kokuthikameza ngokuphawulekayo ukudluliswa kwesignali eyinhloko. Le divayisi isebenzisa ukwakheka kwe-waveguide yakudala, iqinisekisa ukulahlekelwa okuphansi namandla aphezulu, kuyilapho izimbobo ezihlanganisayo zifaka ukuxhumana okujwayelekile kwe-SMA ukuze kuhlanganiswe kalula nokuhlola.

Izici Eziyinhloko:

1. Ukumbozwa kwefrikhwensi okunembile: Ibhendi yefrikhwensi yokusebenza ivala ngokuqinile i-9GHz ukuya ku-9.5GHz, ethuthukiselwe amasistimu e-X-band, ebonisa ukusabela okuphansi nokusebenza okuhle kakhulu kukagesi ngaphakathi kwalolu banga.
2. Ukuhlanganiswa okuphezulu kwe-40dB: Inikeza ukuhlanganisa okungu-40dB okunembile, okusho ukuthi ingxenye eyodwa kuphela yenkulungwane eyishumi yamandla isampula esiteshini esikhulu, okunomthelela omncane ekudluliselweni kwesignali yesistimu eyinhloko, okuyenza ifanelekele izinhlelo zokusebenza zokuqapha ezinamandla aphezulu, ezinembayo.
3. Umsebenzi wokuhlanganisa indawo ekabili: Kusetshenziswa ukwakheka "kwesiphambano", isisetshenziswa esisodwa sihlinzeka ngokuphumayo okubili okuhlangene okuzimele: okukodwa okokusampula igagasi lesigameko esiya phambili kanye nelinye ukusampula igagasi elibonisiwe elibuyela emuva. Lokhu kuthuthukisa kakhulu ukulungisa iphutha kwesistimu nokusebenza kahle kokuxilongwa kwamaphutha.
4. Idizayini esekelwe ku-Waveguide, ukusebenza okukhethekile:
Ukulahleka kokufakwa okuphansi: Isiteshi esikhulu sisebenzisa i-waveguide engunxande, eqinisekisa ukusebenza kahle kokudlulisela phambili kanye nokulahlekelwa okungokwemvelo okuncane.
Umthamo wamandla aphezulu: Iyakwazi ukumelana namazinga aphezulu aphakathi nendawo aphezulu, ihlangabezana nezidingo zezinhlelo zokusebenza zamandla aphezulu njengamasistimu e-radar.
Ukuqondisa okuphezulu nokuhlukaniswa: Ihlukanisa ngokunembile phakathi kwesigameko namagagasi abonisiwe kuyilapho icindezela ngempumelelo isignali yokuhlangana phakathi kwamachweba, iqinisekisa ubuqiniso nokunemba kwedatha eyisampula.
5. Izixhumi ze-SMA zamachweba ahlanganisiwe: Izimbobo zokukhiphayo ezihlanganisiwe zifakwe ukuxhumana okujwayelekile kwabesifazane be-SMA, okuvumela ukuxhumeka okuqondile kumakhebuli angama-coaxial namathuluzi amaningi okuhlola (isb., izihlaziyo ze-spectrum, amamitha kagesi), okuvumela ukusebenza kwepulaki nokudlala nokwenza lula kakhulu ukuhlanganisa uhlelo kanye nomklamo wesekethe yangaphandle.

Izinhlelo zokusebenza ezijwayelekile:

1. Amasistimu e-radar: Amandla okukhipha isidlulisi esiqaphayo kanye nembobo ye-antenna ibonise amandla ngesikhathi sangempela, isebenza njengethuluzi elibalulekile "lomlindi" ukuvikela ama-transmitter abizayo kanye nokuqinisekisa ukusebenza okuzinzile kwesistimu ye-radar.
2. Iziteshi eziphansi zokuxhumana ngesathelayithi: Isetshenziselwa ukuqapha amandla e-uplink kanye nesampula yesignali ye-downlink, iqinisekisa ukuzinza nokuthembeka kwesixhumanisi sokuxhumana kuyilapho kuthuthukiswa ikhwalithi yokudlulisela.
3. Ukuhlola nokulinganisa zelabhorethri: Kungasetshenziswa njengesisekeli sangaphandle sezinhlelo zokuhlola ze-Vector Network Analyzer (VNA), evumela ukuhlolwa kwepharamitha ye-S, ukuhlolwa kokusebenza kwe-antenna, kanye nokulungiswa kwamaphutha kokumadanisa kwesistimu ngaphansi kwezimo zamandla aphezulu.
4. Izinyathelo zokulwa nomsakazo we-Microwave kanye ne-elekthronikhi (ECM): Kuqashwe ezinhlelweni zempi ye-elekthronikhi ezidinga ukulawulwa kwamandla okunembayo nokuhlaziya isignali yokuqapha isignali yesikhathi sangempela kanye nokulinganisa uhlelo.

I-Qualwave Inc. ihlinzeka ngochungechunge lwamabhangqa anamandla e-broadband anemvamisa efinyelela ku-220GHz. Phakathi kwazo, i-broadband high-power dual directional crossguide coupler isebenza ku-2.6GHz kuya ku-50.1GHz futhi isetshenziswa kakhulu kuma-amplifiers, ama-transmitters, ukuhlolwa kwaselabhorethri, izinhlelo ze-radar, nezinye izinhlelo zokusebenza ezihlukahlukene. Lesi sihloko sethula i-9~9.5GHz dual directional crossguide coupler.
