Isixhumi Esihlanganisiwe Esihlanganisiwe Esingamadigri angu-90, Imvamisa engu-4 ~ 12GHz, Amandla Aphakathi angu-50W, I-SMA Yesifazane

I-coupler ye-hybrid engu-90 degrees iyidivayisi ye-microwave engasebenzi enezimbobo ezine. Uma isignali ifakwa kusuka kwenye yezimbobo, isabalalisa ngokulinganayo amandla esignali kuma-port amabili okukhipha (ingxenye ngayinye, okungukuthi -3dB), futhi kukhona umehluko wesigaba esingu-90 degrees phakathi kwalezi zimpawu ezimbili zokukhipha. Elinye imbobo liyisici esihlukile, okungcono kakhulu ngaphandle kokukhipha amandla. Okulandelayo kwethula kafushane izici zayo kanye nezinhlelo zokusebenza:

Izici Eziyinhloko:

1. Ukumbozwa kwemvamisa ye-Ultra-wideband
Isekela ukusebenza kwe-ultra-wideband kusukela ku-4 kuya ku-12 GHz, imboza kahle i-C-band, i-X-band, kanye nengxenye yezinhlelo zokusebenza ze-Ku-band. Ingxenye eyodwa ingathatha indawo yamadivayisi amaningi e-narrowband, yenza kube lula ukuklama uhlelo futhi inciphise isitokwe kanye nezindleko.
2. Amandla aphezulu okuphatha
Idizayini enhle kakhulu yokushisa neyokwakheka ivumela ukuphathwa okuzinzile kwamandla okufaka afinyelela ku-50W, okuhlangabezana nezidingo ezidingekayo zezixhumanisi eziningi zokudlulisa amandla aphezulu. Inikeza ukuthembeka okuphezulu kanye nokuphila isikhathi eside kwenkonzo.
3. Ukuhlanganiswa kwe-quadrature ye-3dB okunembile
Iqukethe umehluko onembile wesigaba sama-degree angu-90 (i-quadrature) kanye nokuhlanganiswa kwe-3dB. Ibonisa ibhalansi ye-amplitude enhle kakhulu kanye nokulahlekelwa okuphansi kokufakwa, ihlukanisa ngempumelelo isignali yokufaka ibe amasignali amabili okukhiphayo ane-amplitude efanayo kanye nesigaba se-orthogonal.
4. Ukuhlukaniswa okuphezulu kanye nokuqhathaniswa okuhle kakhulu kwembobo
Imbobo ehlukanisiwe ifaka umthwalo wangaphakathi ohambisanayo, ihlinzeka ngokuhlukaniswa okuphezulu futhi inciphisa ngempumelelo ukuxhumana kwesignali phakathi kwama-port, iqinisekisa ukuzinza kwesistimu. Zonke izimbobo zinesilinganiso esihle kakhulu samagagasi okuma kwe-voltage (VSWR) kanye nokufanisa imbobo, okunciphisa ukubonakaliswa kwesignali ngezinga elikhulu.
5. Isixhumi esibonakalayo sabesifazane se-SMA esijwayelekile
Ifakwe ama-interface e-SMA female (SMA-F), ahambisana nezindinganiso zemboni. Anikeza ukuxhumana okulula nokuthembekile, okuvumela ukuhlanganiswa okuqondile nezintambo eziningi ze-SMA zabesilisa kanye nama-adaptha emakethe.
6. Ikhwalithi eqinile yezinga lezempi
Yakhiwe ngembobo yensimbi evikelwe ngokuphelele, inesakhiwo esiqinile, ukumelana okuhle kakhulu nokudlidliza kanye nomthelela, kanye nezici zokuvikela kagesi eziphezulu. Inikeza ukusebenza okuzinzile ngisho nasezimweni zemvelo ezinzima.

Izicelo Ezijwayelekile:

1. Izinhlelo ze-radar ezihleliwe ngezigaba: Zisebenza njengeyunithi eyinhloko kuma-Beamforming Networks (BFN), zinikeza izimpawu zokuvuselela ezinobudlelwano besigaba esithile nezinto eziningi ze-antenna zokuskena ngomsebe we-elekthronikhi.
2. Izinhlelo ze-amplifier ezinamandla aphezulu: Zisetshenziswa ekwakhiweni kwe-amplifier elinganiselayo yokusatshalaliswa kwesignali kanye nokuhlanganiswa, zithuthukisa amandla okukhipha uhlelo kanye nokuthembeka ngenkathi zithuthukisa ukufana kokufaka/okukhiphayo.
3. Ukuguqulwa kwesignali kanye nokususwa kwesignali: Isebenza njengomkhiqizi wesignali we-quadrature wabashintshi be-I/Q kanye nabashintshi be-demodulators, okwenza kube yingxenye ebalulekile ezinhlelweni zokuxhumana zanamuhla kanye nokuzulazula kwe-radar.
4. Izinhlelo zokuhlola nokulinganisa: Zisebenza njengesihlukanisi samandla esinembile, isihlanganisi, noma idivayisi yokubhekisela yesigaba kumapulatifomu okuhlola ama-microwave okusabalalisa isignali, ukuhlanganiswa, kanye nokulinganisa isigaba.
5. Izinhlelo zokulinganisa ngogesi (ECM): Ezisetshenziselwa ukukhiqiza izimpawu eziguquguqukayo eziyinkimbinkimbi nokwenza ukucubungula izimpawu, ukuhlangabezana nezidingo ze-broadband kanye namandla aphezulu ezinhlelo zempi kagesi.

I-Qualwave Inc. inikeza ama-broadband kanye nama-couplers e-hybrid angu-90 degrees anamandla aphezulu kusukela ku-1.6MHz kuya ku-50GHz, asetshenziswa kabanzi emikhakheni eminingi. Lesi sihloko sethula i-coupler ye-hybrid engu-90 degrees enamandla ajwayelekile angu-50W kumaza asukela ku-4 kuya ku-12GHz.
