I-Attenuator Engahlelwa, 0.02~18GHz, Ibanga Lokunciphisa 0~63.75dB, Isinyathelo 0.25dB

Njengengxenye ebalulekile ezinhlelweni zokuhlola nokuxhumana nge-microwave, i-Programmable Attenuator ilungisa ngokunembile ubukhulu besiginali ye-microwave ngokulawula inethiwekhi yokumelana nokunemba kwangaphakathi ngemiyalo yedijithali. Inani layo eliyinhloko lisekushintsheni ama-attenuator endabuko asetshenziswa ngesandla, ahlinzeka ngokulawula isiginali okuzenzakalelayo okunesinqumo esiphezulu, okunembile kakhulu ngaphakathi kwebhendi yemvamisa ebanzi ukuze kuhlangatshezwane nezidingo zezinhlelo zesimanje ze-elekthronikhi zokusebenza kude kanye nokuphendula okusheshayo. Okulandelayo yisingeniso esinemininingwane esivela ezicini ezimbili: izici zayo eziyinhloko zomkhiqizo kanye nezindawo eziyinhloko zohlelo lokusebenza.

Izici:

1. Ukunemba okuphezulu kanye nesinyathelo esincane: Lo mkhiqizo unesinyathelo esincane esingu-0.25dB, okuvumela ukulungiswa kwe-amplitude yesignali encane kakhulu. Ububanzi bokunciphisa bufinyelela ku-63.75dB, buhlanganisa ububanzi obuhlukahlukene obushintshashintshayo kusukela kuzimpawu ezibuthakathaka kuya kwezinamandla. Ukunemba kwawo okuvamile kokunciphisa kungafinyelela ku-±2dB, okuqinisekisa ukunemba nokuphindeka ngaphansi kwezilungiselelo ezahlukahlukene.
2. Ukumbozwa kwemvamisa ye-Ultra-wideband: Imvamisa yokusebenza isukela ku-0.02GHz kuya ku-18GHz, imboza cishe wonke ama-band okuxhumana abalulekile kanye ne-radar. Lokhu kumbozwa kwemvamisa ebanzi kuyivumela ukuthi iphathe amasignali kuwo wonke ama-band ahlukene epulatifomu eyodwa, isuse isidingo sokushintsha amadivayisi amaningi.
3. Ukulahlekelwa okuphansi kokufakwa kanye nokuhambisana okuhle: Ukulahlekelwa kwayo okuphezulu kokufakwa kulawulwa ngaphakathi kwe-8dB, kunciphisa ukusetshenziswa kwamandla esignali yokuqala. Okwamanje, isilinganiso esiphezulu samagagasi okuma kwamandla kagesi emachwebeni ayo okufaka nawokukhiphayo singu-2.0, okuqinisekisa ukuhambisana okuhle kwe-impedance nezinhlelo ze-50Ω, kunciphisa ngempumelelo ukubonakaliswa kwesignali futhi kuqinisekisa ubuqotho bokudluliselwa kwesignali.
4. Ukulawula okuhlelekile okunokwethenjelwa kanye nomklamo wesakhiwo: Umkhiqizo usekela ukulawula okukude ngokusebenzisa izixhumi ezijwayelekile, okwenza kube lula ukuhlanganiswa ezinhlelweni zokuhlola ezenzakalelayo. Eminye imiklamo icabangela nokuzivumelanisa nezimo zemvelo, igcine ukusebenza okuzinzile ebangeni elikhulu lokushisa.

Izicelo:

1. Ukuhlolwa kohlelo lokuxhumana: Ku-R&D kanye nokukhiqizwa kweziteshi zesisekelo ze-5G, iziteshi zomhlaba zokuxhumana ngesathelayithi, kanye nezinhlelo ze-radar, lesi sivikelo sisetshenziswa kabanzi ukulingisa ukulahleka kokudluliselwa kwesignali emkhathini.
2. Izinhlelo zokuhlola ezizenzakalelayo: Njengengxenye eyinhloko yokulungisa isignali ezinhlelweni ze-ATE, ingalawula ngokunembile ukufakwa kwezinga lesignali kumathuluzi afana nabahlaziyi be-spectrum, abakhiqizi besignali, noma amamitha kagesi. Lokhu akugcini nje ngokuvimbela umonakalo emishinini yokuhlola ebizayo ngenxa yamandla esignali amaningi kodwa futhi kuqinisekisa ukuthi izilinganiso zithathwa nge-amplitude yesignali efanele, ngaleyo ndlela kuthuthukiswe ububanzi obuguqukayo kanye nokunemba kokulinganisa kohlelo lonke lokuhlola.
3. Ukuhlolwa kwemigqa yezingxenye kanye nokukhiqiza: Ekuhlolweni kokukhiqizwa kwezingxenye ze-RF kanye ne-microwave, le divayisi isetshenziselwa ukwenza ngokushesha nangokunembile ukuqinisekiswa kokusebenza kanye nokuhlolwa kokusebenza. Ngokushintsha ngokuzenzakalelayo amandla esignali yokufaka, ijika lokuphendula ledivayisi elivivinywa ngaphansi kwezimo zesignali ezahlukene lingadwetshwa kahle.
4. Ucwaningo kanye nokuhlolwa kwezemfundo: Emalabhorethri e-microwave amanyuvesi kanye nezikhungo zocwaningo, kuyingxenye eyisisekelo yokwakha amapulatifomu okuhlola okulingisa iziteshi kanye nocwaningo lokusabalala kwamagagasi, kusiza abacwaningi ukulingisa izindawo eziyinkimbinkimbi ze-electromagnetic nokuqinisekisa amamodeli nemiklamo yethiyori.

I-Qualwave Inc. inikeza ububanzi obukhulu, ububanzi obuguquguqukayoizinciphisi ezihlelekayongamaza afinyelela ku-40GHz. Isinyathelo singafinyelela ku-0.5dB, kanti ububanzi bokunciphisa amandla bungafinyelela ku-80dB noma ngaphezulu. Lesi sihloko sethula i-attenuator ehlelwe engu-0.02~18GHz enobubanzi bokunciphisa amandla obungu-0~63.75dB kanye nesinyathelo esingu-0.25dB.
