Isihlukanisi samandla e-Wilkinson siyisihlukanisi esisebenzayo esisebenzisa ama-transformer amabili, ahambisanayo, angahlanganisiwe wekota ye-wavelength. Ukusetshenziswa kwemigqa yokudlulisela kwenza isihlukanisi se-Wilkinson sisebenzise kalula kusetshenziswa izintambo ezijwayelekile zokuhambisa isekethe ephrintiwe. Ubude bemigqa yokudlulisela ngokuvamile bukhawula ububanzi befrikhwensi yesihlukanisi se-Wilkinson kumafrikhwensi angaphezu kuka-500 MHz. I-resistor phakathi kwezimbobo zokukhiphayo ivumela ukuthi zibe nezinto ezifanayo ngenkathi zisahlinzeka ngokuhlukaniswa. Ngenxa yokuthi izimbobo zokukhiphayo ziqukethe amasiginali we-amplitude efanayo nesigaba, ayikho i-voltage kuyo yonke i-resistor, ngakho-ke akukho ukugeleza kwamanje futhi isixhasi asiwachithi noma yimaphi amandla.
Abahlukanisi bamandla
Isihlukanisi samandla sinesignali yokufaka eyodwa kanye namasignali okukhipha amabili noma ngaphezulu. Amasignali okukhiphayo anezinga lamandla elingu-1/N izinga lamandla okokufaka lapho u-N eyinombolo yokuphumayo kusihlukanisi. Amasignali kokuphumayo, ngendlela evamile kakhulu yesihlukanisi samandla, asesigabeni. Kunezihlukanisi zamandla ezikhethekile ezihlinzeka ngokushintsha kwesigaba esilawulwayo phakathi kokuphumayo. Izicelo ezijwayelekile ze-RF zezihlukanisi zamandla, njengoba kushiwo ngaphambili, ziqondisa umthombo we-RF ovamile kumadivaysi amaningi (Umfanekiso 1).
Umdwebo womthombo we-RF oqondiswe kumadivayisi amaningi
Umfanekiso 1: Izihlukanisi zamandla zisetshenziselwa ukuhlukanisa isignali ye-RF evamile kumadivayisi amaningi njengasohlelweni lwe-antenna yohlu olunezigaba noma kusiboniso esiyi-quadrature.
Isibonelo i-antenna yohlelo olunezigaba lapho umthombo we-RF uhlukaniswa phakathi kwezinto ezimbili ze-antenna. Ama-antenna alolu hlobo ngokwejwayelekile anezinto ezimbili kuya kweziyisishiyagalombili noma ngaphezulu, ngayinye eqhutshwa isuka embobeni yokukhipha isihlukanisi samandla. Iziguquli zesigaba ngokuvamile zingaphandle kwesihlukanisi ukuze zivumele isilawuli se-elekthronikhi ukuze siqondise uthi lwephethini yenkundla.
Isihlukanisi samandla singaqhutshwa “ngemuva” ukuze okokufaka okuningi kuhlanganiswe kube okukhiphayo okukodwa kusenze isihlanganisi samandla. Kumodi yokuhlanganisa lawa madivaysi ayakwazi ukwenza ukuhlanganisa ivekhtha noma ukususa amasignali ngokusekelwe ku-amplitude yawo kanye namanani esigaba.
• Izihlukanisi zamandla zingasetshenziswa njengezihlanganisi noma izihlukanisi
• I-Wilkinson kanye Nezihlukanisi zamandla ezihlukanisayo Eziphezulu zinikeza ukuhlukaniswa okuphezulu, okuvimba isignali yokuxoxisana phakathi kwezimbobo zokuphumayo
• Ukufakwa okuphansi nokulahlekelwa kokubuyisela
• I-Wilkinson kanye nezihlukanisi zamandla amelana zinikeza okuhle kakhulu (<0.5dB) amplitude kanye (<3°) nebhalansi yesigaba
• Izixazululo ze-Multi-octave kusuka ku-DC kuya ku-50 GHz

Njengoba igama lisho, isihlukanisi samandla e-RF/microwave sizohlukanisa isignali yokufaka ibe amasignali amabili alinganayo nafanayo (okungukuthi esigabeni). Ingase futhi isetshenziswe njengesihlanganisi samandla, lapho imbobo evamile iwukuphumayo nezimbobo zamandla ezimbili ezilinganayo zisetshenziswa njengokufakwayo. Ukucaciswa okubalulekile uma kusetshenziswa njengesihlukanisi samandla kufaka phakathi ukulahlekelwa kokufaka, ukulahlekelwa kwembuyiselo, ne-amplitude nebhalansi yesigaba phakathi kwezingalo. Ngokuhlanganiswa kwamandla amasiginali angaxhumene, njengalapho kwenziwa uhlolo olunembile lwe-intermodulation distortion (IMD) njenge-IP2 ne-IP3, ukucaciswa okubaluleke kakhulu ukuhlukaniswa phakathi kwezimbobo zokufaka.
Kunezinhlobo ezintathu eziyinhloko zezihlukanisi zamandla e-RF nezihlanganisi zamandla e-RF: 0º, 90 º hybrid, kanye ne-hybrid engu-180 º. Abahlukanisi be-RF be-Zero-degree bahlukanisa isignali yokufaka ibe amasiginali okukhiphayo amabili noma ngaphezulu alingana ngokombono kokubili i-amplitude nesigaba. Izihlanganisi ze-RF ze-Zero-degree zijoyina amasiginali okokufaka amaningi ukuze zinikeze okukhiphayo okukodwa. Uma ukhetha izihlukanisi ezingu-0 º, ukuhlukaniswa kwesihlukanisi samandla kuyisici esibalulekile okufanele sicatshangelwe. Le pharamitha inombolo yokuphuma kwedivayisi, noma inombolo yezindlela isignali yokokufaka ehlukaniswa ngayo ekuphumeni. Izinketho zifaka amadivayisi angu-2, 3, 4, 5, 6, 7, 8, 9, 12, 16, 32, 48, kanye ne-64-way.
Izihlukanisi / izihlukanisi zamandla e-RFziyizingxenye ze-RF/microwave ezisetshenziselwa ukuhlukanisa (noma ukuhlukanisa) amasiginali we-microwave. I-Sichuan Keenlion Microwave Technology CO.,Ltd izihlukanisi zamandla zihlanganisa 2-way, 3-way, 4-way, 6-way, 8-way nokufika ku-48-way amamodeli angu-50 Ohm namasistimu angu-75 Ohm, ane-DC-passing kanye ne-DC-blocking, nge-coaxial, i-surface mount, nefomethi yokufa ye-MMIC. Izihlukanisi zethu ze-coaxial zitholakala ngezixhumi ze-SMA, N-Type, F-Type, BNC, 2.92mm nezingu-2.4mm. Khetha kumamodeli angaphezu kwe-100 esitokweni anobubanzi befrikhwensi afika ku-50
I-GHz, ukuphatha amandla afika ku-200W, ukulahlekelwa kokufaka okuphansi, ukuhlukaniswa okuphezulu, nokungalingani kwe-amplitude okuhle kakhulu nokungalingani kwesigaba.
Singakwazi futhi ukwenza ngokwezifiso Isihlungi se-Band Pass ngokwezidingo zakho. Ungafaka ikhasi lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
