Isihlukanisi Samandla seWilkinson
Isihlukanisi samandla seWilkinson siyisihlukanisi esisebenzayo esisebenzisa ama-transformer amabili omugqa wokudlulisela we-quarter-wavelength amabili, ahambisanayo, angahlanganisiwe. Ukusetshenziswa kwemigqa yokudlulisela kwenza isihlukanisi seWilkinson kube lula ukuyisebenzisa kusetshenziswa imigqa yokudlulisela yesekethe ephrintiwe ejwayelekile. Ubude bemigqa yokudlulisela ngokuvamile bukhawulela ububanzi bemvamisa yesihlukanisi seWilkinson kumaza angaphezu kuka-500 MHz. I-resistor phakathi kwama-port okukhipha iwavumela ukuthi abe nama-impedances afanayo ngenkathi esanikeza ukuhlukaniswa. Ngenxa yokuthi ama-port okukhipha aqukethe izimpawu ze-amplitude kanye nesigaba esifanayo, akukho voltage kuyo yonke i-resistor, ngakho-ke akukho ukugeleza kwamanje futhi i-resistor ayichithi amandla.
Izihlukanisi zamandla
Isihlukanisi samandla sinesignali yokufaka eyodwa kanye nezibonakaliso ezimbili noma ngaphezulu zokukhipha. Izibonakaliso zokukhipha zinezinga lamandla elingu-1/N izinga lamandla okufaka lapho u-N kuyinani lemiphumela kusihlukanisi. Izibonakaliso eziphumayo, ngendlela evame kakhulu yesihlukanisi samandla, zisesigabeni. Kunezihlukanisi zamandla ezikhethekile ezihlinzeka ngokushintsha kwesigaba esilawulwayo phakathi kokukhiphayo. Izinhlelo zokusebenza ze-RF ezivamile zezihlukanisi zamandla, njengoba kushiwo ngaphambili, ziqondisa umthombo we-RF ojwayelekile kumadivayisi amaningi (Isithombe 1).
Umdwebo womthombo we-RF uqondiswe kumadivayisi amaningi
Umfanekiso 1: Izihlukanisi zamandla zisetshenziselwa ukuhlukanisa isignali ye-RF evamile kumadivayisi amaningi njengakuhlelo lwe-antenna olunezigaba noma ku-demodulator ye-quadrature.
Isibonelo i-antenna ye-phased array lapho umthombo we-RF uhlukaniswa khona phakathi kwezinto ezimbili ze-antenna. Ama-antenna alolu hlobo ngokuvamile anezinto ezimbili kuya kweziyisishiyagalombili noma ngaphezulu, ngasinye sazo siqhutshwa kusuka echwebeni lokukhipha elihlukanisa amandla. Ama-phase shifter ngokuvamile angaphandle kwesihlukanisi ukuze avumele ukulawula kwe-elekthronikhi ukuqondisa i-antenna yephethini yensimu.
Isihlukanisi samandla singaqhutshwa “sibheke emuva” ukuze okokufaka okuningi kuhlanganiswe kube umphumela owodwa okwenza kube yi-power combiner. Kumodi ye-combiner lawa madivayisi ayakwazi ukwenza ukwengeza noma ukususa amasignali nge-vector ngokusekelwe ku-amplitude yawo kanye namanani esigaba.
• Izihlukanisi zamandla zingasetshenziswa njengezihlanganisi noma izihlukanisi
• Izihlukanisi zamandla ze-Wilkinson kanye ne-High solitation zinikeza ukuhlukaniswa okuphezulu, ukuvimba izingxoxo phakathi kwama-port okukhiphayo
• Ukufakwa okuphansi kanye nokulahlekelwa kokubuya
• I-Wilkinson kanye nezihlukanisi zamandla okumelana zinikeza i-amplitude enhle kakhulu (<0.5dB) kanye ne-phase balance (<3°)
• Izixazululo ze-multi-octave kusukela ku-DC kuya ku-50 GHz
Funda Okwengeziwe Ngabahlukanisi Bamandla
Njengoba igama lisho, isihlukanisi samandla se-RF/microwave sizohlukanisa isignali yokufaka ibe yizibonakaliso ezimbili ezifanayo nezilinganayo (okungukuthi esigabeni). Singasetshenziswa futhi njengesihlanganisi samandla, lapho imbobo evamile ingumphumela kanti amambobo amabili alinganayo amandla asetshenziswa njengokufakwayo. Imininingwane ebalulekile uma isetshenziswa njengesihlukanisi samandla ifaka phakathi ukulahlekelwa kokufakwa, ukulahlekelwa kokubuya, kanye ne-amplitude kanye nebhalansi yesigaba phakathi kwezingalo. Ngokuhlanganisa amandla kwezibonakaliso ezingahlobene, njengalapho kwenziwa izivivinyo ezinembile ze-intermodulation distortion (IMD) njenge-IP2 kanye ne-IP3, incazelo ebaluleke kakhulu ukuhlukaniswa phakathi kwamambobo okufaka.
Kunezinhlobo ezintathu eziyinhloko zezihlukanisi zamandla e-RF kanye nezihlanganisi zamandla e-RF: i-0º, i-90 º hybrid, kanye ne-180 º hybrid. Izihlukanisi ze-RF ze-zero-degree zihlukanisa isignali yokufaka ibe yizibonakaliso ezimbili noma ngaphezulu zokukhipha ezilingana ngokomqondo kokubili ngobukhulu kanye nesigaba. Izihlanganisi ze-RF ze-zero-degree zihlanganisa izimpawu zokufaka eziningi ukuze zinikeze umphumela owodwa. Uma ukhetha izihlukanisi ze-0 º, ukuhlukaniswa kwehlukanisi yamandla kuyisici esibalulekile okufanele sicatshangelwe. Le pharamitha inani lemiphumela yedivayisi, noma inani lezindlela isignali yokufaka ehlukaniswe ngazo ekukhishweni. Izinketho zifaka phakathi amadivayisi angu-2, 3, 4, 5, 6, 7, 8, 9, 12, 16, 32, 48, kanye namadivayisi angu-64.
Izihlukanisi/izihlukanisi zamandla e-RFyizingxenye ze-RF / microwave ezingasebenzi ezisetshenziselwa ukuhlukanisa (noma ukuhlukanisa) izimpawu ze-microwave. Izihlukanisi zamandla ze-Sichuan Keenlion Microwave Technology CO.,Ltd zifaka amamodeli anezindlela ezimbili, izindlela ezintathu, izindlela ezine, izindlela eziyisithupha, izindlela eziyisishiyagalombili kanye nezindlela ezifika kwezingu-48 zezinhlelo ze-50 Ohm kanye ne-75 Ohm, ezine-DC-passing kanye ne-DC-blocking, kumafomethi e-coaxial, surface mount, kanye ne-MMIC die. Izihlukanisi zethu ze-coaxial ziyatholakala ngezixhumi ze-SMA, N-Type, F-Type, BNC, 2.92mm kanye ne-2.4mm. Khetha kusuka kumamodeli angaphezu kwe-100 esitokweni anebanga lemvamisa elifika ku-50
I-GHz, ukuphatha amandla afinyelela ku-200W, ukulahlekelwa okuphansi kokufakwa, ukuhlukaniswa okuphezulu, kanye nokungalingani okuhle kakhulu kwe-amplitude kanye nokungalingani kwesigaba.
Singakwazi futhi ukwenza ngokwezifiso i-Band Pass Filter ngokwezidingo zakho. Ungangena ekhasini lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
