Imashanyarazi ya Wilkinson ni igabanywa rikoresha ibintu bibiri, bigereranye, bidahujwe na kimwe cya kane cyumurongo woherejwe. Gukoresha imirongo yohereza bituma Wilkinson igabanya byoroshye gushyira mubikorwa ukoresheje imirongo isanzwe yumuzunguruko. Uburebure bw'imirongo yohereza muri rusange bugabanya umurongo wa diviziyo ya Wilkinson kugeza kuri 500 MHz. Kurwanya hagati yicyambu gisohoka kibemerera kugira inzitizi zihuye mugihe bagitanga wenyine. Kuberako ibyasohotse bisohoka birimo ibimenyetso bya amplitude hamwe nicyiciro kimwe, nta voltage ihari kururwanya, bityo ntamugezi ugenda kandi na rezistor ntisohora imbaraga.
Abatandukanya imbaraga
Imashanyarazi igabanya ibimenyetso byinjiza kimwe nibimenyetso bibiri cyangwa byinshi bisohoka. Ibisohoka bisohoka bifite imbaraga zingana ni 1 / N urwego rwinjiza urwego aho N numubare wibisubizo mubigabana. Ibimenyetso ku bisohoka, muburyo busanzwe bwo kugabana imbaraga, biri mubice. Hariho imbaraga zidasanzwe zitanga zitanga ibyiciro bigenzurwa hagati yibisohoka. Porogaramu rusange ya RF kubatandukanya ingufu, nkuko byavuzwe mbere, iyobora isoko rusange ya RF kubikoresho byinshi (Ishusho 1).
Igishushanyo cyinkomoko ya RF yerekanwe kubikoresho byinshi
Igishushanyo 1: Gutandukanya ingufu zikoreshwa mukugabanya ibimenyetso rusange bya RF kubikoresho byinshi nko muri sisitemu ya antenna ya etape cyangwa muri demodulator ya quadrature.
Urugero ni antenne yicyiciro cya array aho isoko ya RF igabanijwe hagati ya antenne ebyiri. Antenne yubwoko busanzwe ifite ibintu bibiri kugeza umunani cyangwa byinshi, buri kimwe kiva mumashanyarazi agabanya icyambu. Guhinduranya ibyiciro mubisanzwe hanze kubigabanya kugirango yemererwe kugenzura ibyuma bya elegitoronike kuyobora antenne yumurima.
Imbaraga zigabanya imbaraga zishobora gukoreshwa "inyuma" kugirango inyongeramusaruro nyinshi zishobora guhurizwa hamwe mugisohoka kimwe bigatuma imbaraga zihuza. Muburyo bwo guhuza ibyo bikoresho birashobora gukora vector yongeyeho cyangwa gukuramo ibimenyetso ukurikije amplitude hamwe nibiciro byicyiciro.
Gutandukanya ImbaragaIbiranga
• Gutandukanya ingufu birashobora gukoreshwa nka kombineri cyangwa ibice
• Wilkinson hamwe nogutandukanya imbaraga zitanga imbaraga zitanga kwigunga cyane, guhagarika ibimenyetso byambukiranya ibiganiro hagati yicyambu
• Kwinjiza bike no gutakaza igihombo
• Wilkinson hamwe nimbaraga zigabanya imbaraga zitanga amplitude nziza (<0.5dB) hamwe na (<3 °) impagarike yicyiciro
• Ibisubizo byinshi-octave kuva DC kugeza 50 GHz
Wige Byinshi Kubatandukanya Imbaraga
Nkuko izina ribivuga, RF / microwave power divider izagabanya ibimenyetso byinjira mubice bibiri bingana kandi bisa (ni ukuvuga mubice). Irashobora kandi gukoreshwa nkimbaraga zihuza imbaraga, aho icyambu gisanzwe aricyo gisohoka kandi ibyambu bibiri bingana byifashishwa nkibisubizo. Ibisobanuro byingenzi iyo bikoreshejwe nkigabanywa imbaraga harimo igihombo cyo gushiramo, igihombo cyo kugaruka, hamwe na amplitude hamwe nuburinganire hagati yintwaro. Ku mbaraga zihuza ibimenyetso bidafitanye isano, nko mugihe ukora ibizamini byo kugoreka intermodulation (IMD) nka IP2 na IP3, icyangombwa cyingenzi nukwitandukanya hagati yicyambu.
Hariho ubwoko butatu bwingenzi bwo gutandukanya ingufu za RF hamwe na RF power combiners: 0º, 90 º hybrid, na 180 º hybrid. Zero-degre ya RF igabanya ibimenyetso byinjiza mubice bibiri cyangwa byinshi bisohoka byerekana ko bingana muburyo bwa amplitude hamwe nicyiciro. Impamyabumenyi ya Zeru ya RF ihuza ibimenyetso byinshi byinjiza kugirango itange umusaruro umwe. Iyo uhisemo 0 º abatandukanya, kugabana imbaraga ni ikintu cyingenzi cyo gusuzuma. Iyi parameter numubare wibisubizo byigikoresho, cyangwa umubare winzira ibimenyetso byinjira bigabanijwe kubisohoka. Guhitamo birimo ibikoresho 2, 3, 4, 5, 6, 7, 8, 9, 12, 16, 32, 48, na 64-inzira.
RF itandukanya / ibiceni pasiporo ya RF / microwave ikoreshwa mugutandukanya (cyangwa kugabanya) ibimenyetso bya microwave. Sichuan Keenlion Microwave Technology CO., Ltd itandukanya amashanyarazi harimo inzira 2, inzira-3, inzira-4, inzira-6, inzira-8 na moderi zigera kuri 48 kuri sisitemu 50 Ohm na 75 Ohm, hamwe na DC-kunyura hamwe na DC-guhagarika, muburyo bwa coaxial, hejuru yubuso, na MMIC bipfa. Ibice byacu bya coaxial birahari hamwe na SMA, N-Ubwoko, F-Ubwoko, BNC, 2.92mm na 2.4mm. Hitamo muri moderi zirenga 100 mububiko hamwe ninshuro zigera kuri 50
GHz, gukoresha ingufu zigera kuri 200W, igihombo gike cyo kwinjiza, kwigunga cyane, hamwe no kutagira amplitude hamwe no kuringaniza icyiciro.
Turashobora kandi guhitamo Band Pass Filter dukurikije ibyo usabwa. Urashobora kwinjiza urupapuro rwihariye kugirango utange ibisobanuro ukeneye.
