Isihluli samandla sikaWilkinson
I-Wilkinson power divider sisihluli esisebenzayo esisebenzisa ii-transformers ezimbini ze-quarter-wavelength transmission line transmission transformers, parallel, uncoupled. Ukusetyenziswa kwemigca yokudlulisa kwenza kube lula ukuyisebenzisa i-Wilkinson divider kusetyenziswa imigca yokudlulisa yesekethe eprintiweyo eqhelekileyo. Ubude bemigca yokudlulisa buhlala buthintela uluhlu lwefrikhwensi ye-Wilkinson divider ukuya kwiifrekhwensi ezingaphezulu kwe-500 MHz. I-resistor phakathi kwe-output ports ivumela ukuba zibe ne-matching impedances ngelixa zisabonelela nge-isolation. Ngenxa yokuba i-output ports ziqulathe imiqondiso ye-amplitude kunye ne-phase efanayo, akukho voltage kwi-resistor, ngoko akukho current flows kwaye i-resistor ayichithi amandla.
Abahluli bamandla
Isixhobo sokwahlula amandla sinesignali enye yokufaka kunye nemiqondiso emibini okanye ngaphezulu yokuphuma. Imiqondiso yokuphuma inenqanaba lamandla eliyi-1/N inqanaba lamandla okufaka apho u-N linani leemveliso kwisixhobo sokwahlula amandla. Imiqondiso kwizixhobo zokuphuma, ngendlela eqhelekileyo yesixhobo sokwahlula amandla, ikwisigaba. Kukho izixhobo zokwahlula amandla ezikhethekileyo ezibonelela ngotshintsho lwesigaba esilawulwayo phakathi kwezixhobo zokuphuma. Izicelo zeRF eziqhelekileyo zezixhobo zokwahlula amandla, njengoko bekutshiwo ngaphambili, ziqondisa umthombo weRF oqhelekileyo kwizixhobo ezininzi (Umfanekiso 1).
Umzobo womthombo we-RF ujoliswe kwizixhobo ezininzi
Umfanekiso 1: Izihluli zamandla zisetyenziselwa ukwahlula isignali yeRF eqhelekileyo kwizixhobo ezininzi ezifana nenkqubo ye-antenna ye-phased array okanye kwi-quadrature demodulator.
Umzekelo yi-antenna ye-phased array apho umthombo we-RF wahlulwe phakathi kwezinto ezimbini ze-antenna. Ii-antenna zolu hlobo ngokwesiqhelo zinezinto ezimbini ukuya kwezisibhozo okanye ngaphezulu, nganye kuzo iqhutywa kwi-port ye-output divider power divider. Ii-Phase shifters zihlala zingaphandle kwe-divider ukuvumela ulawulo lwe-elektroniki ukuba lulawule i-antenna yepateni yentsimi.
Isihluzi samandla sinokuqhutywa "ngasemva" ukuze amagalelo amaninzi adityaniswe abe yimveliso enye nto leyo eyenza ukuba ibe yi-power combiner. Kwimo ye-combiner ezi zixhobo ziyakwazi ukwenza ukongeza okanye ukuthabatha imiqondiso yevektha ngokusekelwe kwi-amplitude kunye ne-phase values zazo.
Isihluli samandlaIimbonakalo
• Izihluzi zamandla zingasetyenziswa njengezihlanganisi okanye izihluzi
• Izihluli zamandla zeWilkinson kunye neHigh solidation zibonelela nge-isolidation ephezulu, zivimba i-cross talk phakathi kwee-output ports
• Ukufakwa okuphantsi kunye nokulahleka kokubuya
• I-Wilkinson kunye nezahluli zamandla ezikhuselayo zibonelela nge-amplitude egqwesileyo (<0.5dB) kunye ne-phase balance (<3°)
• Izisombululo ze-multi-octave ukusuka kwi-DC ukuya kwi-50 GHz
Funda Okungakumbi Ngabo Bahluli Bamandla
Njengoko igama lisitsho, isahluli samandla se-RF/microwave siya kwahlula isignali yokufaka ibe ziimpawu ezimbini ezifanayo nezilinganayo (oko kukuthi kwisigaba). Ingasetyenziswa njengesixhobo sokudibanisa amandla, apho izibuko eliqhelekileyo liyimveliso kwaye iizibuko zamandla ezimbini ezilinganayo zisetyenziswa njengezixhobo zokungenisa. Iinkcukacha ezibalulekileyo xa zisetyenziswa njengesixhobo sokwahlula amandla ziquka ilahleko yokufakwa, ilahleko yokubuya, kunye ne-amplitude kunye ne-phase balance phakathi kweengalo. Ukudibanisa amandla eesignali ezingadibaniyo, njengaxa kwenziwa uvavanyo oluchanekileyo lwe-intermodulation distortion (IMD) njenge-IP2 kunye ne-IP3, eyona nkcazelo ibalulekileyo kukwahlulwa phakathi kweezibuko zokungenisa.
Kukho iintlobo ezintathu eziphambili zezahluli zamandla e-RF kunye nee-RF power combiners: i-0º, i-90º hybrid, kunye ne-180º hybrid. Izahluli ze-RF ze-Zero-degree zahlula isignali yokufaka ibe ziimpawu ezimbini okanye ngaphezulu zokukhupha ezilinganayo ngokwethiyori kwi-amplitude nakwi-phase. Izahluli ze-RF ze-Zero-degree zidibanisa izibonakaliso ezininzi zokufaka ukuze zinike imveliso enye. Xa ukhetha izahluli ze-0º, ulwahlulo lwamandla luphawu olubalulekileyo ekufuneka luqwalaselwe. Le parameter linani leemveliso zesixhobo, okanye inani leendlela isignali yokufaka eyahlulwe ngazo kwimveliso. Ukhetho luquka izixhobo ezi-2, 3, 4, 5, 6, 7, 8, 9, 12, 16, 32, 48, kunye ne-64-way.
Izihluzi/izihluzi zamandla ze-RFziinxalenye ze-RF / microwave ezingasebenziyo ezisetyenziselwa ukwahlulahlula (okanye ukwahlula) imiqondiso ye-microwave. I-Sichuan Keenlion Microwave Technology CO.,Ltd power splitters ziquka iimodeli zeendlela ezimbini, iindlela ezintathu, iindlela ezine, iindlela ezi-6, iindlela ezi-8 kunye neendlela ezifikelela kuma-48 zeenkqubo ze-50 Ohm kunye ne-75 Ohm, ezine-DC-passing kunye ne-DC-blocking, kwiifomathi ze-coaxial, surface mount, kunye ne-MMIC die.
