Isahluli samandla e-Wilkinson sisahluli esisebenzayo esisebenzisa iinguqu ezimbini, ezinxuseneyo, ezingadityaniswanga zekota-wavelength umgca wothumelo lwentambo. Ukusetyenziswa kweentambo zothumelo kwenza ukuba ukwahluli kweWilkinson kube lula ukuphumeza usebenzisa iintambo zothumelo lwesekethe ezisemgangathweni eziprintiweyo. Ubude beentambo zothumelo ngokuqhelekileyo bunciphisa uluhlu lwamaza osasazo lwe-Wilkinson divider ukuya kumaza angaphezulu kwama-500 MHz. I-resistor phakathi kwezibuko zemveliso ibavumela ukuba babe ne-impedances ehambelanayo ngelixa bebonelela ngokuzimeleyo. Ngenxa yokuba izibuko eziphumayo ziqulethe imiqondiso ye-amplitude efanayo kunye nesigaba, akukho mbane kwi-resistor, ngoko ke akukho mpompozo yangoku kwaye isichasi asichithi nawaphina amandla.
Abahluli bamandla
Isahluli samandla sinomqondiso omnye wegalelo kunye neempawu ezimbini okanye ngaphezulu zemveliso. Imiqondiso yemveliso inomgangatho wamandla oyi-1/N inqanaba lamandla egalelo apho i-N ilinani leziphumo kwisahluli. Imiqondiso kwiziphumo, kwezona ndlela zixhaphakileyo zesahluli samandla, zikwisigaba. Kukho izahluli zamandla ezikhethekileyo ezibonelela ngokutshintsha kwesigaba esilawulwayo phakathi kweziphumo. Izicelo zeRF eziqhelekileyo zezahluli zamandla, njengoko kukhankanyiwe ngaphambili, ziqondise umthombo oqhelekileyo weRF kwizixhobo ezininzi (Umfanekiso 1).
Umzobo womthombo weRF ojoliswe kwizixhobo ezininzi
Umzobo 1: Izahluli zamandla zisetyenziselwa ukwahlula isignali yeRF eqhelekileyo kwizixhobo ezininzi ezifana nenkqubo ye-antenna enezigaba okanye kwi-quadrature demodulator.
Umzekelo yi-eriyali yoluhlu olunezigaba apho umthombo weRF wahlulwe phakathi kwezinto ezimbini ze-eriyali. Ii-eriyali zolu hlobo ngokwesiqhelo zinezinto ezimbini ukuya kwezisibhozo okanye ngaphezulu, nganye kuzo iqhutywa ukusuka kwizibuko lokukhupha isahluli samandla. Iziguquli zesigaba ngokubanzi zingaphandle kwisahluli ukuvumela ulawulo lwe-elektroniki lokulawula i-eriyali yepateni.
Isahluli samandla sinokuqhutywa "ngasemva" ukwenzela ukuba amagalelo amaninzi adityaniswe kwimveliso enye eyenza ibe ngumdibanisi wamandla. Kwimowudi yokudibanisa ezi zixhobo ziyakwazi ukwenza ukongezwa kwe-vector okanye ukukhupha izibonakaliso ngokusekelwe kwi-amplitude kunye nemilinganiselo yesigaba.
Ukwahlula AmandlaIimbonakalo
• Izahluli zamandla zingasetyenziswa njengezihlanganisi okanye izahluli
• I-Wilkinson kunye nezahluli zamandla zokwahlula okuPhezulu zibonelela ngokwahlulwa okuphezulu, ukuvala umqondiso wokuthetha-thethana phakathi kwamazibuko aphumayo
• Ukufakwa okuphantsi kunye nelahleko yembuyekezo
• I-Wilkinson kunye nezahluli zamandla ezichasayo zibonelela ngokugqwesileyo (<0.5dB) i-amplitude kunye (<3°) ibhalansi yesigaba
• Izisombululo ze-octave ezininzi ukusuka kwi-DC ukuya kwi-50 GHz
Funda ngakumbi malunga nezahluli zamandla
Njengoko igama lisitsho, iRF/microwave isahluli samandla siya kwahlula isignali yegalelo ibe ziimpawu ezimbini ezilinganayo nezifanayo (okt kwisigaba) iimpawu. Isenokusetyenziswa njengomhlanganisi wamandla, apho izibuko eliqhelekileyo liyimveliso kunye namazibuko amabini alinganayo amandla asetyenziswa njengamagalelo. Iimpawu ezibalulekileyo xa zisetyenziswa njengesahluli samandla ziquka ilahleko yokufaka, ilahleko yokubuyisela, kunye ne-amplitude kunye ne-balance balance phakathi kweengalo. Ukudibanisa amandla emiqondiso engahambelaniyo, njengaxa usenza iimvavanyo ezichanekileyo ze-intermodulation distortion (IMD) njenge-IP2 kunye ne-IP3, olona phawu lubalulekileyo kukwahlulwa phakathi kwamazibuko okufakwayo.
Zintathu iindidi eziphambili zezahluli zamandla eRF kunye nezihlanganisi zamandla eRF: 0º, 90º hybrid, kunye ne-180º hybrid. Izahluli ze-RF ze-Zero-degree zahlula isignali yegalelo zibe ziimpawu zemveliso ezimbini okanye ngaphezulu ezilingana ngokwethiyori kuzo zombini i-amplitude kunye nesigaba. Izidibanisi zeRF ze-Zero-degree zidibanisa iisignali ezininzi zokungenisa ukunika imveliso enye. Xa ukhetha i-0 º izahluli, ulwahlulo lwezahluli zamandla luphawu olubalulekileyo ekufuneka luqwalaselwe. Le parameter linani leziphumo zesixhobo, okanye inani leendlela isignali yegalelo eyahlulwe ngayo kwisiphumo. Ukhetho lubandakanya i-2, 3, 4, 5, 6, 7, 8, 9, 12, 16, 32, 48, kunye nezixhobo zendlela engama-64.
Izahluli zamandla eRF / izahlulingamacandelo e-RF / microwave asetyenziselwa ukwahlula (okanye ukwahlula) iimpawu ze-microwave. I-Sichuan Keenlion Microwave Technology CO., Ltd abahluli bamandla babandakanya i-2-indlela, i-3-indlela, i-4-indlela, i-6-indlela, i-8-way kunye ne-48-way imodeli ye-50 Ohm kunye ne-75 ye-Ohm iinkqubo, kunye ne-DC-passing kunye ne-DC-blocking, kwi-coaxial, i-surface mount, kunye neefomati zokufa kwe-MMIC.
