Ukunqongophala kwezahluli zamandla kwizicelo zokudibanisa amandla aphezulu kunokubangelwa zezi zinto zilandelayo ziphambili:
1. Imida yoLawulo lwaMandla ye-Isolation Resistor (R)
- Imo Yokwahlukanisa Amandla:
- Xa isetyenziswa njengesihluli samandla, isignali yokufaka kwiINyahlulwe yaba ziimpawu ezimbini ze-co-frequency, i-co-phase kwiindawoAkwayeB.
- Isithinteli sokuzihlukanisaRAyifumani mahluko kwi-voltage, nto leyo ebangela ukuba kubekho ukuhamba kwamandla ombane okungekho zero kwaye kungabikho ukuchithwa kwamandla. Umthamo wamandla umiselwa kuphela bubuchule bokuphatha amandla bomgca we-microstrip.
- Imo yoMdibanisi:
- Xa isetyenziswa njengesixhobo sokudibanisa, iimpawu ezimbini ezizimeleyo (ukusuka kwiOUT1kwayeOUT2) kunye neefrikhwensi okanye izigaba ezahlukeneyo ziyasetyenziswa.
- Umahluko we-voltage uvela phakathiAkwayeBokubangela ukuhamba komsingaRAmandla anyamalala ngoRzilingana½ (OUT1 + OUT2)Umzekelo, ukuba igalelo ngalinye liyi-10W,Rkufuneka imelane nobushushu obungaphezulu kwe-10W.
- Nangona kunjalo, i-isolation resistor kwi-standard power dividers idla ngokuba yinxalenye yamandla aphantsi kwaye ayinakusasazeka ngokwaneleyo kobushushu, nto leyo eyenza ukuba ingakwazi ukufudumala kakuhle phantsi kweemeko zamandla aphezulu.
2. Imiqobo yoYilo lweZakhiwo
- Imida yoMgca weMicrostrip:
- Izihluli zamandla zihlala zisetyenziswa kusetyenziswa imigca ye-microstrip, enomthamo omncinci wokuphatha amandla kunye nolawulo olungonelanga lobushushu (umz., ubungakanani obuncinci bomzimba, indawo yokusasaza ubushushu obuphantsi).
- I-resistorRAyilungiselelwanga ukusasazwa kwamandla aphezulu, nto leyo ethintela ngakumbi ukuthembeka kwizicelo zokudibanisa.
- Uvakalelo lweSigaba/Ubuninzi:
- Nakuphi na ukungangqinelani kwesigaba okanye kwamaza phakathi kwemiqondiso emibini yokufaka (eqhelekileyo kwiimeko zokwenyani) kwandisa ukuchithwa kwamandla kwiR, okwandisa uxinzelelo lobushushu.
3. Imida kwiMiba eQhelekileyo yokuQokelela/yokuQokelela iSigaba
- Ityala lethiyori:
- Ukuba ii-input ezimbini zihambelana ngokugqibeleleyo kunye ne-co-phase (umz., ii-amplifier ezihambelanayo eziqhutywa sisignali efanayo), Rayichithi mandla, kwaye amandla ewonke adityaniswe kwiIN.
- Umzekelo, ii-input ezimbini ze-50W zinokudityaniswa ngokwethiyori zibe yi-100W kwi-INukuba imigca ye-microstrip inokuphatha amandla apheleleyo.
- Imingeni Esebenzayo:
- Ulungelelwaniso lwesigaba olugqibeleleyo phantse alunakwenzeka ukugcina kwiinkqubo zokwenyani.
- Abahluli bamandla abanalo ukuqina kokudibanisa amandla aphezulu, njengoko nokungafani okuncinci kunokubangelaRukufunxa ukunyuka kwamandla okungalindelekanga, okukhokelela ekusileleni.
4. Ubungakanani beZisombululo eziKhethekileyo (umz., ii-3dB Hybrid Couplers)
- IziXhobo zeHybrid ze-3dB:
- Sebenzisa izakhiwo zemiqolo ezineesiphelo zangaphandle zomthwalo onamandla aphezulu, nto leyo evumela ukusasazwa kobushushu ngokufanelekileyo kunye nomthamo ophezulu wokuphatha amandla (umz., 100W+).
- Nika ukwahlulwa okuqhelekileyo phakathi kweeports kwaye unyamezele ukungahambelani kwesigaba/frequency. Amandla angahambelaniyo adluliselwa ngokukhuselekileyo kumthwalo wangaphandle endaweni yokonakalisa izinto zangaphakathi.
- Ukuguquguquka koyilo:
- Uyilo olusekelwe kwi-cavity luvumela ulawulo lobushushu olunokwandiswa kunye nokusebenza okuqinileyo kwizicelo zamandla aphezulu, ngokungafaniyo nezahluli zamandla ezisekelwe kwi-microstrip.
Isiphelo
Izihluzi zamandla azifanelekanga ekudibaniseni amandla aphezulu ngenxa yokuba isithinteli sokwahlulwa kwamandla sincinci, uyilo olungafanelekanga lobushushu, kunye novakalelo lokungafani kwesigaba/imvamisa. Kwanakwiimeko ezifanelekileyo zesigaba esinye, imida yolwakhiwo kunye nokuthembeka kuyenza ingasebenzi. Kwizixhobo ezidibanisa isignali enamandla aphezulu, izixhobo ezizinikeleyo ezifana ne-Izihlanganisi ze-3dB ezixutyiweyoZiyathandwa kakhulu, zibonelela ngokusebenza kakuhle kobushushu, ukunyamezelana nokungalingani, kunye nokuhambelana noyilo lwamandla aphezulu olusekwe kwi-cavity.
