Iimpawu ze-AGC kunye ne-MGC ze-Mobile Signal Boosters
I-AGC (Automatic Gain Control) kunye ne-MGC (Manual Gain Control) ziimpawu ezimbini eziqhelekileyo zokulawula i-gain ezifumaneka kwi-mobile signal boosters.
1.AGC (Ulawulo Lokufumana Okuzenzekelayo):Olu phawu lulungisa ngokuzenzekelayo i-gain ye-booster ukuze igcine isignali ye-output ngaphakathi koluhlu oluthile. Inkqubo ye-AGC idla ngokuba ne-variable gain amplifier kunye ne-feedback loop. I-feedback loop ikhupha ulwazi lwe-amplitude kwi-output signal kwaye ilungisa i-amplifier's gain ngokufanelekileyo. Xa amandla esignali ye-input enyuka, i-AGC inciphisa i-gain; ngokuchaseneyo, xa isignali ye-input iyancipha, i-AGC inyusa i-gain. Izinto eziphambili ezibandakanyekayo ziquka:
-Isikhangeli se-AGC:Ijonga ubukhulu besignali yesiphumo se-amplifier.
-Isihluzi sokuthambisa esilula:Isusa izinto ezisebenza rhoqo kunye nengxolo evela kwisignali efunyenweyo ukuze ivelise i-voltage yokulawula.
-Isekethe yeVolthi yoLawulo:Ivelisa i-voltage yokulawula esekelwe kwisignali ehluziweyo ukuze ilungise inzuzo ye-amplifier.
-I-Gate Circuit kunye ne-DC Amplifier:Ezi zingabandakanywa ukuze kuphuculwe ngakumbi kwaye kuphuculwe ulawulo lokuzuza.
2.MGC (Ulawulo Lokufumana Imali Ngesandla):Ngokungafaniyo ne-AGC, i-MGC ivumela abasebenzisi ukuba balungise ngesandla i-amplifier's gain. Olu phawu lunokuba luncedo kwiimeko ezithile apho ulawulo lwe-gain oluzenzekelayo lungahlangabezani neemfuno ezithile, nto leyo evumela abasebenzisi ukuba baphucule umgangatho wesignali kunye nokusebenza kwesixhobo ngokulungiswa ngesandla.
Ngokwenyani, i-AGC kunye ne-MGC zingasetyenziswa ngokuzimeleyo okanye zidityaniswe ukubonelela ngesisombululo sokukhulisa isignali esiguquguqukayo ngakumbi. Umzekelo, ezinye izixhobo zokukhulisa isignali eziphathwayo eziphambili zibandakanya zombini imisebenzi ye-AGC kunye ne-MGC, evumela abasebenzisi ukuba batshintshe phakathi kweendlela ezizenzekelayo kunye nezandla ngokusekelwe kwiindawo ezahlukeneyo zesignali kunye neemfuno zomsebenzisi.
Izinto eziqwalaselwayo kuYilo lwe-AGC kunye ne-MGC
Xa kuyilwa ii-algorithms ze-AGC, izinto ezifana neempawu zesignali kunye nezinto ze-RF front-end zibalulekile. Ezi ziquka useto lokuqala lwe-AGC gain, ukufunyanwa kwamandla esignali, ulawulo lwe-AGC gain, ukulungiswa kwexesha rhoqo, ulawulo lomgangatho wengxolo, ulawulo lwe-gain saturation, kunye nokulungiswa kobubanzi obuguqukayo. Zizonke, ezi zinto zimisela ukusebenza kunye nokusebenza kakuhle kwenkqubo ye-AGC.
Kwizixhobo zokunyusa isignali yeselula, imisebenzi ye-AGC kunye ne-MGC idla ngokudityaniswa nezinye iindlela zokulawula ezikrelekrele, ezifana ne-ALC (Automatic Level Control), i-ISO self-oscillation elimination, i-uplink idle shutdown, kunye ne-automatic power shutoff, ukubonelela ngezisombululo zokukhulisa isignali ezisebenzayo nezithembekileyo. Ezi mpawu ziqinisekisa ukuba i-amplifier inokulungisa ngokuzenzekelayo imeko yayo yokusebenza ngokusekelwe kwiimeko zokwenyani zesignali, iphucule ukugubungela isignali, inciphise ukuphazamiseka kwizikhululo zesiseko, kwaye iphucule umgangatho wonxibelelwano ngokubanzi.
