Ngaphandle kwesihluzo kwisiphelo seRF RF, isiphumo sokwamkela siya kuncitshiswa kakhulu. Inkulu kangakanani isaphulelo? Ngokubanzi, nge-eriyan elungileyo, umgama uya kuba ngamaxesha ama-2 ubuncinci bubi. Kwakhona, ngaphezulu kwe-eriyali, eyona nto ibalulekileyo yokwamkela! Kutheni kunjalo? Kuba isibhakabhaka sanamhlanje sizaliswa yimiqondiso emininzi, ezi zimpawu zivimba ityhubhu yokufumana. Kuba isihluzo esingaphambili se-SEFT sibaluleke kangaka, senza njani isihluzi esingaphambili? I-RF Ishishini eliPhezulu lokufundisa! Nangona kunjalo, isihluzo esingaphambili seqela lama-435mhz akukho lula kakhulu ukuba songeze. Masiqale uhlalutyo
Le yiseti yeefiltha ze-chebysshev ze-Chebysshev kunye ne-canocing ephezulu yokudibanisa kunye ne-randered ye-435mhz. Ngenxa yokusetyenziswa kwezinto ezifumanekayo ze-chip ezifumanekayo zorhwebo (ezinexabiso le-Q ukuya kuthi ga kwi-70), ilahleko yokufakwa ilahleko inkulu kakhulu, ifikelela kwi-41DB, kwaye enye ijika iguqulwe ibe ngamaza amileyo). Ke ngoko, ubuntununtunu bomsebenzi buchaphazeleka kakhulu, kuba ubuntununtunu banxulumene ngokuthe ngqo nenqanaba lokuqala lenqanaba le-umyplices, nokuba i-tekg ye-amonition inokulawulwa yi-filter ye-filters iya kuthi ibe mandundu nge-11db. Ke kunqabile ukubona enye esetyenziswayo ngolu hlobo. Jonga lo mfanekiso kwakhona:
Gcina ezinye iiparamitha, umkhuseli utshintshwa yi-coil engcono emngxunyeni, nangona ivolumu inkulu, kodwa ilahleko yokufakelwa iba malunga ne -5, kodwa kusafuneka kakhulu ukwenza. Kuba: Ukudibanisa amandla okuphikisa phezulu kungu-0,2p, kunye nokuxhobisa kwale ndawo akulula ukuyithenga, ngenxa yoko unokutsala uCapacitor kwi-PCB, ezisa ubunzima kwimpumelelo ye-PCB, ezisa ubunzima kwimpumelelo ye-PCB, ezisa ubunzima kwimpumelelo. Nokuba i-12nh ingactor ayilungile kakhulu kumoya, kwaye kufuneka ibe ngumngxunya kwaye ingene, kwaye ayilunganga ukuba akukho mava angonelanga. Ukukhuphela kusankulu, iiparamitha zaloo zixhasi zinovelwano ngakumbi, kwaye utshintsho oluncinci luya kuchaphazela intsebenzo. Ke, kuthekani ukuba ungaqhubeka ukwandisa ixabiso le-Q lomqhubi, kwaye kukho indlela yokuqhubeka nokunciphisa ukungakwazi ukudibanisa? Emva koko hlamba i-bandwidth kancinci. Imeko iya kuba ngolu hlobo lulandelayo:
Ixabiso le-Q yale qatha liba li-1600, kwaye i-IcTence ihle kakhulu, le cebo linokuqinisekisa ukukhetha kunye nezinye izikhombisi, ukuba akukho ngqwalaselo yokusetyenziswa kwamandla kwi-IC, ngequbuliso kutsala umgama. Ukusebenza kakuhle, kodwa ubungakanani bukhulu kakhulu i-filter enkulu kakhulu
Uyilo olusebenzayo lweSpiral Filter yeli filtha ye-spilral, abantu abambalwa kwaye bambalwa abantu abaya kuyila i-China, kwaye isoftware inokudityaniswa kakuhle. Okokuqala, umfanekiso odlulileyo wazisa isihluzo seSPIRAL SIFELELWANO ZE-435mhz. Ngapha koko, iifilitha ezingcono kufuneka ziphulwe ngokungqongqo, siya kuyila umgangatho we-2-cavity ephezulu kunye neefilimu ezi-4 zomatshini wokuvavanya.
