Wareegyada cod-weyneeye waxay door muhiim ah ka ciyaaraan aaladaha elegtarooniga ah ee aan la tirin karin, laga bilaabo cod-weyneyaasha muusiga ilaa kuwa gudbiyaha.Fahamka astaamahooda iyo hawlahooda ugu muhiimsan ayaa muhiim u ah hiwaayad kasta oo elegtaroonig ah ama xirfadle.Balooggan, waxaanu ku dhex daadagi doonaa adduunka xiisaha leh ee wareegyada cod-weyneeye, anagoo sahameyna sifooyinkooda ugu muhiimsan, mabaadi'da hawlgalka, iyo codsiyada.Markaa haddii aad tahay arday xiiseeya ama aad tahay injineer hiigsi leh, isku xidhka markaan galeyno safarkan wax-ku-oolka ah.
Waa maxay wareegtada cod-weyneeye?
Inta aynaan guda galin sifadooda, aynu marka hore qeexno waxa aynu uga jeedno wareegga cod-weyneeye.Si fudud loo dhigo, wareegga korantadu waa wareeg elektaroonik ah oo kor u qaada calaamadaha korantada ilaa heer sare oo awood ah oo ku habboon wadista rarka, sida afhayeenka ama anteenada.Caadi ahaan, wareegyada cod-weyneyayaashu waxay qaataan calaamad maqal ah oo hooseeya ama soo noqnoqoshada raadiyaha waxayna si weyn u xoojiyaan si ay u bixiyaan awoodda lagama maarmaanka u ah codsiga loogu talagalay.
Astaamaha wareegga korantada cod-weyneeye
1. Awooda wax ka qabashada awooda: Wareegyada cod-weyneyaasha waxaa loogu talagalay in lagu xakameeyo heerarka sare ee korantada marka loo eego noocyada kale ee cod-weyneyaasha.Awoodda ay ku bixiyaan awood muhiim ah waxay u saamaxdaa inay si hufan oo la isku halleyn karo u kaxeeyaan culaysyada culus.
2. Linearity: amplifiers korantadu waxay ku dadaalaan inay si sax ah u ilaashadaan qaabka iyo tafaasiisha calaamada gelinta.Khadka tooska ah ayaa muhiim u ah yaraynta qallooca iyo hubinta in si daacad ah u taranto calaamadii asalka ahayd.
3. Hufnaanta: Hufnaantu waa tixgalinta muhiimka ah ee wareegyada cod-weyneeye sababtoo ah waxay go'aamisaa beddelka awoodda korantada ee awoodda wax soo saarka ee waxtarka leh.Cod-weyneyaasha awoodda-sare ee waxtarka leh waxay yareeyaan wasakhda korantada, si ay u yareeyaan isticmaalka batteriga iyo daadinta kulaylka.
4. Bandwidth: Xadhkaha xadhkaha xawaaladaha korantada waxa loola jeedaa inta jeer ee uu si daacad ah u kordhin karo.Iyada oo ku xidhan arjiga, cod-weyneyayaashu waxa loo kala saari karaa sida cod-weyneeyeyaal awood maqal ah oo ka dhex shaqeeya baaxadda maqalka, ama cod-weyneyaasha tamarta soo noqnoqda ee raadiyaha loo isticmaalo hababka isgaarsiinta wireless-ka.
Hawlaha ugu muhiimsan ee wareegga korantada
1. Kor-u-qaadista isha: Shaqada ugu weyn ee wareegtada korantadu waa in ay kor u qaaddo signalka ilaa heer sare oo awood ah si ay uga adkaato culayska culayska, sida af-hayeenka ama anteenada.Cod-weyneyayaashu waxay ilaalinayaan daacadnimada iyo tayada calaamadda gelinta iyadoo la siinayo awood ku filan oo lagu wado culeyska.
2. Isbarbardhigga Impedance: Wareegyada cod-weyneeyeyaasha waxaa inta badan lagu qalabeeyaa shabakad isbarbardhigeysa impedance si kor loogu qaado wareejinta awoodda u dhexeysa cod-weyneeye iyo culeyska.Tani waxay hubinaysaa in awoodda ugu badan la gudbiyo, iyadoo yaraynaysa milicsiga iyo luminta calaamadaha.
3. Xakamaynta calaamadaha: Cod-weyneyayaashu waxay ka koobnaan karaan marxalado qaboojinta signalada si kor loogu qaado tayada signalka galinta, meesha laga saaro buuqa, ama lagu dabaqo shaandhayn gaar ah si loogu habeeyo wax soo saarka codsi gaar ah.Marxaladahaan waxaa ka mid noqon kara cod-sameeyayaal, barbareeyayaal, ama filtarrada.
4. Wareegga ilaalinta: Wareegyada cod-weyneyayaashu waxay inta badan leeyihiin wareegyada ilaalinta si ay uga hortagaan waxyeelada ka iman karta danab xad dhaaf ah, hadda, ama kulaylka.Hababkan ilaalinta ayaa gacan ka geysta kordhinta nolosha cod-weyneeye iyadoo la hubinayo hawlgal ammaan ah.
Gabagabo
Si loo soo koobo, wareegyada cod-weyneyayaashu waa qaybo aan laga maarmi karin oo ku jira codsiyada maqalka iyo RF ee kala duwan.Sifooyinkooda, sida maaraynta awoodda, linearity, hufnaanta, iyo bandwidth, waxay qeexaan awoodooda waxqabad.Fahamka hawlaha ugu muhiimsan ee cod-weyneyaasha, oo ay ku jiraan kor u qaadida calaamadaha, is-waafajinta impedance, qaboojinta calaamadaha iyo ilaalinta, waxay noo ogolaaneysaa inaan qadarin muhiimaddooda ku-hadalka wadista, gudbinta calaamadaha iyo bixinta khibrad maqal oo tayo sare leh.Marka ay tignoolajiyadu horumarto, cod-weyneyaasha korantadu waxay sii wadaan inay horumariyaan si ay u bixiyaan waxqabad weyn, hufnaan, iyo kala-duwanaansho codsiyo badan oo elektaroonig ah.
