Beddelka coaxial waa gudbinta makaanikada elektiroonigga ah ee loo isticmaalo in lagu beddelo calaamadaha RF hal kanaal oo loo beddelo mid kale.Dareemida noocaan ah waxaa si weyn loogu isticmaalaa xaaladaha jiheynta calaamadaha ee u baahan soo noqnoqoshada sare, awood sare, iyo waxqabadka RF sare.Waxa kale oo inta badan lagu isticmaalaa hababka tijaabada RF, sida anteenooyinka, isgaarsiinta dayax-gacmeedka, isgaarsiinta, saldhigyada saldhiga, avionics, ama codsiyada kale ee u baahan in calaamadaha RF laga beddelo gees ilaa gees kale.
Dekadda beddel
NPMT: oo macnaheedu yahay n-pole m-throw, halkaas oo n ay tahay tirada dekedaha wax soo saarka iyo m waa tirada dekedaha wax soo saarka.Tusaale ahaan, furaha RF oo leh hal deked oo wax-soo-saarka ah iyo laba dekedood oo wax-soo-saar ah waxaa loo yaqaannaa hal tiir oo laba jibbaaran, ama SPDT/1P2T.Haddii dareemaha RF uu leeyahay hal gelinta iyo 6 wax soo saar, markaa waxaan u baahanahay inaan doorano furaha SP6T RF.
Tilmaamaha RF
Caadi ahaan waxaanu tixgalinaa afar shay: Geli khasaare, VSWR, Go'doomin iyo Awood.
Nooca soo noqnoqda:
Waxaan dooran karnaa beddelka coaxial iyadoo loo eegayo inta jeer ee nidaamkayaga.Inta jeer ee ugu badan ee aan bixin karno waa 67GHz.Caadi ahaan, waxaan go'aamin karnaa inta jeer ee wareejinta coaxial iyadoo ku saleysan nooca xiriiriyaha.
Xidhiidhiyaha SMA: DC-18GHz/DC-26.5GHz
N Connector: DC-12GHz
2.92mm Connector: DC-40GHz/DC-43.5GHz
1.85mm Connector: DC-50GHz/DC-53GHz/DC-67GHz
Xidhiidhiyaha SC: DC-6GHz
Celceliska awoodda: Sawirka hoose waxa uu muujinayaa celceliska koronta db naqshadaynta furayaasha.
Voltage:
Dareeraha coaxial waxaa ka mid ah gariiradda korantada iyo magnetka, kaas oo u baahan danab DC si uu u dhaqaajiyo dariiqa RF ee u dhigma.Noocyada korantada ee sida caadiga ah loo isticmaalo shixnado coaxial waa sida soo socota: 5V.12V.24V.28V.Caadiyan macaamiishu si toos ah uma isticmaali doonaan danab 5V ah.Waxaan taageernaa ikhtiyaarka TTL si aan u oggolaano danab hooseeya sida 5v si loo xakameeyo beddelka RF.
Nooca wadista:
Failsafe: Marka aan la isticmaalin korantada kontoroolka dibadda, hal kanaal ayaa had iyo jeer qabanaya.Ku dar koronto dibadda ah, kanaalka RF waxaa loo qabtaa mid kale.Marka danabku gooyo, kanaalka hore ee RF ayaa shaqeynaya.
Qabashada: Dareemaha nooca dhejiska ah wuxuu u baahan yahay koronto joogto ah si uu u sii wado muujinta kanaalka RF.Ka dib markii sahayda korontadu ay baaba'do, dareewalku wuxuu ku sii jirayaa xaaladdiisii u dambaysay.
Caadi ahaan Furan: Habkan shaqo wuxuu kaliya u ansaxayaa SPNT.La'aanteed korantada xakamaynta, dhammaan kanaalada beddelka ma socdaan;Ku dar koronto dibadeed oo dooro kanaalka la cayimay ee furaha;Marka danab dibadda ah aan la isticmaalin, shiduhu wuxuu ku soo noqdaa xaalad aan dhammaan kanaalada soconayn.
Tilmaame: Shaqadani waxay caawisaa si loo muujiyo heerka beddelka.
