I-Band-Band Directional Coupler 698-2700MHz N
I-Telsto Wide band Directional couplers ibonelela ngokudityaniswa okucaba kwendlela yomqondiso ukuya kwelinye kwicala elinye kuphela (eyaziwa ngokuba ngumyalelo).Ngokuqhelekileyo ziquka umgca oncedisayo odibanisa umbane kumgca oyintloko.Esinye isiphelo somgca oncedisayo sifakwe ngokusisigxina kunye nokupheliswa okuhambelanayo.I-Directive (umahluko phakathi kokudibanisa kwelinye icala xa kuthelekiswa nelinye) malunga ne-20 dB kwi-couplers, i-Directional couplers isetyenziswa nanini na xa inxalenye yomqondiso ifuna ukwahlulwa okanye imiqondiso emibini kufuneka idityaniswe.I-Telsto ibonelela ngebhendi emxinwa kunye nebhanti engenazingcingo ezidibanisa umkhombandlela kunye nokudibanisa ukusuka kwi-3 dB ukuya kwi-50 dB okanye ngaphezulu.

Imiyalelo yokuFakelwa kwe-N okanye 7/16 okanye 4310 1/2″ intambo eguquguqukayo kakhulu
Ulwakhiwo lwesiqhagamshelo: ( Fig1 )
A. ngaphambili nut
B. umqolo nut
C. gasket
Imilinganiselo yokuhluthwa njengoko iboniswe ngumzobo (i-Fig2), ingqalelo kufuneka ihlawulwe ngelixa ihlubula:
1. Umphezulu wesiphelo somqhubi wangaphakathi kufuneka uhlanjululwe.
2. Susa ukungcola okufana nesikali sobhedu kunye ne-burr kwindawo yokugqibela yentambo.
Ukudibanisa indawo yokutywina: Khiya indawo yokutywina ecaleni komqhubi wangaphandle wentambo njengoko kubonisiwe kwidayagram (Fig3).
Ukudibanisa i-nut yangasemva (Fig3).
Dibanisa i nut yangaphambili nasemva ngokukruqula njengoko kubonisiwe kwidayagram ( Figs(5)
1. Ngaphambi kokujija, gcoba umaleko wegrisi yokuthambisa kwi-o-ring.
2. Gcina i-nut yangasemva kunye nentambo ingashukumi, Screw kumzimba weqokobhe elikhulu kumzimba weqokobhe elingasemva.Krwela ezantsi iqokobhe elikhulu lomzimba weqokobhe elingasemva usebenzisa isikrufu senkawu.Ukudibanisa kugqityiwe.
