Kwintsimi ye-RF kunye ne-microwave transmission yesignali, ukongeza kuthungelwano lwesignali engenazingcingo, uninzi lwazo lufuna iingcingo zothumelo zokuhanjiswa komqondiso, ezinemigca yecoaxial kunye namaza amaza asetyenziswa ngokubanzi ukuhambisa amandla e-microwave RF.
Imigca yothumelo lweWaveguide ineengenelo zelahleko ye-conductor ephantsi kunye ne-dielectric, umthamo wamandla amakhulu, akukho lahleko yemitha, ulwakhiwo olulula, kunye nokwenza lula.I-waveguides esetyenziswa ngokuqhelekileyo ibandakanya uxande, isetyhula, i-ridged enye, i-double ridged, kunye ne-elliptical.Okwangoku, ezona zikhokelo zisetyenziswa kakhulu ngamaza ngamaza oxande.
Kwinkqubo yokusetyenziswa kwezixhobo ze-waveguide, izixhobo ezininzi zihlala zifuna ukudityaniswa ngokuhambelanayo, kwaye uqhagamshelo phakathi kwezixhobo ze-waveguide ezikufutshane zihlala ziphunyezwa ngodibaniso oluhambelanayo lweeflange.
Njengeziqhagamshelo zeRF coaxial, ii-waveguides eziqhelekileyo kunye neeflange nazo zikumgangatho wehlabathi jikelele.Ngetheyibhile engezantsi, ungabuza amagama asemgangathweni ahambelanayo kunye neesayizi ezahlukeneyo zamaza oxande.
Ukusetyenziswa kweWaveguide Coaxial Converter
Ngokukwanjalo, iilayini ze-coaxial zikwazezona ntambo zothumelo zixhaphakileyo kwi-microwave kunye nobunjineli berediyo yerediyo, ezineempawu zebroadband ezinokusebenza ukusuka ngoku ngqo ukuya kwi-millimeter wave band, okanye nangaphezulu.Iintambo zothumelo lwe-coaxial zisetyenziswe ngokubanzi kwiinkqubo ze-microwave kunye namalungu e-microwave.
Kukho umahluko omkhulu kubungakanani, izinto eziphathekayo, kunye neempawu zothumelo phakathi kwemigca yokuhambisa i-coaxial kunye ne-waveguide.Nangona kunjalo, ngenxa yoluhlu olubanzi lwezicelo, iinjineli zeRF zihlala zidibana neemeko apho imigca emibini yothumelo kufuneka idityaniswe, ifuna abaguquli be-coaxial waveguide.
Iziguquli zeCoaxial waveguide zizixhobo ezibalulekileyo kwisixhobo semicrowave, umlinganiselo wemicrowave, iinkqubo zemicrowave, kunye nobunjineli.Iindlela zabo zokuguqula ikakhulu zibandakanya ukudibanisa umngxuma omncinci, ukudityaniswa kwe-probe, ukuguqulwa kokuguqulwa komgca wokugqibela, kunye nokuguqulwa kwe-ridge waveguide;Ukudibanisa i-coaxial probe yindlela yokuguqula esetyenziswa ngokubanzi phakathi kwabo.
Isiguquli se-waveguide coaxial ikakhulu siqukethe isiguquli sokuqala, isiguquli sesibini, kunye neflange, kunye namacandelo amathathu adityaniswe ngokulandelelana.Ngokuqhelekileyo kukho abaguquli be-orthogonal be-90 ° waveguide coaxial kwaye bapheliswe i-180 ° waveguide converters coaxial.Isiguquli se-coaxial waveguide sineempawu zebhendi yefrikhwensi ebanzi, ilahleko esezantsi yokufaka, kunye namaza okuma amancinci.I-bandwidth yomgca we-coaxial kunye ne-waveguide ibanzi xa ihanjiswa ngokulandelelana, kwaye i-bandwidth emva kokudibanisa ixhomekeke ekulungelelaniseni i-impedance ye-coaxial waveguide.
Uguqulo lweCoaxial waveguide luqhele ukusetyenziswa kwiinkqubo ezininzi zemicrowave, ezinje ngeeriyali, ii-transmitters, abamkeli, kunye nezixhobo zetheminali zokuthwala, ezinokuthi zisetyenziswe ngokubanzi kunxibelelwano lwesathelayithi, irada, unxibelelwano olungenacingo, imicrowave yeshishini, uvavanyo lwemicrowave kunye neenkqubo zokulinganisa, iinkqubo zonyango zemicrowave. , njl.
