1.Kwinkqubo ye-microwave, kuhlala kuyimfuneko ukwahlula itshaneli enye yamandla e-microwave kwiitshaneli ezininzi ngokulinganayo, okuyingxaki yokuhanjiswa kwamandla.Amalungu aqondayo lo msebenzi abizwa ngokuba ngamacandelo osasazo lwamandla, ikakhulu aquka i-coupler ekhokelayo, isahluli samandla kunye nezixhobo ezahlukeneyo zesebe le-microwave.La macandelo aqhelekile angqamene nesixhobo sothungelwano sesixhobo se-multi-port mutual network, ngoko ithiyori yothungelwano lwe-microwave ingasetyenziselwa uhlalutyo.I-coupler ye-Directional yinto enezibuko ezine kunye neempawu zokuhambisa umkhombandlela.Iqulunqwe ngamaqela amabini eenkqubo zothumelo eziqhagamshelwe zizixhobo zokudibanisa.
2.Ukuhlelwa kusekelwe kwi-coupling output direction, kubandakanywa i-co-directional coupler kunye ne-reverse directional coupler.Ngokohlobo lwayo lothumelo, inokwahlulwa ibe yi-waveguide directional coupler, i-coaxial directional coupler, i-stripline okanye i-microstrip directional coupler.Ngokwamandla abo okudibanisa, banokwahlulwa babe ngamaqabane anxibelelanayo anamandla kunye nee-couplers ezibuthathaka.Ngokubanzi, i-couplers eyalathiswayo efana ne-0dB kunye ne-3dB zi-couplers ezinamandla, i-couplers eyalathiswayo efana ne-20dB kunye ne-30dB zi-couplers ezibuthathaka, kwaye i-couplers eyalathiswayo enobubanzi be-dB ngamaqabane aphakathi adibanisayo aphakathi.Ngokwamandla abo okuthwala, banokwahlulwa babe ngamaqabane angaphantsi kwamandla asezantsi kunye ne-couples yamandla aphezulu.Ngokwesigaba semveliso yesixhobo, kukho i-90 ° ye-coupler yesalathiso.
3.Isalathiso sokuSebenza kwesalathiso sokusebenza kwe-coupler eyalathiswayo: ukudityaniswa kwesidanga sokwahlula isidanga sokuqhelaniswa nesidanga igalelo elima wave ratio yokusebenza bandwidth
