1.Esimisweni se-microwave, ngokuvamile kudingekile ukuhlukanisa umzila owodwa wamandla e-microwave eziteshini eziningana ngokulingana, okuyinkinga yokusabalalisa amandla.Izingxenye eziqaphela lo msebenzi zibizwa ngokuthi izingxenye zokusabalalisa amandla, ikakhulukazi ezihlanganisa i-directional coupler, isihlukanisi samandla kanye namadivayisi ahlukahlukene egatsha le-microwave.Lezi zingxenye ngokuvamile ziwumugqa wamanethiwekhi wezinsimbi eziningi, ngakho ithiyori yenethiwekhi ye-microwave ingasetshenziselwa ukuhlaziya.I-coupler eyisiqondiso iyisici esinezimbobo ezine ezinezici zokudlulisela eziqondisayo.Yakhiwe ngamapheya amabili wezinhlelo zokudlulisela ezixhunywe ngamadivaysi okuhlanganisa.
2.Ukuhlukaniswa kusekelwe ekuphumeni kokuhlanganisayo, okuhlanganisa i-co-directional coupler kanye ne-coupler ebuyela emuva.Ngokohlobo lwayo lokudlulisela, ingahlukaniswa ibe i-waveguide directional coupler, i-coaxial directional coupler, i-stripline noma i-microstrip directional coupler.Ngokwamandla abo okuhlanganisa, angahlukaniswa abe ama-couplers aqondisayo aqinile kanye nama-couplers aqondile abuthakathaka.Ngokuvamile, izibhangqwana eziqondisayo ezifana ne-0dB kanye ne-3dB zingamabhangqa aqinile, ama-couplers aqondisayo afana no-20dB kanye no-30dB amabhangqa abuthaka, futhi ama-couplers aqondisayo anobubanzi be-dB angamabhangqana aphakathi nendawo ahlanganayo.Ngokwamandla azo okuthwala, angahlukaniswa abe ama-couplers aqondisa amandla aphansi kanye nama-coupleal aqondisa amandla aphezulu.Ngokwesigaba sokukhiphayo sedivayisi, kukhona i-coupler eqondisayo engu-90 °.
3.Inkomba yokusebenza Inkomba yokusebenza ye-coupleal eqondisayo: i-coupling degree isolation degree orientation degree okokufaka kwesilinganiso segagasi elisebenzayo umkhawulokudonsa
