1.Mokhoeng oa microwave, hangata hoa hlokahala ho arola mocha o le mong oa matla a microwave ka litsela tse 'maloa ka tekanyo, e leng bothata ba kabo ea matla.Likarolo tse hlokomelang ts'ebetso ena li bitsoa likarolo tsa kabo ea matla, haholo-holo ho kenyelletsa li-coupler tsa tataiso, divider ea motlakase le lisebelisoa tse fapaneng tsa makala a microwave.Likarolo tsena hangata ke marang-rang a li-multi-port mutual instrument networks, kahoo khopolo ea marang-rang ea microwave e ka sebelisoa bakeng sa tlhahlobo.Directional coupler ke ntho e nang le likou tse 'ne e nang le litšobotsi tsa phetiso ea tataiso.E entsoe ka lipara tse peli tsa litsamaiso tsa phetisetso tse hokahantsoeng ka lisebelisoa tse kopanyang.
2.Karohano e ipapisitse le tataiso ea tlhahiso ea coupling, ho kenyeletsoa co-directional coupler le reverse directional coupler.Ho latela mofuta oa phetiso ea eona, e ka aroloa ka waveguide directional coupler, coaxial directional coupler, stripline kapa microstrip directional coupler.Ho ea ka matla a bona a ho kopanya, ba ka aroloa ka li-couplers tse matla tsa ho kopanya le tse fokolang tsa tataiso.Ka kakaretso, li-couplers tse kang 0dB le 3dB ke li-couplers tse matla, li-couplers tse kang 20dB le 30dB ke li-couplers tse fokolang, 'me li-couplers tse nang le bophara ba dB ke li-couplers tse mahareng tse lebang tsela.Ho ea ka matla a bona a ho jara, li ka aroloa ka li-couplers tsa tataiso ea matla a tlase le li-couplers tse tsamaisang matla a phahameng.Ho ea ka karolo ea tlhahiso ea sesebelisoa, ho na le 90 ° directional coupler.
