Directional coupler ke mofuta oa sesebelisoa sa microwave se sebelisoang haholo tsamaisong ea microwave.Mohloli oa eona ke ho aba matla a lets'oao la microwave ka tekanyo e itseng.
Li-couplers tsa Directional li entsoe ka lithapo tsa phetiso.Li-coaxial lines, li-waveguide tse khutlonnetsepa, li-waveguide tse chitja, li-stripline le li-microstrip kaofela li ka etsa li-couplers tse lebang tsela.Ka hona, ho ea ka pono ea sebopeho, banyalani ba tataiso ba na le mefuta e mengata ea mefuta le phapang e kholo.Leha ho le joalo, ho latela mokhoa oa eona oa ho kopanya, e ka aroloa ka mefuta e mene, e leng, pinhole coupling, parallel coupling, branching coupling le matching habeli T.
Coupulier ea tataiso ke karolo e behang likhoele tse peli tsa phetiso haufi ka ho lekana e le hore matla a moleng o le mong a ka kopanngoa le matla ho o mong.Bophahamo ba matšoao a likou tsa eona tse peli tse hlahisoang bo ka lekana kapa ha bo lekane.Coupupr e sebelisoang haholo ke 3dB coupler, 'me boholo ba matshwao a tlhahiso ea likoung tsa eona tse peli tsa tlhahiso ea lekana.
Directional coupler ke karolo ea tataiso ea matla a ho kopanya (kabo).Ke karolo e mene ea koung, hangata e entsoe ka mela e 'meli ea phetiso e bitsoang mola o otlolohileng (mohala o moholo) le mohala o kopanyang (mohala oa bobeli).Karolo (kapa kaofela) ea matla a mohala o otlolohileng o kopantsoe le mohala oa ho kopanya ka mokhoa o itseng oa ho kopanya (joalo ka li-slots, masoba, likaroloana tsa ho kopanya, joalo-joalo) pakeng tsa mohala o otlolohileng le oa ho kopanya, 'me matla a teng. e hlokehang ho fetisetsoa boema-kepe bo le bong feela moleng o kopanyang, ha kou e 'ngoe e se na tlhahiso ea matla.Haeba tataiso ea phallo ea maqhubu moleng o otlolohileng e fetoha e fapaneng le ea pele, boema-kepe ba tlhahiso ea matla le boema-kepe bo sa hlahisoang ke matla moleng oa coupling le tsona li tla fetoha ka tsela e nepahetseng, ke hore, matla a ho kopanya (kabo) a tataisoa, kahoo ho joalo. e bitsoang directional coupler (directional coupler).
E le karolo ea bohlokoa ea lipotoloho tse ngata tsa microwave, li-couplers tse tataisang li sebelisoa haholo lits'ebetsong tsa sejoale-joale tsa elektroniki.E ka sebelisoa ho fana ka matla a sampole bakeng sa matšeliso a mocheso le li-circuits tsa taolo ea amplitude, 'me e ka phethela kabo ea matla le synthesis ka mefuta e mengata ea maqhubu;Ho amplifier e leka-lekaneng, hoa thusa ho fumana tekanyo e ntle ea ho kenya letsoho le ho tsoa ho matla a motlakase (VSWR);Motsoakong o leka-lekaneng le lisebelisoa tsa microwave (mohlala, analyzer ea marang-rang), e ka sebelisoa ho etsa sampole ketsahalo le matšoao a bonts'itsoeng;Puisanong ea mehala, sebelisa.
90 ° bridge coupler e ka fumana phoso ea mohato oa π/4 phase shift keying (QPSK) transmitter.The coupler e bapisoa le impedance ea sebopeho likoung tsohle tse 'ne, e etsang hore ho be bonolo ho kenngoa lipotolohong tse ling kapa lits'ebetsong tse ling.Ka ho sebelisa mekhoa e fapaneng ea ho kopanya, mekhoa ea ho kopanya le mekhoa ea ho kopanya, li-couplers tse loketseng litlhoko tse fapaneng tsa litsamaiso tse fapaneng tsa microwave li ka etsoa.
