TS'ELISO HONA

Waveguide single directional crossguide coupler e na le li-waveguide tse peli tse ka letsohong le letona.

Ho kopanya ho finyelloa ka ho qala likoti tse peli tse nyenyane leboteng le tloaelehileng le pharaletseng la waveguide. Kamora moralo oa ntlafatso, matla a lets'oao a kopantsoeng le masoba ana a mabeli a kopanyang a ka khutlisoa 'me a hlakoloa. Likoti tsena hangata li entsoe ka lesoba le lenyenyane la sefapano ho fihlela ts'ebetso e nepahetseng.

A coupleal coupler ke karolo e behang lithapo tse peli tsa phetiso haufinyana e le hore matla a mothapo o mong a ka kopanngoa ho o mong. The coupler e bapisoa le impedance e ts'oanang likoung tsohle tse 'ne, e etsa hore ho be bonolo ho kenella lipotolohong tse ling kapa lits'ebetsong tse ling. Ka ho amohela meaho e fapaneng ea ho kopanya, mecha ea phatlalatso ea ho kopanya, le mekhoa ea ho kopanya, li-couplers tse loketseng mekhoa e fapaneng ea li-microwave tse nang le litlhoko tse fapaneng li ka etsoa.

Kopo:

Li-couplers tse tataisang, e le karolo ea bohlokoa ea lipotoloho tse ngata tsa microwave, 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 holim'a mefuta e mengata ea maqhubu.
1. Ka amplifier e leka-lekaneng, e thusa ho finyella tekanyo e ntle ea input-output voltage stand wave ratio (VSWR).
2. Ka li-mixer tse leka-lekaneng le lisebelisoa tsa microwave (tse kang li-analyzer tsa marang-rang), li ka sebelisoa ho etsa mohlala oa ketsahalo le lipontšo tse bonts'itsoeng.
3. Puisanong ea mehala, tšebeliso ea 90 ° bridge coupler e ka fumana phoso ea phase ea transmitter ea π/4 phase shift keying (QPSK).

Qualwavee fana ka li-broadband le li-couplers tsa crossguide tse nang le matla a phahameng ka mefuta e mengata ho tloha ho 1.13 ho isa ho 40GHz. Ho na le mefuta e fapaneng ea likou tsa waveguide, joalo ka WR-28 le WR-34. Li-couplers li sebelisoa haholo lits'ebetsong tse ngata.
Amohela bareki ho letsetsa le ho botsa.
