Mefuta e meholo ea li-couplers
Directional Coupler: E na le likou tse 'ne' me e ka tsamaisa karolo ea lets'oao la ho kenya ka lehlakoreng le leng sebakeng se itseng sa tlhahiso bakeng sa ho lekola matšoao le taolo ea maikutlo.
Power Divider: E fana ka matšoao a ho kenya likoung tse ngata tse hlahisoang ka tekanyo e lekanang, hangata e sebelisoang ka har'a li-antenna le litsamaiso tse ngata tsa likanale.
Hybrid Coupler: E ka arola lets'oao la ho kenya ka matšoao a mangata a phallo ea amplitude e lekanang empa mekhahlelo e fapaneng. E sebelisoa haholo ho li-phase shifters le li-amplifiers tse leka-lekaneng.
Lintlha tsa bohlokoa tsa coupler
Coupling Factor: E bonts'a karo-karolelano ea matla a lets'oao a amohetsoeng ke kou e kopanyang ho matla a kenyelletsoang, hangata a hlahisoang ka li-decibel (dB).
Ho itšehla thajana: E lekanya tekanyo ea ho itšehla thajana pakeng tsa likou tse sa sebelisoeng. Ha ho itšehla thajana ho phahame, ho na le tšitiso e nyane lipakeng tsa likou.
Tahlehelo ea ho Kena: e bolela tahlehelo ea matla ha lets'oao le feta har'a banyalani. Ho fokotseha ha tahlehelo ea ho kenya, ho phahamisa katleho ea phetisetso ea matšoao.
Standing wave ratio (VSWR): e bonts'a ho ts'oana ha boema-kepe ba coupler port. Ha VSWR e le haufi le 1, e ntlafatsa ts'ebetso e ts'oanang.
Libaka tsa kopo tsa couplers
Tlhokomelo ea matšoao: Lits'ebetsong tsa maqhubu a seea-le-moea, li-couplers li sebelisoa ho ntša karolo ea lets'oao bakeng sa ho lekola le ho lekanya ntle le ho ama phetiso ea lets'oao la mantlha.
Kabo ea matla: Ka letoto la li-antenna, li-couplers li sebelisetsoa ho tsamaisa matšoao ka mokhoa o lekanang ho likarolo tsa antenna ka bomong ho fihlela ho betla le taolo ea tataiso.
Taolo ea maikutlo: Lipotolohong tsa amplifier, li-couplers li sebelisoa ho ntša karolo ea lets'oao la tlhahiso le ho le khutlisetsa ho se kenyelletsoang ho tsitsisa phaello le ho ntlafatsa linearity.
Synthesis ea matšoao: Lits'ebetsong tsa puisano, li-couplers li ka sebelisoa ho kopanya matšoao a mangata hore e be lets'oao le le leng bakeng sa phetisetso le ts'ebetso e bonolo.
