Coupler chishandiso chinoshandiswa kufambisa masaini pakati pemaseketi akasiyana kana masisitimu. Inoshandiswa zvakanyanya muredhiyo frequency uye microwave minda. Basa rayo guru nderekubatanidza chimwe chikamu chesimba kubva patambo huru yekufambisa kuenda kune yechipiri mutsara kuti uwane kugovera chiratidzo, kutarisa kana mhinduro.
Mashandiro anoita coupler
Vakaroorana vanowanzo sanganisira mitsara yekufambisa kana waveguide zvimiro, izvo zvinoendesa chikamu chesimba rechiratidzo mumutsara mukuru kuenda kuchiteshi chekubatanidza kuburikidza nekubatanidza maitiro emagetsi emagetsi. Iyi nzira yekubatanidza haizokanganisa zvakanyanya kufambiswa kwechiratidzo chemutsara mukuru, kuve nechokwadi chekushanda kwakajairika kwehurongwa.
Main mhando couplers
Directional Coupler: Iyo ine zviteshi zvina uye inokwanisa kubatanidza chikamu chechiratidzo chekuisa kune chaiyo inobuda chiteshi chekutarisa chiratidzo uye kutonga kwemhinduro.
Power Divider: Inogovera masaini ekuisa kune akawanda anobuda madoko muzvikamu zvakaenzana, anowanzo shandiswa muantenna arrays uye akawanda-channel masisitimu.
Hybrid Coupler: Inogona kupatsanura chiratidzo chekuisa mune akawanda anobuda masaini akaenzana amplitude asi akasiyana nhanho. Inoshandiswa zvakanyanya muchikamu chekuchinja uye kuenzanisa amplifiers.
Key parameters ye coupler
Coupling Factor: Inoratidza chiyero chesimba rechiratidzo rinogamuchirwa nechiteshi chekubatanidza kune simba rekuisa, rinowanzo kuratidzwa muma decibels (dB).
Isolation: Inoyera dhigirii rechiratidzo chekuzviparadzanisa pakati pezvisina kushandiswa zviteshi. Iyo yakakwirira yekuzviparadzanisa, kudiki kupindira pakati pezviteshi.
Insertion Loss: inoreva kurasikirwa kwesimba kana chiratidzo chichipfuura nemu coupler. Iyo yakaderera kurasikirwa kwekuisa, iyo yakakwirira yekufambisa kwechiratidzo kushanda zvakanaka.
Yakamira wave ratio (VSWR): inoratidza iyo impedance inoenderana neye coupler port. Iyo padyo neVSWR ndeye 1, zvirinani kuita kwekuenzanisa.
Nzvimbo dzekushandisa dze couplers
Signal monitoring: Muredhiyo frequency masisitimu, macouplers anoshandiswa kubvisa chikamu chechiratidzo chekutarisa uye kuyerwa pasina kukanganisa kutapurirana kwechiratidzo chikuru.
Kugovera magetsi: Mune antenna array, macouplers anoshandiswa kugovera zvakaenzana masaini kune ega antenna zvinhu kuti uwane bheji uye kutungamira kudzora.
Feedback control: Mumaseketi amplifier, macouplers anoshandiswa kuburitsa chikamu chechiratidzo chekubuda uye kuchidzosera kune chekuisa kudzikamisa kuwana uye kugadzirisa mutsara.
Signal synthesis: Mune masisitimu ekutaurirana, macouplers anogona kushandiswa kugadzira akawanda masaini muchiratidzo chimwe chete kuti zvive nyore kutapurirana uye kugadzirisa.
Kufambira mberi kwetekinoroji
Nekukurumidza kusimudzira kwehunyanzvi hwekutaurirana, izvo zvinodiwa zvekushanda kwevaviri maererano nepamusoro frequency, simba repamusoro uye yakakura bandwidth iri kuramba ichiwedzera. Mumakore achangopfuura, michina ye coupler yakavakirwa pazvishandiso zvitsva uye mitsva mitsva yakaramba ichibuda, ine yakaderera yekuisa kurasikirwa, yakakwirira yekuzviparadzanisa uye yakakura yekushanda frequency band, kusangana nezvinodiwa zve5G kutaurirana, radar masisitimu, satellite kutaurirana uye mamwe minda.
mukupedzisa
Sechinhu chakakosha muRF uye microwave masisitimu, vaviri vanobatana vanoita basa rakakosha mukufambisa kwemasaini, kugovera uye kutarisa. Kunzwisisa kwayo kushanda musimboti, mhando, akakosha paramita uye nzvimbo dzekushandisa zvichabatsira kusarudza iyo yakakodzera coupler uye optimize mashandiro ehurongwa mumapurojekiti chaiwo.
