Directional coupler imhando ye microwave mudziyo unoshandiswa zvakanyanya mu microwave system.Chinhu chayo ndechekugovera simba reiyo microwave chiratidzo mune imwe chikamu.
Directional couplers inoumbwa netambo dzekutumira.Coaxial mitsara, rectangular waveguides, denderedzwa waveguides, striplines uye microstrip mitsara zvese zvinogona kuumba inotungamira couplers.Naizvozvo, kubva pakuona kwechimiro, vanotungamira vanobatana vane huwandu hwakawanda hwemhando uye misiyano mikuru.Nekudaro, kubva pamaonero eiyo nzira yekubatanidza, inogona kupatsanurwa kuita mhando ina, dzinoti, pinhole coupling, parallel coupling, branching coupling uye kuenzanisa kaviri T.
A directional coupler inhengo inoisa mitsara miviri yekufambisa padhuze zvakaringana kune imwe neimwe kuitira kuti simba riri pamutsetse mumwe ribatanidzwe kune simba pane rimwe.Chiratidzo amplitude yezviteshi zvayo zviviri zvinobuda zvinogona kuenzana kana kusaenzana.Iyo coupler inoshandiswa zvakanyanya ndeye 3dB coupler, uye amplitude yezvinobuda zviratidzo zvezviteshi zvayo zviviri zvinobuda zvakaenzana.
Directional coupler chinhu chinotungamira simba rekubatanidza (kugovera) chinhu.Icho chikamu chechina chechiteshi, kazhinji chinoumbwa nemitsara miviri yekufambisa inonzi yakatwasuka (main line) uye coupling line (secondary line).Chikamu (kana chese) chesimba remutsetse wakatwasuka wakabatanidzwa kumutsara wekubatanidza kuburikidza neimwe nzira yekubatanidza (senge slots, maburi, kubatanidza mitsara zvikamu, nezvimwewo) pakati pemutsara wakatwasuka uye mutsara wekubatanidza, uye simba riripo. inodiwa kufambiswa chete kune imwe chiteshi chinobuda mumutsara wekubatanidza, nepo imwe chiteshi isina simba rinobuda.Kana iyo wave yekuparadzira gwara mumutsara wakatwasuka ukava wakatarisana negwara rekutanga, chiteshi chemagetsi chinobuda uye chisiri chemagetsi chinobuda mumutsara wekubatanidza chinochinjawo saizvozvo, ndiko kuti, simba rekubatanidza (kugovera) rinotungamira, saka ndizvo. inonzi directional coupler (directional coupler).
Sechikamu chakakosha cheakawanda microwave maseketi, anotungamira couplers anoshandiswa zvakanyanya mumazuva ano emagetsi masisitimu.Inogona kushandiswa kupa sampling simba rekubhadharisa tembiricha uye amplitude control maseketi, uye inogona kupedzisa kugovera kwemagetsi uye synthesis mune yakakura frequency renji;Mune yakaenzana amplifier, zvinobatsira kuwana yakanaka yekupinda uye inobuda voltage yakamira wave ratio (VSWR);Mune yakaenzana musanganisi uye microwave zvishandiso (semuenzaniso, network analyzer), inogona kushandiswa kuenzanisa chiitiko uye inoratidzwa masaini;Mukukurukurirana kwefoni, shandisa.
90 ° bhiriji coupler inogona kuona chikamu chikanganiso che π/4 phase shift keying (QPSK) transmitter.Iyo coupler inofananidzwa nehunhu impedance pamadoko ese mana, izvo zvinoita kuti zvive nyore kuiswa mune mamwe maseketi kana subsystems.Nekushandisa zvakasiyana-siyana zvekubatanidza zvimiro, kubatanidza masvikiro uye nzira dzekubatanidza, inotungamira couplers inokodzera zvakasiyana zvinodiwa zveakasiyana microwave masisitimu anogona kugadzirwa.
