Intshayelelo emfutshane
I-coupler ye-Directional luhlobo lwesixhobo se-microwave esisetyenziswa kakhulu kwinkqubo ye-microwave.Undoqo wayo kukusasaza amandla omqondiso we-microwave kumlinganiselo othile.
Ii-couplers ezithe ngqo zenziwe ngeentambo zothumelo.Imigca ye-coaxial, i-rectangular waveguides, i-wave waveguides, i-striplines kunye nemigca ye-microstrip zonke zinokwenza i-couplers eyalathiswayo.Ngoko ke, ukusuka kumbono wesakhiwo, izibini ezihambelanayo zineentlobo ezininzi kunye nokwahlukana okukhulu.Nangona kunjalo, ngokwembono yendlela yokudibanisa, inokohlulwa ibe ziindidi ezine, ezizezi, ukudityaniswa kombhobho, ukudibanisa okunxuseneyo, ukudityaniswa kwe-branching kunye nokuthelekisa i-T ephindwe kabini.
I-coupler eyalathiswayo licandelo elibeka imigca emibini yothumelo esondelelene ngokwaneleyo ukuze amandla kumgca omnye adityaniswe kumandla kwenye.I-amplitude yesignali yee-port zayo ezimbini zemveliso zinokulingana okanye zingalingani.I-coupler esetyenziswa ngokubanzi yi-3dB coupler, kwaye i-amplitude yemiqondiso yemveliso yamazibuko ayo amabini emveliso iyalingana.
I-coupler ye-Directional yinto yokudibanisa amandla (ukuhanjiswa).Licandelo lezibuko ezine, ngokuqhelekileyo liqulunqwe ngeentambo ezimbini zothumelo ezibizwa ngokuba ngumgca othe ngqo (umgca omkhulu) kunye nomgca wokudibanisa (umgca wesibini).Inxalenye (okanye yonke) yamandla omgca othe ngqo idityaniswe kumgca wokudibanisa ngendlela ethile yokudibanisa (ezifana neendawo zokubeka, imingxuma, iisegmenti zomgca wokudibanisa, njl. njl.) phakathi komgca othe tye kunye nomgca wokudibanisa, kwaye amandla ifunwa ukuhanjiswa kuphela kwelinye izibuko lemveliso kumgca wokudibanisa, ngelixa elinye izibuko lingenamveliso yamandla.Ukuba isalathiso sosasazo lwamaza kumgca othe tye siba ngokuchaseneyo necala loqobo, izibuko lemveliso yamandla kunye nezibuko elingaphumiyo lamandla kumgca wodibaniso nazo ziya kutshintsha ngokufanelekileyo, oko kukuthi, ukudibanisa amandla (ulwabiwo) lukwalathiso, ngoko kunjalo. ebizwa ngokuba yi-directional coupler (i-coupler yolwalathiso).
Njengenxalenye ebalulekileyo yeesekethe ezininzi ze-microwave, ii-couplers ezikhokelayo zisetyenziswa ngokubanzi kwiinkqubo zombane zanamhlanje.Ingasetyenziselwa ukubonelela amandla okusampula kwimbuyekezo yeqondo lokushisa kunye neesekethe zokulawula i-amplitude, kwaye inokugqiba ukuhanjiswa kwamandla kunye nokudibanisa kwi-wide frequency range;Kwi-amplifier elungeleleneyo, kuyanceda ukufumana igalelo elilungileyo kunye nemveliso ye-voltage stand wave ratio (VSWR);Kwi-mixer elungeleleneyo kunye nezixhobo ze-microwave (umzekelo, i-analyzer yenethiwekhi), ingasetyenziselwa ukusampula isiganeko kunye nezibonakaliso ezibonakalisiweyo;Kunxibelelwano lweselula, sebenzisa.
90 ° ibhulorho coupler inokumisela impazamo yesigaba se-π/4 isigaba shift keying (QPSK) transmitter.I-coupler ihambelana ne-impedance yeempawu kuwo onke amazibuko omane, okwenza kube lula ukufakwa kwezinye iisekethe okanye ii-subsystems.Ngokusebenzisa iindlela ezahlukeneyo zokudityaniswa, iindlela zokudibanisa kunye neendlela zokudibanisa, ii-couplers ezihambelanayo ezifanelekileyo kwiimfuno ezahlukeneyo zeenkqubo ezahlukeneyo ze-microwave zinokuyilwa.
