Makomputa eDirectional imhando yakakosha yemudziyo wekugadzirisa masaini. Basa rawo guru nderekuyedza masaini eRF padanho rakatarwa rekubatanidza, nekuparadzaniswa kwakanyanya pakati pemakomputa esignal nemakomputa akatorwa — izvo zvinotsigira kuongorora, kuyerwa uye kugadziriswa kwemashandisirwo mazhinji. Sezvo ari madhizaini asingashande, anoshandawo nenzira yekumashure, nemasaini akapinzwa munzira huru zvichienderana negwara remudziyo uye mwero wekubatanidza. Kune misiyano mishoma muchimiro chemakomputa edirectional, sezvatichaona pazasi.
Tsanangudzo
Zvakanaka kuti coupler ive isina kurasikirwa, inoenderana uye inodzokororwa. Hunhu hwekutanga hwema network e-port matatu nemana ndeyekupatsanurana, kubatana uye kutungamira, izvo zvinoshandiswa kuratidza ma coupler. Coupler yakakodzera ine kutungamira nekudzivirirana kusingaperi, pamwe chete ne coupling factor yakasarudzwa pakushandiswa kwainotarisirwa.
Dhayagiramu inoshanda iri muMufananidzo 1 inoratidza mashandiro emuchina wekubatanidza madhairekitori, ichiteverwa netsananguro yema parameter ekushanda ane chekuita nawo. Dhayagiramu yepamusoro imuchina wekubatanidza madhoo mana, unosanganisira madhoo akabatana (ekumberi) neakasarudzika (ekumashure, kana akaratidzwa). Dhayagiramu yepasi ichimiro chemadhoo matatu, chinobvisa dhoo rakaparadzaniswa. Izvi zvinoshandiswa mumashandisirwo anongoda chete kuburitswa kwemuchina mumwe chete wekubatanidza madhoo. Muchina wekubatanidza madhoo matatu unogona kubatanidzwa munzira yekumashure, uko dhoo raimbobatanidzwa rinova dhoo rakaparadzaniswa:
Mufananidzo 1: Yekutangachinobatanidza chinotungamiramagadzirirwo
Hunhu hwekushanda:
Coupling Factor: Izvi zvinoratidza chikamu chesimba rekupinda (paP1) rinoendeswa kuchiteshi chakabatana, P3
Kutungamira: Ichi chiyero chekukwanisa kwemuchina wekubatanidza kuparadzanisa mafungu anopararira munzira dzekumberi nedzekumashure, sezvinoonekwa pazviteshi zvakabatana (P3) nezvakaparadzaniswa (P4)
Kupatsanurwa: Kunoratidza simba rinoendeswa kumutoro usina kusanganiswa (P4)
Kurasikirwa Nekupinza: Izvi zvinotsanangura simba rekupinda (P1) rinoendeswa kuchiteshi chinotumirwa (P2), iro rinoderedzwa nesimba rinoendeswa kumachiteshi akabatana uye akaparadzaniswa.
Hunhu hwezvinhu izvi mu dB ndehwekuti:
Kubatanidza = C = 10 log (P1/P3)
Kutungamira = D = 10 log (P3/P4)
Kuzviparadzanisa = I = 10 log (P1/P4)
Kurasikirwa Kwekuisa = L = 10 log (P1/P2)
Mhando dzeVanobatanidza
Rudzi urwu rwe coupler rune ma ports matatu anowanikwa, sezvakaratidzwa muFig. 2, apo port yechina inogumiswa mukati kuti ipe hutungamiriri hwakanyanya. Basa guru re coupler redirectional nderekuyedza chiratidzo chakaparadzaniswa (reverse). Kushandiswa kwakajairika kuyerwa kwesimba rinoratidzwa (kana zvisina kunanga, VSWR). Kunyangwe ichigona kubatanidzwa ne reverse, rudzi urwu rwe coupler harudzokorore. Sezvo imwe yema ports akabatana ichigumiswa mukati, chiratidzo chimwe chete chakabatana chinowanikwa. Munzira yekumberi (sezvakaratidzwa), coupled port inoyedza reverse wave, asi kana yakabatana ne reverse direction (RF Input kurudyi), coupled port ingave muenzaniso we forward wave, yakaderedzwa ne coupling factor. Nekubatana uku, mudziyo unogona kushandiswa se sampler yekuyera chiratidzo, kana kuendesa chikamu che output signal ku feedback circuitry.
Mufananidzo 2: Chinobatanidza Chinongedzera che50-Ohm
Zvakanakira:
1. Kushanda kunogona kugadziriswa kuti nzira ifambe mberi
2, High direction uye kuzviparadzanisa
3. Kutungamira kwe coupler kunokanganiswa zvakanyanya ne impedance match inopiwa ne termination pa raundi port. Kuisa termination iyoyo mukati kunoita kuti termination ishande zvakanaka.
Zvakashata:
1. Kubatanidza kunowanikwa chete munzira yekuenda mberi
2, Hapana mutsetse wakabatana
3. Simba rechiteshi chakabatana riri pasi pechiteshi chekupinda nekuti simba rinoshandiswa pachiteshi chakabatana rinenge ranyangarika zvachose mukati mekupedzisira kwemukati.
Si Chuan Keenlion Microwave ine sarudzo yakakura yeDirectional Coupler mu narrowband uye broadband configurations, inofukidza ma frequency kubva pa 0.5 kusvika 50 GHz. Yakagadzirwa kuti ikwanise kubata simba rekupinda re10 kusvika 30 watts mu 50-ohm transmission system. Madhizaini eMicrostrip kana stripline anoshandiswa, uye akagadzirwa kuti ashande zvakanaka.
