• Pakukamura chiratidzo kuita zviratidzo zviviri zveamplitude yakaenzana uye 90 ° kana 180 ° chikamu musiyano.
• Ye quadrature kubatanidza kana kuita muchidimbu/kusiyana kusanganisa.
Nhanganyaya
Couplers nemahybrids midziyo umo tambo mbiri dzekutapurirana dzinopfuura dziri pedyo nepedyo kuti simba ripararire pamutsara mumwe kuenda kune mumwe tambo. A 3dB 90 ° kana 180 ° hybrid inopatsanura chiratidzo chekupinza kuita maviri akaenzana amplitude inobuda. Iyo inotungamira coupler inowanzo patsanura chiratidzo chekuisa kuita maviri asina kuenzana amplitude zvinobuda. Izwi rokuti "directional coupler", "90 ° hybrid", uye "180 ° hybrid" rinobva pamusangano. Nekudaro, iyo 90 ° uye 180 ° mahybrids anogona kufungidzirwa se3 dB anotungamira vaviri. Pasinei nekufanana uku, maparamendi anoshandiswa kutsanangura kuyerera kwechiratidzo mune inotungamira vaviri vaviri uye mashandisiro, mukushandisa chaiko, akasiyana zvakakwana kuti ape pfungwa dzakasiyana.
180° Hybrids Inoshanda Tsananguro
A 180 ° hybrid inodzokororwa ina-port mudziyo inopa maviri akaenzana amplitude in-phase masiginecha painopihwa kubva kune yayo sum port (S) uye maviri akaenzana amplitude 180 ° kunze-kwe-chikamu masiginecha painopihwa kubva kune yayo musiyano port (D). Sezvineiwo, masiginecha anopinza mumachiteshi C uye D anozowedzera pachiteshi chemari (B) uye mutsauko wemasaini maviri uchaonekwa pamusiyano chiteshi (A). Mufananidzo 1 idhizaini inoshanda iyo ichashandiswa muchinyorwa chino kumiririra iyo 180 ° yakasanganiswa. Port B inogona kutariswa sum port uye port A ndiyo musiyano wechiteshi. Zviteshi A neB uye zviteshi C uye D zviteshi zviviri zvezviteshi.
90 ° MaHybrids kana mahybrid couplers anonyanya kuita 3 dB inotungamira vaviri umo chikamu cheiyo yakabatanidzwa inobuda chiratidzo uye inobuda siginecha yakaparadzana 90 °. Sezvo -3 dB inomiririra hafu yesimba, 3 dB coupler inogovanisa simba zvakaenzana (mukati meimwe kushivirira) pakati pezvinobuda uye zvakabatanidzwa zvinobuda ports. Iyo 90 ° chikamu musiyano pakati pezvinobuda inoita kuti mahybrids abatsire mukugadzirwa kwemagetsi anochinja-chinja attenuators, microwave mixers, modulators uye zvimwe zvakawanda microwave zvikamu uye masisitimu. Mufananidzo 5 unoratidza dhayagiramu yedunhu uye tafura yechokwadi iyo ichashandiswa mukutsanangura kushanda kweRF frequency 90 ° hybrid. Sezvinoonekwa kubva mumufananidzo uyu, chiratidzo chinoshandiswa kune chero chinopinza chinozoguma maviri akaenzana amplitude masaini ari quadrature, kana 90 °, kunze kwechikamu nemumwe. Zviteshi A neB nemaPorts C neD zvakaparadzaniswa. Sezvambotaurwa muchikamu che180 ° hybrid, iyo RF uye microwave frequency zvishandiso zvinoshandisa nzira dzakasiyana dzekuvaka. Kunyangwe mhinduro dzedzidziso dzakafanana, nzvimbo yechiteshi uye gungano zvakasiyana. Pazasi, muMufananidzo mune "cross-over" uye "non-crossover" shanduro dzakapihwa kune microwave frequency (500 MHz uye kumusoro) uye inoguma chokwadi tafura. Makumi mapfumbamwe emadhigirii mahybrids anodaidzwa zvakare kuti mahybrids equadrature nekuti chikamu chezvakabuda zviviri zvine quadrant (90°) zvakaparadzana. Ziva zvakare kuti hazviite mutsauko kuti ndechipi chiteshi chiri chiteshi chekupinza chero hukama pakati pezviteshi huchiripo. Izvi zvinodaro nekuti mahybrids e90 ° ane magetsi uye nemuchina anoenzanirana pamusoro peese maAxes eX neY.
Si Chuan Keenlion Microwave sarudzo yakakura ye3DB hybrid bhiriji mune narrowband uye Broadband masisitimu, inovhara ma frequency kubva 0.5 kusvika 50 GHz. Iwo akagadzirirwa kubata kubva pagumi kusvika pamakumi matatu ekuisa simba mu50-ohm transmission system. Microstrip kana stripline madhizaini anoshandiswa, uye akakwenenzverwa kuita zvakanaka.
Mauniti anouya akajairwa ane SMA kana N chidzitiro chekubatanidza, kana 2.92mm, 2.40mm, uye 1.85mm majoini epamusoro ma frequency ezvikamu.
Isu tinogona zvakare kugadzirisa iyo 3DB Hybrid Bridge zvinoenderana nezvaunoda. Iwe unogona kupinda peji rekugadzirisa kuti upe zvakatemwa zvaunoda.
