umdibanisi
Icandelo lokusasazwa kwamandla lokwahlula isignali ye-RF ibe ziitshaneli ezimbini ngokomlinganiselo kwaye uyikhuphele kwinkqubo ye-antenna feeder

Izicelo eziphambili
(1) Ukusetyenziswa kwisekethe yelogic
I-coupler inokwenza iisekethe ezahlukeneyo ze-logic. Ngenxa yokuba ukusebenza kwe-coupler okuchasene nokuphazamiseka kunye nokwahlulwa kwayo kungcono kunokwe-transistor, isekethe ye-logic eyenziwe yiyo inokuthenjwa ngakumbi.
Amasimi esicelo kunye neziganeko ze-coupler
(2) Isicelo njengeswitshi yesimo esiqinileyo
Kwisekethe yokutshintsha, kudla ngokufuneka ukuba kubekho ukwahlulwa kombane okuhle phakathi kwesekethe yokulawula kunye neswitshi, nto leyo enzima kwiswitshi ye-elektroniki ngokubanzi, kodwa kulula ukuyiqonda nge-coupler.
(3) Ukusetyenziswa kwisekethe ye-trigger
Xa i-coupler isetyenziswa kwisekethe yokuphuma ebhistable, ingxaki yokuzahlula phakathi kokuphuma kunye nomthwalo ingasonjululwa ngempumelelo kuba i-LED inokudityaniswa ngokulandelelana kwisekethe yokuphuma yeetyhubhu ezimbini ngokulandelanayo.
(4) Ukusetyenziswa kwisekethe yokukhulisa i-pulse
Ii-Couplers zisetyenziswa kwiisekethe zedijithali ukukhulisa imiqondiso ye-pulse.
(5) Ukusetyenziswa kwisekethe ethe tyaba
I-Linear coupler isetyenziswa kwi-linear circuit, enomgca ophezulu kunye nokusebenza kakuhle kokwahlulwa kombane emhlabeni.
(6) Isicelo kwiminyhadala ekhethekileyo
I-coupler ingasetyenziswa nakwi-high voltage control, ithathe indawo ye-transformer, ithathe indawo ye-contact relay kunye ne-A / D circuit.

Izalathisi zobugcisa
1. Idigri yokudibanisa: umahluko othe ngqo phakathi kwamandla okukhupha avela kwizibuko lokudibanisa kunye namandla esignali yokufaka xa amandla esignali edlula kwi-coupler.
2. Idigri yokwahlulwa: ibhekisa ekuhlukanisweni phakathi kwezibuko zokukhupha kunye nezibuko zokudibanisa; Ngokubanzi, olu luhlu lusetyenziswa kuphela ukulinganisa i-microstrip coupler. Kwaye luyahluka ngokwedigri yokudibanisa: umzekelo, i-5-10db yi-18 ~ 23dB, i-15dB yi-20 ~ 25dB, kwaye i-20dB (kubandakanya ngasentla) yi-25 ~ 30dB; idigri yokwahlulwa kwe-cavity coupler ilungile kakhulu, ngoko ke akukho mfuneko yale dilesi.
3. I-Directivity: ibhekisa kwixabiso lokuhlukaniswa phakathi kwe-output port kunye ne-coupling port ngaphandle kwexabiso le-coupling degree. Ekubeni i-directivity ye-microstrip incipha kancinci kancinci ngokunyuka kwe-coupling degree, ngokusisiseko akukho directivity engaphezulu kwe-30dB, ngoko ke akukho mfuneko ye-index enjalo kwi-microstrip coupler. I-directivity ye-cavity coupler ngokubanzi yi-17 ~ 19dB kwi-1700 ~ 2200MHz, 824 ～ 960MHz: 18 ～ 22dB.
4. Indlela yokubala: isikhokelo = ukwahlulwa - ukudibanisa.
5. Ukulahleka kokufakwa: kubhekisa kwixabiso elifunyenwe ngokuthabatha ixabiso lokulahleka kokusasazwa kumandla esignali ancitshisiweyo kumandla esignali ngokusebenzisa i-coupler ukuya kwisiphumo. Ngokubanzi, ukulahleka kokufakwa kwe-microstrip coupler kuyahluka ngokwezinga lokudibanisa. Ngokubanzi, yi-0.35 ~ 0.5dB ngaphantsi kwe-10dB kunye ne-0.2 ~ 0.5dB ngaphezulu kwe-10dB.
6. Umlinganiselo wamaza okuma okufakwayo/okuphumayo: ubhekisa ekufanisweni kwamazibuko okufakwayo/okuphumayo, kwaye iimfuno zezibuko ngalinye ngokubanzi ziyi-1.2 ~ 1.4;
7. Ukunyamezelana kwamandla: kubhekisa kukunyamezelana kwamandla okusebenza okuphezulu okunokudlula kule coupler ixesha elide (ngaphandle komonakalo). Ngokubanzi, amandla aphakathi e-microstrip coupler yi-30 ~ 70W, kwaye lawo e-cavity yi-100 ~ 200W.
8. Uluhlu lweefrikhwensi: ngokubanzi, ifrikhwensi eqhelekileyo yi-800 ~ 2200MHz. Enyanisweni, ibhendi yefrikhwensi efunekayo yi-824-960MHz kunye ne-1710 ~ 2200MHz. Ibhendi yefrikhwensi ephakathi ayifumaneki.
9. Kwibhendi ethi Flatness: ibhekisa kumahluko phakathi kweqondo eliphezulu nelincinci lokudibanisa kwibhendi yonke yefrikhwensi ekhoyo. I-Microstrip ngokubanzi yi-0.5 ~ 0.2db. Umqolo: ekubeni iqondo lokudibanisa lijika, akukho mfuneko injalo.

Singakwazi nokwenza ngokwezifiso iinxalenye ze-rf passive ngokweemfuno zakho. Ungangena kwiphepha lokwenza ngokwezifiso ukuze unikeze iinkcukacha ozifunayo.
