Iindaba

I-Sichuan Keenlion Microwave Technology Yasekwa ngo-2004, iSichuan Keenlion Mircrowave techenology CO., Ltd. ngumenzi okhokelayo wamacandelo ePassive Mircrowave eSichuan Chengdu, eChina.
Sinikezela ngamacandelo e-mirrowave asebenza kakhulu kunye neenkonzo ezinxulumene noko kwizicelo ze-microwave ekhaya naphesheya. Iimveliso azibizi kakhulu, kubandakanya ukwahlula amandla okwahlukeneyo, ii-couplers ezikhokelayo, izihluzi, izihlanganisi, ii-duplexers, iikhomponenti ezenziwe ngokwezifiso, i-isolator kunye neesetyhula. Iimveliso zethu ziyilelwe ngokukodwa iimeko ezahlukeneyo ezingqongileyo kunye namaqondo obushushu. Iinkcukacha zinokuqulunqwa ngokweemfuno zabathengi kwaye zisebenza kuzo zonke iibhendi eziqhelekileyo kunye nezidumileyo ezinamaza ohlukeneyo ukusuka kwi-DC ukuya kwi-50GHz.
coupler
Icandelo losasazo lwamandla lokwahlula isiginali yeRF ibe ngamajelo amabini ngokomlinganiselo kwaye uyikhuphele kwisixokelelwano se-eriyali.

Usetyenziso oluphambili
(1) Ukusetyenziswa kwisekethe yengqiqo
I-coupler inokwenza iisekethe zengqiqo ezahlukeneyo. Ngenxa yokuba i-anti-interference kunye nokusebenza kwe-isolation ye-coupler ingcono kune-transistor, i-logic circuit circuit eyenziwa yiyo inokwethenjelwa ngakumbi.
Amabala esicelo kunye namathuba e coupler
(2) Isicelo njengokutshintsha kwesimo esiqinileyo
Kwisekethe yokutshintsha, kudla ngokufuneka ukuba ube nombane olungileyo wokuzihlukanisa phakathi kwesekethe yokulawula kunye nokutshintsha, okunzima kumatshini oqhelekileyo we-elektroniki, kodwa kulula ukuyiqonda kunye ne-coupler.
(3) Ukusetyenziswa kwisekethe yokuqalisa
Xa i-coupler isetyenziswa kwisekethe yokuphuma kwe-bistable, ingxaki yokwahlula phakathi kwemveliso kunye nomthwalo ingasonjululwa ngokufanelekileyo kuba i-LED inokudityaniswa kuthotho kwisekethe ye-emitter yeetyhubhu ezimbini ngokulandelelanayo.
(4) Ukusetyenziswa kwe-pulse amplification circuit
Amaqabane asetyenziswa kwiisekethe zedijithali ukukhulisa imiqondiso ye-pulse.
(5) Ukusetyenziswa kwisekethe yomgca
I-coupler yomgca isetyenziswa kwisekethe yomgca, enomgca ophezulu kunye nokusebenza okugqwesileyo kokukodwa kombane.
(6) Ukwenziwa kwesicelo ngezihlandlo ezikhethekileyo
I-coupler inokusetyenziswa kulawulo lwamandla ombane aphezulu, ithatha indawo ye-transformer, ithatha indawo yonxibelelwano lonxibelelwano kunye nesekethe ye-A / D.

Iimpawu zobugcisa
1. Idigri yokudibanisa: umehluko othe ngqo phakathi kombane ophumayo kwi-port yokudibanisa kunye ne-input signal power xa umbane wesignali udlula kwi-coupler.
2. Isidanga sokwahlukaniswa: sibhekisa kukwahlulwa phakathi kwezibuko lemveliso kunye nezibuko lokudibanisa; Ngokubanzi, esi salathisi sisetyenziselwa ukulinganisa i-microstrip coupler. Kwaye iyahluka ngokweqondo lokudibanisa: umzekelo, i-5-10db yi-18 ~ 23dB, 15dB yi-20 ~ 25dB, kunye ne-20dB (kubandakanywa ngasentla) yi-25 ~ 30dB; idigri yokwahlukaniswa kwe-cavity coupler ilunge kakhulu, ngoko akukho mfuneko yesi salathiso.
3. I-Directivity: ibhekisa kwixabiso lokwahlula phakathi kwe-port yemveliso kunye ne-coupling port thabatha ixabiso ledigri yokudibanisa. Ukusukela ukuba i-directivity ye-microstrip iyancipha ngokuthe ngcembe ngokunyuka kwedigri yokudibanisa, akukho khokelo lungaphezulu kwe-30dB, ngoko akukho mfuneko yesalathiso esinjalo kwi-coupler ye-microstrip. I-directivity ye-coupler ye-cavity ngokubanzi yi-17 ~ 19dB kwi-1700 ~ 2200MHz, 824 ~ 960MHz: 18 ~ 22dB.
4. Indlela yokubala: ukuqondisa = ukuzihlukanisa - ukudibanisa.
5. Ilahleko yokufaka: ibhekisela kwixabiso elifunyenwe ngokukhupha ixabiso lelahleko yokusabalalisa ukusuka kumandla omqondiso oncitshisiweyo ukusuka kumandla omqondiso ngokusebenzisa i-coupler ukuya kwisiphumo. Ngokubanzi, ilahleko yokufakwa kwe-microstrip coupler iyahluka ngokwenqanaba lokudibanisa. Ngokubanzi, yi-0.35 ~ 0.5dB ngaphantsi kwe-10dB kunye ne-0.2 ~ 0.5dB ngaphezu kwe-10dB.
6. Igalelo / imveliso emileyo umlinganiselo wamaza: ibhekisa ekuthelekiseni igalelo / izibuko imveliso, kunye neemfuno kwizibuko ngalinye jikelele 1.2 ~ 1.4;
7. Ukunyamezela kwamandla: kubhekisela kukunyamezela kwamandla okusebenza okuphezulu okunokuthi kudlule kule coupler ixesha elide (ngaphandle komonakalo). Ngokubanzi, amandla omndilili we-microstrip coupler yi-30 ~ 70W, kwaye loo mgodi yi-100 ~ 200W.
8. Uluhlu lokuphindaphinda: ngokubanzi, i-frequency ye-nominal yi-800 ~ 2200MHz. Ngapha koko, ibhendi yefrikhwensi efunekayo yi-824-960MHz kunye ne-1710 ~ 2200MHz. Ibhendi yefrikhwensi ephakathi ayifumaneki.
9. Kwibhendi yeFlatness: ibhekisa kumahluko phakathi kowona mgangatho uphezulu kunye nobuncinci bedigri yokudibanisa kuyo yonke ibhendi yamaza ekhoyo. I-Microstrip ngokubanzi yi-0.5 ~ 0.2db. I-Cavity: ekubeni idigri yokudibanisa ijika, akukho mfuneko enjalo.

Sisenokwenza ngokwezifiso amalungu e-rf passive ngokweemfuno zakho. Ungangenisa iphepha lokulungiselela ukubonelela ngeenkcukacha ozifunayo.
