Ukadaulo wa Microwave wa Sichuan Keenlion womwe unayamba mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ndiye wopanga wamkulu wa zida za Passive Mircrowave ku Sichuan Chengdu, China.
Timapereka zida za mirrowave zogwira ntchito bwino komanso ntchito zina zokhudzana ndi ntchito za microwave kunyumba ndi kunja. Zogulitsazi ndizotsika mtengo, kuphatikizapo zida zosiyanasiyana zogawa mphamvu, zolumikizira zolunjika, zosefera, zophatikiza, zoduplex, zida zosinthira zamagetsi, zosungunulira ndi zozungulira. Zogulitsa zathu zimapangidwa mwapadera kuti zigwirizane ndi malo osiyanasiyana otentha kwambiri. Mafotokozedwe amatha kupangidwa malinga ndi zosowa za makasitomala ndipo amagwiritsidwa ntchito pa ma frequency band onse omwe ali ndi ma bandwidth osiyanasiyana kuyambira DC mpaka 50GHz.
cholumikizira
Gawo logawa mphamvu logawa chizindikiro cha RF m'njira ziwiri molingana ndikuchitulutsa ku dongosolo lodyetsa ma antenna

Ntchito zazikulu
(1) Kugwiritsa ntchito mu dongosolo la logic
Cholumikiziracho chimatha kupanga ma logic circuits osiyanasiyana. Chifukwa chakuti cholumikiziracho sichimasokoneza komanso chimatha kusiyanitsa bwino kuposa cha transistor, logic circuit yomwe imapangidwa nayo ndi yodalirika kwambiri.
Magawo ogwiritsira ntchito ndi zochitika za coupler
(2) Kugwiritsa ntchito ngati chosinthira champhamvu
Mu circuit yosinthira, nthawi zambiri pamafunika kukhala ndi malo abwino olekanitsira magetsi pakati pa circuit yowongolera ndi switch, zomwe zimakhala zovuta pa switch yamagetsi yonse, koma n'zosavuta kuzizindikira ndi cholumikizira.
(3) Kugwiritsa ntchito mu choyambitsa choyambira
Pamene cholumikizira chikugwiritsidwa ntchito mu bistable output circuit, vuto la kudzipatula pakati pa output ndi load lingathe kuthetsedwa bwino chifukwa LED ikhoza kulumikizidwa motsatizana mu emitter circuit ya machubu awiri motsatana.
(4) Kugwiritsa ntchito mu dera lokulitsa ma pulse
Zolumikizira zimagwiritsidwa ntchito m'mabwalo a digito kuti ziwonjezere zizindikiro za pulse.
(5) Kugwiritsa ntchito mu mzere wolunjika
Cholumikizira cha mzere chimagwiritsidwa ntchito mu mzere, chomwe chili ndi mzere wapamwamba komanso magwiridwe antchito abwino kwambiri olekanitsa magetsi.
(6) Kufunsira pazochitika zapadera
Cholumikizirachi chingagwiritsidwenso ntchito powongolera magetsi ambiri, kusintha transformer, kusintha ma contact relay ndi A / D circuit.

Zizindikiro zaukadaulo
1. Mlingo wolumikizira: kusiyana kwachindunji pakati pa mphamvu yotulutsa kuchokera ku doko lolumikizira ndi mphamvu ya chizindikiro cholowera pamene mphamvu ya chizindikiro imadutsa mu cholumikizira.
2. Digiri yodzipatula: imatanthauza kudzipatula pakati pa doko lotulutsa ndi doko lolumikizira; Nthawi zambiri, indekisi iyi imagwiritsidwa ntchito poyesa cholumikizira cha microstrip. Ndipo imasiyana malinga ndi digiri yolumikizira: mwachitsanzo, 5-10db ndi 18 ~ 23dB, 15dB ndi 20 ~ 25dB, ndipo 20dB (kuphatikiza pamwambapa) ndi 25 ~ 30dB; digiri yodzipatula ya cholumikizira cha cavity ndi yabwino kwambiri, kotero palibe chifukwa chofunira indekisi iyi.
3. Kuwongolera: kumatanthauza mtengo wa kudzipatula pakati pa doko lotulutsa ndi doko lolumikizira kupatula mtengo wa digiri yolumikizira. Popeza kuwongolera kwa microstrip kumachepa pang'onopang'ono ndi kuwonjezeka kwa digiri yolumikizira, kwenikweni palibe kuwongolera kopitilira 30dB, kotero palibe chofunikira cha index cha cholumikizira cha microstrip. Kuwongolera kwa cholumikizira cha cavity nthawi zambiri kumakhala 17 ~ 19dB pa 1700 ~ 2200MHz, 824 ～ 960MHz: 18 ～ 22dB.
4. Njira yowerengera: chitsogozo = kudzipatula - kuphatikiza.
5. Kutayika kwa kuyika: kumatanthauza mtengo womwe umapezeka pochotsa mtengo wa kutayika kwa kugawa kuchokera ku mphamvu yochepetsedwa ya chizindikiro kuchokera ku mphamvu ya chizindikiro kudzera pa cholumikizira kupita ku chotulutsa. Kawirikawiri, kutayika kwa cholumikizira cha microstrip kumasiyana malinga ndi digiri yolumikizira. Kawirikawiri, ndi 0.35 ~ 0.5dB pa zosakwana 10dB ndi 0.2 ~ 0.5dB pa zoposa 10dB.
6. Chiŵerengero cha mafunde oyima olowera/otuluka: chimatanthauza kufanana kwa madoko olowera/otuluka, ndipo zofunikira pa doko lililonse nthawi zambiri zimakhala 1.2 ~ 1.4;
7. Kulekerera mphamvu: kumatanthauza kulekerera mphamvu yogwira ntchito kwambiri komwe kungadutse mu cholumikizira ichi kwa nthawi yayitali (popanda kuwonongeka). Kawirikawiri, mphamvu yapakati ya cholumikizira cha microstrip ndi 30 ~ 70W, ndipo ya cavity ndi 100 ~ 200W.
8. Ma frequency osiyanasiyana: nthawi zambiri, ma frequency odziwika ndi 800 ~ 2200MHz. Ndipotu, frequency yofunikira ndi 824-960MHz kuphatikiza 1710 ~ 2200MHz. Frequency band yapakati siyikupezeka.
9. Mu gulu la Flatness: limatanthauza kusiyana pakati pa digiri yayikulu ndi yocheperako yolumikizira mu gulu lonse la ma frequency lomwe likupezeka. Microstrip nthawi zambiri imakhala 0.5 ~ 0.2db. Mphepete: popeza digiri yolumikizira ndi yokhota, palibe chofunikira chotere.

Tikhozanso kusintha zinthu za rf passive malinga ndi zomwe mukufuna. Mutha kulowa patsamba losinthira kuti mupereke zofunikira zomwe mukufuna.
