Sichuan Keenlion Microwave Technology Yakhazikitsidwa mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ndi omwe amapanga zida za Passive Mircrowave ku Sichuan Chengdu, China.
Timapereka zigawo za mirrowave zogwira ntchito kwambiri ndi ntchito zina zofananira ndi ntchito za microwave kunyumba ndi kunja. Zogulitsazo ndizotsika mtengo, kuphatikiza zogawa mphamvu zosiyanasiyana, zolumikizira zowongolera, zosefera, zophatikizira, ma duplexer, zida zongopanga zokha, zodzipatula komanso zozungulira. Zogulitsa zathu zidapangidwa mwapadera kuti zizitha kusiyanasiyana komanso kutentha kwambiri. Zofotokozera zitha kupangidwa molingana ndi zomwe makasitomala amafuna ndipo zimagwira ntchito pamagulu onse odziwika komanso otchuka omwe ali ndi ma bandwidth osiyanasiyana kuchokera ku DC mpaka 50GHz.
coupler
Gawo logawa mphamvu pakugawa chizindikiro cha RF munjira ziwiri molingana ndikuzitulutsa ku dongosolo la antenna feeder.

Ntchito zazikulu
(1) Kugwiritsa ntchito logic circuit
The coupler imatha kupanga mabwalo osiyanasiyana omveka. Chifukwa chotsutsana ndi kusokoneza ndi kudzipatula ntchito ya coupler ndi yabwino kuposa ya transistor, logic dera lopangidwa ndi izo ndi lodalirika kwambiri.
Magawo ogwiritsira ntchito ndi zochitika za coupler
(2) Kugwiritsa ntchito ngati chosinthira cholimba
M'magawo osinthira, nthawi zambiri pamafunika kuti pakhale kudzipatula kwamagetsi kwabwino pakati pa chigawo chowongolera ndi chosinthira, chomwe chimakhala chovuta pakusintha kwamagetsi, koma ndikosavuta kuzindikira ndi coupler.
(3) Kugwiritsa ntchito poyambira
Pamene coupler ntchito mu bistable linanena bungwe dera, vuto kudzipatula pakati linanena bungwe ndi katundu akhoza bwino kuthetsedwa chifukwa LED akhoza olumikizidwa mu mndandanda mu emitter dera machubu awiri motero.
(4) Kugwiritsa ntchito pulse amplification circuit
Maanja amagwiritsidwa ntchito mumayendedwe a digito kuti akweze ma siginecha akugunda.
(5) Kugwiritsa ntchito mzere wozungulira
Linear coupler imagwiritsidwa ntchito mu mzere wozungulira, womwe uli ndi mzere wapamwamba komanso ntchito yabwino kwambiri yodzipatula yamagetsi.
(6) Kugwiritsa ntchito pazochitika zapadera
The coupler itha kugwiritsidwanso ntchito pakuwongolera ma voliyumu apamwamba, m'malo mwa thiransifoma, m'malo mwa ma relay olumikizana ndi dera la A / D.

Zizindikiro zaukadaulo
1. Digiri yolumikizirana: kusiyanitsa kwachindunji pakati pa mphamvu yotulutsa kuchokera ku doko lolumikizirana ndi mphamvu yolumikizira pomwe mphamvu yazizindikiro ikudutsa pa coupler.
2. Digiri yodzipatula: imatanthawuza kudzipatula pakati pa doko lotulutsa ndi doko lolumikizira; Nthawi zambiri, index iyi imagwiritsidwa ntchito kuyeza microstrip coupler. Ndipo zimasiyanasiyana malinga ndi digiri yolumikizira: mwachitsanzo, 5-10db ndi 18 ~ 23dB, 15dB ndi 20 ~ 25dB, ndi 20dB (kuphatikiza pamwambapa) ndi 25 ~ 30dB; Digiri yodzipatula ya coupler ya cavity ndi yabwino kwambiri, kotero palibe chofunikira pa index iyi.
3. Kuwongolera: kumatanthauza kufunika kwa kudzipatula pakati pa doko lotulutsa ndi doko lolumikizira kuchotsera mtengo wa digiri yolumikizira. Popeza kuwongolera kwa microstrip kumachepa pang'onopang'ono ndikuwonjezeka kwa digiri yolumikizira, kwenikweni palibe kuwongolera pamwamba pa 30dB, kotero palibe cholozera chofunikira cha microstrip coupler. Kuwongolera kwa coupler paboti nthawi zambiri kumakhala 17 ~ 19dB pa 1700 ~ 2200MHz, 824 ~ 960MHz: 18 ~ 22dB.
4. Njira yowerengera: directivity = kudzipatula - kugwirizana.
5. Kutayika kolowetsa: kumatanthauza mtengo wopezedwa mwa kuchotsa mtengo wa kugawa kutayika kuchokera ku mphamvu yochepetsera chizindikiro kuchokera ku mphamvu ya chizindikiro kupyolera mu coupler kupita ku zotsatira. Nthawi zambiri, kutayika kwa kuyika kwa microstrip coupler kumasiyanasiyana malinga ndi digirii yolumikizira. Nthawi zambiri, ndi 0.35 ~ 0.5dB yochepera 10dB ndi 0.2 ~ 0.5dB kuposa 10dB.
6. Chiŵerengero cha mafunde olowetsa / chotulukapo: chimatanthawuza kufanana kwa madoko olowetsa / zotuluka, ndipo zofunikira pa doko lililonse nthawi zambiri zimakhala 1.2 ~ 1.4;
7. Kulekerera kwamphamvu: kumatanthauza kulolerana kwamphamvu kwamphamvu komwe kumatha kudutsa mu coupler iyi kwa nthawi yayitali (popanda kuwonongeka). Nthawi zambiri, mphamvu ya microstrip coupler ndi 30 ~ 70W, ndipo yapakati ndi 100 ~ 200W.
8. Mafupipafupi osiyanasiyana: zambiri, pafupipafupi mwadzina ndi 800 ~ 2200MHz. M'malo mwake, gulu lofunikira pafupipafupi ndi 824-960MHz kuphatikiza 1710 ~ 2200MHz. Gulu lapakati lapakati silikupezeka.
9. Mu gulu Flatness: amatanthauza kusiyana pazipita ndi osachepera lumikiza digiri mu lonse kupezeka pafupipafupi gulu. Microstrip nthawi zambiri imakhala 0.5 ~ 0.2db. Cavity: popeza digiri yolumikizana ndi yopindika, palibe chofunikira chotero.

Titha kusinthanso magawo a rf passive malinga ndi zomwe mukufuna. Mutha kulowa patsamba losintha kuti mupereke zomwe mukufuna.
