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.
Chogawa mphamvu
Chogawa mphamvundi chipangizo chomwe chimagawaniza chizindikiro chimodzi kukhala mphamvu ziwiri kapena zingapo zofanana
mwadongosolo agawidwa m'magulu awiri:
(1) Makhalidwe akuluakulu a zogawira mphamvu zopanda mphamvu ndi: ntchito yokhazikika, kapangidwe kosavuta komanso kopanda phokoso; Choyipa chake chachikulu ndikuti kutaya mwayi ndikwambiri.
(2) Chigawo champhamvu chogwira ntchito chimapangidwa ndi amplifier. Makhalidwe ake akuluakulu ndi: kupindula ndi kudzipatula kwakukulu. Zoyipa zake zazikulu ndi phokoso, kapangidwe kake kovutirapo komanso kusakhazikika bwino pantchito. Doko lotulutsa la chogawa mphamvu lili ndi magawo awiri amagetsi, malo atatu opangira mphamvu, malo opangira magetsi anayi, malo asanu ndi limodzi, malo asanu ndi atatu amagetsi ndi magawo khumi ndi awiri.
Ndi chipangizo chomwe chimagawanitsa mphamvu ya siginecha imodzi m'njira ziwiri kapena zingapo ndikutulutsa mphamvu zofanana kapena zosafanana. Kenako, imatha kuphatikizira mphamvu zambiri zama siginecha kukhala imodzi. Panthawiyi, imathanso kutchedwa "comminer". Mulingo wina wodzipatula udzatsimikizirika pakati pa madoko otuluka a chogawa mphamvu. Malinga ndi linanena bungwe, mphamvu divider zambiri anawagawa mu awiri (athandizira mmodzi ndi zotuluka ziwiri), mmodzi mwa atatu (athandizira mmodzi ndi zotuluka atatu), etc. waukulu magawo luso la ogawa mphamvu ndi kutayika mphamvu (kuphatikizapo imfa kuika, kugawa imfa ndi kusinkhasinkha imfa), voteji kuyimirira yoweyula chiŵerengero cha doko lililonse, kudzipatula pakati pa madoko kugawa mphamvu, matalikidwe bwino, gawo bwino, mphamvu ndi bandiwifi, etc.
Zizindikiro zaukadaulo
Zolozera zaukadaulo zamagawo amagetsi zimaphatikizapo kuchuluka kwa ma frequency, mphamvu zonyamula, kutayika kwa magawo kuchokera kudera lalikulu kupita kunthambi, kutayika koyika pakati pa zolowetsa ndi zotuluka, kudzipatula pakati pa madoko a nthambi, chiwongolero cha mafunde amagetsi padoko lililonse, ndi zina zambiri.
1. Kuchuluka kwa ma frequency: Awa ndi malo ogwirira ntchito osiyanasiyana a RF / microwave. Mapangidwe apangidwe a wogawira mphamvu amagwirizana kwambiri ndi maulendo ogwira ntchito. Kuchuluka kwa ntchito kwa wogawayo kuyenera kufotokozedwa musanayambe ndondomeko yotsatirayi
2. Mphamvu zokhala ndi mphamvu: mu wogawira / synthesizer wapamwamba kwambiri, mphamvu yaikulu yomwe gawo la dera lingathe kunyamula ndilo ndondomeko yapakati, yomwe imatsimikizira kuti ndi njira yanji yotumizira yomwe ingagwiritsidwe ntchito kukwaniritsa ntchito yokonza. Nthawi zambiri, dongosolo la mphamvu zoyendetsedwa ndi chingwe chopatsira kuchokera chaching'ono kupita chachikulu ndi chingwe cha microstrip, stripline, coaxial line, air stripline ndi air coaxial line. Mzere uti uyenera kusankhidwa molingana ndi ntchito yokonza.
3. Kutayika kwagawidwe: kutayika kwagawidwe kuchokera ku dera lalikulu kupita ku dera la nthambi makamaka kumagwirizana ndi chiŵerengero cha kugawa mphamvu kwa wogawa mphamvu. Mwachitsanzo, kutayika kwa magawo awiri ogawa mphamvu ndi 3dB ndipo kwa magawo anayi ofanana ndi 6dB.
4. Kutayika kwa kulowetsa: kutayika kwa kuika pakati pa kulowetsa ndi kutulutsa kumayambitsidwa ndi dielectric yopanda ungwiro kapena kondakitala wa mzere wotumizira (monga microstrip line) ndikuganizira chiwerengero cha mafunde oima pamapeto olowera.
5. Digiri yodzipatula: digiri yodzipatula pakati pa madoko a nthambi ndi index ina yofunika kwambiri yogawa mphamvu. Ngati mphamvu yolowera kuchokera ku doko lililonse la nthambi imatha kutulutsa kuchokera ku doko lalikulu ndipo sayenera kutulutsa kuchokera kunthambi zina, pamafunika kudzipatula kokwanira pakati pa nthambi.
6. VSWR: VSWR yaying'ono ya doko lililonse, ndiyabwinoko.

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