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.
Chogawa mphamvu
Chogawa mphamvundi chipangizo chomwe chimagawa chizindikiro chimodzi cholowera m'magawo awiri kapena angapo ofanana amagetsi
kapangidwe kake kagawidwa m'magulu awiri:
（1） Makhalidwe akuluakulu a chogawa mphamvu chosagwira ntchito ndi awa: kugwira ntchito kokhazikika, kapangidwe kosavuta komanso kopanda phokoso; Vuto lake lalikulu ndilakuti kutayika kwa mwayi kumakhala kwakukulu kwambiri.
（2） Chogawa mphamvu chogwira ntchito chimapangidwa ndi amplifier. Makhalidwe ake akuluakulu ndi awa: kupeza mphamvu ndi kudzipatula kwakukulu. Zoyipa zake zazikulu ndi phokoso, kapangidwe kovuta komanso kukhazikika koyipa kwa ntchito. Cholumikizira chotulutsa mphamvu chili ndi ma power point awiri, ma power point atatu, ma power point anayi, ma power point asanu ndi limodzi, ma power point asanu ndi atatu ndi ma power point khumi ndi awiri.
Ndi chipangizo chomwe chimagawa mphamvu imodzi ya chizindikiro cholowera m'njira ziwiri kapena zingapo ndikutulutsa mphamvu zofanana kapena zosafanana. Kenako, imatha kupanga mphamvu zingapo za chizindikiro kukhala chotulutsa chimodzi. Pakadali pano, imathanso kutchedwa chophatikiza. Kupatula kwina kuyenera kutsimikizika pakati pa madoko otulutsa a chogawa mphamvu. Malinga ndi kutulutsa, chogawa mphamvu nthawi zambiri chimagawidwa m'magulu awiri (cholowetsa chimodzi ndi zotulutsa ziwiri), chimodzi mwa zitatu (cholowetsa chimodzi ndi zotulutsa zitatu), ndi zina zotero. Magawo akuluakulu aukadaulo a chogawa mphamvu ndi kutayika kwa mphamvu (kuphatikiza kutayika kwa kulowetsa, kutayika kwa kugawa ndi kutayika kwa kuwunikira), chiŵerengero cha mafunde oyima a doko lililonse, kutayika pakati pa madoko ogawa mphamvu, kulinganiza kwa amplitude, kulinganiza kwa gawo, mphamvu yamagetsi ndi bandwidth, ndi zina zotero.
Zizindikiro zaukadaulo
Ma index aukadaulo a mphamvu yogawa magetsi ndi monga ma frequency range, mphamvu yonyamula katundu, kutayika kwa magawidwe kuchokera ku main circuit kupita ku nthambi, kutayika kwa insertion pakati pa input ndi output, kudzipatula pakati pa ma branch ports, voltage standing wave ratio ya doko lililonse, ndi zina zotero.
1. Ma frequency range: Iyi ndi njira yogwirira ntchito ya ma RF / ma microwave circuits osiyanasiyana. Kapangidwe ka kagawidwe ka magetsi kamagwirizana kwambiri ndi ma frequency ogwirira ntchito. Ma frequency ogwirira ntchito a wogawika ayenera kufotokozedwa kaye asanapangidwe kake.
2. Mphamvu yonyamula: mu chogawa/chopangira mphamvu champhamvu kwambiri, mphamvu yayikulu yomwe gawo la circuit lingathe kunyamula ndi chizindikiro chapakati, chomwe chimasankha mtundu wa mzere wotumizira womwe ungagwiritsidwe ntchito kukwaniritsa ntchito yopangira. Kawirikawiri, dongosolo la mphamvu yonyamulidwa ndi mzere wotumizira kuyambira yaying'ono mpaka yayikulu ndi mzere wa microstrip, stripline, coaxial line, air stripline ndi air coaxial line. Ndi mzere uti womwe uyenera kusankhidwa malinga ndi ntchito yopangira.
3. Kutayika kwa magawidwe: kutayika kwa magawidwe kuchokera ku dera lalikulu kupita ku dera la nthambi kumakhudzana kwambiri ndi chiŵerengero cha magawidwe a mphamvu cha wogawa mphamvu. Mwachitsanzo, kutayika kwa magawidwe a magawidwe awiri ofanana a mphamvu ndi 3dB ndipo kwa magawidwe anayi ofanana a mphamvu ndi 6dB.
4. Kutayika kwa kulowetsa: kutayika kwa kulowetsa pakati pa kulowetsa ndi kutulutsa kumachitika chifukwa cha dielectric yosakwanira kapena kondakitala ya mzere wotumizira (monga mzere wa microstrip) ndikuganizira chiŵerengero cha mafunde oyima kumapeto kwa kulowetsa.
5. Digiri yodzipatula: digiri yodzipatula pakati pa madoko a nthambi ndi chizindikiro china chofunikira cha wogawa mphamvu. Ngati mphamvu yolowera kuchokera ku doko lililonse la nthambi ikhoza kutuluka kuchokera ku doko lalikulu lokha ndipo siyenera kutuluka kuchokera ku nthambi zina, imafunika kudzipatula kokwanira pakati pa nthambi.
6. VSWR: VSWR ya doko lililonse ikakhala yaying'ono, zimakhala bwino.

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