Ukadaulo wa Microwave wa Sichuan Keenlion——chogawa mphamvu
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 mphamvu imodzi ya chizindikiro cholowera m'njira ziwiri kapena zingapo ndipo chimatulutsa mphamvu yofanana kapena yosafanana. Kenako, chimatha kupanga mphamvu zingapo za chizindikiro kukhala chotulutsa chimodzi. Pakadali pano, chimathanso kutchedwa chophatikiza.

Pakati pa ma doko otulutsa a power divider payenera kukhala kugawika kwinakwake pakati pa ma output ports a power divider. Power distributor imatchedwanso over-current distributor, yomwe imagawidwa m'magulu awiri: active ndi passive. Imatha kugawa chizindikiro chimodzi mofanana m'ma output angapo. Nthawi zambiri, sub channel iliyonse imakhala ndi dB attenuation zingapo. Kuchepa kwa ma distributor osiyanasiyana kumasiyananso chifukwa cha ma frequency osiyanasiyana a signal. Pofuna kubweza kuchepa kwa ma attenuation, passive power divider imapangidwa pambuyo powonjezera amplifier.

Chiyambi cha ntchito

Ntchito ya wogawa magetsi ndikugawa mofanana satelayiti ngati chizindikiro chikulowa kuchokera ku njira imodzi kupita ku njira zingapo zotulutsira, nthawi zambiri kuphatikiza kugawa magetsi awiri, kugawa magetsi anayi, kugawa magetsi asanu ndi limodzi ndi zina zotero. Kugwiritsa ntchito ndi magwiridwe antchito a zida zitatu zomwe zili pamwambapa ndizosiyana kwambiri, koma nthawi zambiri zimakhala zosavuta kusokoneza mayina omwe amagwiritsidwa ntchito tsiku ndi tsiku, zomwe zimapangitsa anthu kusokonezeka akamagwiritsa ntchito. Ma satellite receiver angapo mu satellite TV receiver system amagawana antenna imodzi, ma antenna angapo amagawana satellite receiver imodzi, ndipo ma satellite receiver oposa awiri ndi ma antenna oposa awiri amagawana. Kuphatikiza pa zingwe, kulumikizana pakati pawo kumachitika makamaka ndi kuphatikiza.

Kupanga mapulogalamu a ma switcher. Chogawa magetsi chimagwiritsidwa ntchito kulumikiza ma satellite receiver angapo. Ngati ma antenna akufunika kulumikizidwa ku ma satellite receiver angapo, chogawa magetsi chiyenera kugwiritsidwa ntchito. Sankhani chogawa magetsi malinga ndi chiwerengero cha ma receiver omwe alumikizidwa. Ngati ma receiver awiri alumikizidwa, chogawa magetsi awiri chimagwiritsidwa ntchito. Lumikizani ma receiver anayi ndikugwiritsa ntchito ma power receiver anayi.

Zizindikiro zaukadaulo

Ma index aukadaulo a magetsi ogawa magetsi amaphatikizapo kuchuluka kwa ma frequency, mphamvu yonyamula ma bearing, kutayika kwa ma distribution 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 kapangidwe ka magetsi ogawa magetsi kamagwirizana kwambiri ndi ma frequency ogwirira ntchito. Ma frequency ogwirira ntchito a makina ogawa magetsi ayenera kufotokozedwa kaye asanapangidwe kake.

2. Kupirira mphamvu. Mu chogawa/synthesizer champhamvu kwambiri, mphamvu yayikulu yomwe zigawo za circuit zimatha kunyamula ndi core index, yomwe imasankha mtundu wa mzere wotumizira womwe ungagwiritsidwe ntchito kukwaniritsa ntchito yopangira. Kawirikawiri, dongosolo la mphamvu lomwe limayendetsedwa ndi mzere wotumizira kuyambira yaying'ono mpaka yayikulu ndi microstrip line, stripline, coaxial line, air stripline ndi air coaxial line. Ndi mzere uti womwe uyenera kusankhidwa malinga ndi ntchito yopangira.

3. Gawani zotayika. Kutayika kwa kugawa kuchokera ku dera lalikulu kupita ku dera la nthambi kumagwirizana kwambiri ndi chiŵerengero cha kugawa kwa mphamvu cha wogawa mphamvu. Mwachitsanzo, kutayika kwa kugawa kwa magawo awiri ofanana a mphamvu ndi 3dB ndipo kwa magawo anayi ofanana a mphamvu ndi 6dB.

4. Kutayika kwa kulowetsa. Kutayika kwa kulowetsa pakati pa kulowetsa ndi kutulutsa kumachitika chifukwa cha njira yosakwanira kapena kondakitala ya chingwe chotumizira (monga mzere wa microstrip), poganizira kutayika komwe kumachitika chifukwa cha chiŵerengero cha mafunde oyima pa cholowetsa.

5. Kupatula. Kupatula 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. Chiŵerengero cha mafunde oima. Kaya VSWR ya doko lililonse ndi yaying'ono, zimakhala bwino.

Thechogawa mphamvuMalinga ndi kapangidwe kake, zinthuzo zitha kugawidwa 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.

Dzina lonse la chogawa mphamvu ndi chogawa mphamvu. Ndi chipangizo chomwe chimagawa mphamvu imodzi ya chizindikiro cholowera m'njira ziwiri kapena zingapo ndipo chimatulutsa mphamvu yofanana kapena yosagwirizana. Kenako, chimatha kupanga mphamvu zingapo za chizindikiro kukhala chotulutsa chimodzi. Pakadali pano, chimathanso 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 mu zitatu (cholowetsa chimodzi ndi zotulutsa zitatu), ndi zina zotero. Magawo akuluakulu aukadaulo a chogawa mphamvu ndi monga 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 m'lifupi mwa band ya pafupipafupi.

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