Sichuan Keenlion Microwave Technology——chogawa mphamvu
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 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. Wogawa mphamvu amatchedwanso over-current distributor, yomwe imagawidwa kukhala yogwira ntchito komanso yopanda pake. Ikhoza kugawa mofanana chizindikiro chimodzi muzotulutsa zingapo. Nthawi zambiri, sub channel iliyonse imakhala ndi ma dB angapo. Kutsika kwa ogawa osiyanasiyana kumasiyananso chifukwa cha ma frequency osiyanasiyana. Pofuna kubweza chiwongoladzanja, chogawika champhamvu chimapangidwa pambuyo powonjezera amplifier.

Chiyambi cha ntchito

Ntchito ya wogawira mphamvu ndikugawanitsa satellite ngati kulowetsa kwa siginecha kuchokera kunjira imodzi kupita kunjira zingapo zotulutsa, nthawi zambiri kuphatikiza magawo awiri amagetsi, magawo anayi amagetsi, magawo asanu ndi limodzi ndi zina zotero. Kugwiritsiridwa ntchito ndi machitidwe a zipangizo zitatu zomwe zili pamwambazi ndizosiyana kwambiri, koma nthawi zambiri zimakhala zosavuta kusokoneza mayina omwe amagwiritsidwa ntchito tsiku ndi tsiku, zomwe zimapangitsa kuti anthu asokonezeke pogwiritsira ntchito. Olandila ma satelayiti angapo mu makina olandirira TV satana amagawana mlongoti umodzi, tinyanga zingapo zimagawana cholandila cha satellite imodzi, komanso zolandila satelayiti zopitilira ziwiri komanso tinyanga zopitilira ziwiri. Kuphatikiza pa zingwe, kulumikizana pakati pawo kumazindikiridwa makamaka ndi kuphatikiza

kupanga ma switchers. Wogawa mphamvu amagwiritsidwa ntchito kulumikiza ma satellite angapo olandila. Ngati seti ya tinyanga ikufunika kulumikizidwa ndi zolandila zambiri za satana, wogawa mphamvu ayenera kugwiritsidwa ntchito. Sankhani wogawa mphamvu molingana ndi kuchuluka kwa olandila olumikizidwa. Ngati olandila awiri alumikizidwa, wogawa mphamvu ziwiri amagwiritsidwa ntchito. Lumikizani olandila anayi ndikugwiritsa ntchito ogawa magetsi anayi.

Zizindikiro zaukadaulo

Ma index aukadaulo a ogawa mphamvu amaphatikiza kuchuluka kwa ma frequency, mphamvu zonyamula, kutayika kwa magawo kuchokera kudera lalikulu kupita kunthambi, kutayika koyika pakati pa zolowetsa ndi zotulutsa, kudzipatula pakati pa madoko a nthambi, chiwongolero cha mafunde amagetsi pa doko lililonse, ndi zina zambiri.

1. Nthawi zambiri. Izi ndizomwe zimagwira ntchito pamabwalo 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. Kupirira mphamvu. Mu ogawa / synthesizer amphamvu kwambiri, mphamvu yayikulu yomwe zigawo zozungulira zimatha kunyamula ndi index yayikulu, yomwe imatsimikizira mtundu wamtundu wotumizira womwe ungagwiritsidwe ntchito kukwaniritsa ntchitoyi. 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. Perekani zotayika. Kutayika kogawa kuchokera kudera lalikulu kupita kudera lanthambi kumakhudzana kwenikweni ndi chiŵerengero cha kugawa kwa mphamvu kwa wogawa mphamvu. Mwachitsanzo, kutayika kwa magawo awiri ogawa mphamvu ndi 3dB ndipo kwa magawo anayi ofanana ndi 6dB.

4. Kuyika kutaya. Kutayika koyikapo pakati pa kulowetsa ndi kutulutsa kumayambitsidwa ndi sing'anga yopanda ungwiro kapena kokondetsa wa chingwe chotumizira (monga microstrip line), poganizira kutayika komwe kumadza chifukwa cha chiŵerengero cha mafunde oyimilira pa kulowetsa.

5. Kudzipatula. Kudzipatula 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.Standing wave ratio. Zing'onozing'ono za VSWR za doko lililonse, zimakhala bwino.

Thechogawa mphamvuatha kugawidwa m'magulu awiri malinga ndi kapangidwe:

(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.

Dzina lonse la chogawa mphamvu ndi chogawa mphamvu. 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, chogawa mphamvu zambiri anawagawa mu awiri (athandizira mmodzi ndi zotuluka awiri), mmodzi kukhala atatu (athandizira mmodzi ndi zotuluka atatu), etc. waukulu magawo luso la ogawa mphamvu monga kutayika mphamvu (kuphatikizapo imfa kuika, kugawa imfa ndi kusinkhasinkha imfa), voteji kuyimirira mafunde chiŵerengero cha doko lililonse, kudzipatula pakati pa madoko kugawa mphamvu, matalikidwe bwino, gawo bwino, mphamvu mphamvu ndi pafupipafupi gulu m'lifupi.

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