KataloguMu machitidwe amakono a RF,zogawa mphamvundi zinthu zofunika kwambiri kuti zitsimikizire kufalikira bwino kwa ma siginolo ndi kutumiza mauthenga. Lero, tikuyambitsa ntchito yabwino kwambirichogawa mphamvuya band ya 617-4000MHz, yomwe imagwiritsidwa ntchito kwambiri pakulankhulana opanda zingwe, machitidwe a radar, kulumikizana kwa satellite ndi madera ena.
Zinthu zomwe zili mu malonda:
Thechogawa mphamvuIli ndi kutayika kochepa kwa ma insertion (1.0dB yayikulu), kuonetsetsa kuti kutayika kochepa panthawi yotumizira ma signal. Nthawi yomweyo, VSWR yayikulu kumapeto kwa input ndi 1.50, ndipo VSWR yayikulu kumapeto kwa output ndi 1.30, zomwe zimapangitsa kuti ma signal afalitsidwe bwino komanso mokhazikika. Cholakwika chake cha amplitude balance ndi chochepera ±0.3dB, ndipo cholakwika cha phase balance ndi chochepera ±3°, kuonetsetsa kuti ma signal akugwirizana pakati pa ma output ports ambiri ndikukwaniritsa zosowa za ma signal olondola kwambiri.
Pothandizira mphamvu yayikulu yogawa ya 20W ndi mphamvu yophatikizana ya 1W, ndi yoyenera kugwiritsa ntchito pazochitika zosiyanasiyana za mphamvu. Kuphatikiza apo,chogawa mphamvuIli ndi kutentha kwakukulu komwe imagwira ntchito (-40ºC mpaka +80ºC), komwe kumatha kugwira ntchito mokhazikika m'malo osiyanasiyana ovuta.
Utumiki wosintha ndi chitsimikizo:
Timapatsa makasitomala ntchito zosinthira zomwe akufuna, ndipo timatha kusintha kuchuluka kwa ma frequency, mtundu wa mawonekedwe ndi zina malinga ndi zosowa kuti tiwonetsetse kuti zofunikira za mapulogalamu osiyanasiyana zakwaniritsidwa. Zogulitsa zonse zimapereka chitsimikizo cha zaka zitatu kuti zitsimikizire kuti makasitomala amasangalala ndi chitsimikizo cha khalidwe nthawi zonse komanso chithandizo chaukadaulo akamagwiritsa ntchito.
Chogawa mphamvu cha band cha 617-4000MHz ichi ndi chisankho chabwino kwambiri pa ntchito yogawa ma siginolo a RF chifukwa cha kukhazikika kwake komanso magwiridwe antchito abwino kwambiri.
