Otsika PIM 418MHz-420MH/428MHz-430MHz UHF Cavity Duplexer Ndi N cholumikizira

CDU00418M00430MNSF yochokera ku Concept Microwave ndi Low PIM Cavity Duplexer yokhala ndi ma passbands kuchokera ku 418-420MH padoko lotsika la band ndi 428-430MHz padoko lapamwamba la band ndi PIM3 ≤-155dBc@2 * 34dBm. Ili ndi kutayika koyika kosakwana 1.5dB komanso kudzipatula kopitilira 60 dB. Duplexer imatha kugwira mpaka 20 W mphamvu. Imapezeka mu gawo lomwe limayesa 170mm x135mm x 39mm. Mapangidwe a RF cavity duplexer awa amamangidwa ndi zolumikizira za N/SMA zomwe ndi jenda la akazi. Kusintha kwina, monga chiphaso chosiyana ndi cholumikizira chosiyana chilipo pansi pa manambala amitundu yosiyanasiyana.

Low PIM imayimira "Low passive intermodulation." Zimayimira zinthu zomwe zimapangidwira pamene zizindikiro ziwiri kapena kuposerapo zimadutsa pa chipangizo chokhala ndi zinthu zopanda malire. Kusasinthika kwapang'onopang'ono ndi vuto lalikulu m'makampani opanga ma cellular ndipo ndizovuta kwambiri kuthetsa. M'makina olankhulirana ma cell, PIM imatha kuyambitsa kusokoneza ndipo imachepetsa chidwi cha olandila kapena mwina kulepheretsa kulumikizana kwathunthu. Kusokoneza uku kungakhudze selo lomwe linapanga, komanso olandira ena omwe ali pafupi.
