PIM Yotsika 418MHz-420MH/428MHz-430MHz UHF Cavity Duplexer Yokhala ndi Cholumikizira cha N

CDU00418M00430MNSF yochokera ku Concept Microwave ndi Low PIM Cavity Duplexer yokhala ndi ma passband ochokera ku 418-420MH pa low band port ndi 428-430MHz pa high band port yokhala ndi PIM3 ≤-155dBc@2*34dBm. Ili ndi insertion loss yochepera 1.5dB komanso integration yoposa 60 dB. Duplexer imatha kugwira mphamvu yokwana 20 W. Imapezeka mu module yomwe imayesa 170mm x135mm x 39mm. Kapangidwe ka RF cavity duplexer kamangidwa ndi zolumikizira za N/SMA zomwe ndi za akazi. Makonzedwe ena, monga passband yosiyana ndi cholumikizira chosiyana amapezeka pansi pa manambala osiyanasiyana a chitsanzo.

PIM Yotsika imayimira "Low passive intermodulation." Imayimira zinthu zophatikizana zomwe zimapangidwa pamene zizindikiro ziwiri kapena zingapo zimadutsa mu chipangizo chopanda mphamvu chokhala ndi zinthu zosagwirizana ndi mzere. Passive intermodulation ndi vuto lalikulu mkati mwa makampani opanga ma cell ndipo n'kovuta kwambiri kuthetsa mavuto. Mu machitidwe olumikizirana ma cell, PIM imatha kuyambitsa kusokoneza ndipo imachepetsa kukhudzidwa kwa wolandila kapena ingalepheretse kulumikizana kwathunthu. Kusokoneza kumeneku kungakhudze selo lomwe linapanga, komanso zolandila zina zapafupi.
