Haʻahaʻa PIM 418MHz-420MH/428MHz-430MHz UHF Cavity Duplexer Me N Mea Hoʻohui

ʻO ka CDU00418M00430MNSF mai Concept Microwave he Low PIM Cavity Duplexer me nā passbands mai 418-420MH ma ke awa band haʻahaʻa a me 428-430MHz ma ke awa hui kiʻekiʻe me PIM3 ≤-155dBc@2*34dBm. Loaʻa iā ia kahi poho hoʻokomo ma lalo o 1.5dB a me kahi kaʻawale ʻoi aku ma mua o 60 dB. Hiki i ka duplexer ke mālama i ka 20 W o ka mana. Loaʻa ia i loko o kahi module e ana ana 170mm x135mm x 39mm. Kūkulu ʻia kēia hoʻolālā RF cavity duplexer me nā mea hoʻohui N/SMA he wahine kāne. Loaʻa nā hoʻonohonoho ʻē aʻe, e like me ka passband ʻokoʻa a me nā mea hoʻohui ʻokoʻa ma lalo o nā helu kumu like ʻole.

ʻO ka PIM haʻahaʻa ke kū nei no "Low passive intermodulation." Hōʻike ia i nā huahana intermodulation i hana ʻia i ka hele ʻana o nā hōʻailona ʻelua a ʻoi aku paha ma o kahi mea passive me nā waiwai nonlinear. He pilikia koʻikoʻi ka intermodulation passive i loko o ka ʻoihana kelepona a paʻakikī loa ka hoʻoponopono. Ma nā ʻōnaehana kamaʻilio kelepona, hiki i ka PIM ke hana i ka hoʻopili ʻana a e hōʻemi i ka naʻau o ka mea hoʻokipa a i ʻole ke kaohi ʻana i ke kamaʻilio. Hiki i kēia keakea ke hoʻopilikia i ke kelepona nāna i hana, a me nā mea hoʻokipa ʻē aʻe e pili ana.
