ʻO ka Duplexer Cavity PIM haʻahaʻa 418MHz-420MH/428MHz-430MHz UHF Me ka mea hoʻohui N

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 band kiʻekiʻe me PIM3 ≤-155dBc@2*34dBm. Loaʻa iā ia kahi pohō hoʻokomo ma lalo o 1.5dB a me kahi isolation ma mua o 60 dB. Hiki i ka duplexer ke lawelawe a hiki i ka 20 W o ka mana. Loaʻa ia i loko o kahi module e ana ana i 170mm x135mm x 39mm. Ua kūkulu ʻia kēia hoʻolālā RF cavity duplexer me nā mea hoʻohui N/SMA he wahine. Loaʻa nā hoʻonohonoho ʻē aʻe, e like me nā passband like ʻole a me nā mea hoʻohui like ʻole ma lalo o nā helu kumu hoʻohālike like ʻole.

ʻO Low PIM ke kū nei no "Low passive intermodulation." Hōʻike ia i nā huahana intermodulation i hana ʻia i ka wā e hele ai ʻelua a ʻoi aku paha nā hōʻailona ma o kahi hāmeʻa passive me nā waiwai nonlinear. He pilikia koʻikoʻi ka passive intermodulation i loko o ka ʻoihana kelepona a he mea paʻakikī loa ke hoʻoponopono pilikia. I loko o nā ʻōnaehana kamaʻilio kelepona, hiki i ka PIM ke hana i ka hoʻopilikia a e hōʻemi i ka ʻike o ka mea hoʻokipa a i ʻole e kāohi loa i ke kamaʻilio ʻana. Hiki i kēia hoʻopilikia ke hoʻopilikia i ke kelepona nāna i hana, a me nā mea hoʻokipa kokoke ʻē aʻe.
