I-PIM Ephansi 418MHz-420MH/428MHz-430MHz UHF Cavity Duplexer Nesixhumi esingu-N

I-CDU00418M00430MNSF evela ku-Concept Microwave iyi-Low PIM Cavity Duplexer enama-passbands asuka ku-418-420MH ku-low band port kanye no-428-430MHz ku-high band port ene-PIM3 ≤-155dBc@2*34dBm. Inokulahlekelwa kokufakwa okungaphansi kuka-1.5dB kanye nokuhlukaniswa okungaphezu kuka-60 dB. I-duplexer ingakwazi ukuphatha amandla angafika ku-20 W. Itholakala kumojula ekala u-170mm x135mm x 39mm. Lo mklamo we-RF cavity duplexer wakhiwe ngezixhumi ze-N/SMA eziwubulili besifazane. Okunye ukucushwa, okufana ne-passband ehlukile nesixhumi esihlukile kuyatholakala ngaphansi kwezinombolo zamamodeli ahlukene.

I-PIM ephansi imele “I-Low passive intermodulation.” Imele imikhiqizo yokushintshashintsha ekhiqizwa lapho amasiginali amabili noma ngaphezulu edlula ngomshini wokwenziwa onezinto ezingaqondile. I-intermodulation engenzi lutho yinkinga ebalulekile embonini yamaselula futhi kunzima kakhulu ukuxazulula inkinga. Ezinhlelweni zokuxhumana ngamaseli, i-PIM ingadala ukuphazamiseka futhi izonciphisa ukuzwela komamukeli noma ingase ivimbele ukuxhumana ngokuphelele. Lokhu kuphazamiseka kungathinta iseli elidalile, kanye nabanye abamukeli abaseduze.
