Tsawg pim Band nres lim LSTF-3700/3900-2N
| Leader-mw | Taw qhia rau qis pim Band nres lim LSTF-3700/3900-2N |
LEADER-MW Low PIM Band Nres Lim LSTF - 3700/3900 - 2N yog cov khoom tshwj xeeb RF. Nws yog tsim los thaiv cov zaus hauv 3700 - 3900 MHz band thaum tso cai rau lwm zaus hla nrog kev cuam tshuam tsawg.
Ib qho ntawm nws cov yam ntxwv tseem ceeb yog nws qhov tsis tshua muaj Passive Intermodulation (PIM) qib ntawm 145 dBc. Qhov qis PIM no yog qhov tseem ceeb hauv kev ua haujlwm siab RF vim nws txo qis cov khoom lag luam uas tsis xav tau uas tuaj yeem ua rau muaj teeb meem cuam tshuam thiab cuam tshuam.
Cov lim dej no zoo tagnrho rau cov ntawv thov xws li cov chaw nres tsheb hauv cellular, qhov uas tswj cov teeb liab purity thiab zoo yog qhov tseem ceeb tshaj plaws. Nws tsim kom ntseeg tau tias kev ua haujlwm ruaj khov hauv kev sib tw RF ib puag ncig. LSTF - 3700/3900 - 2N pab cov tswv lag luam kom ua kom zoo dua lawv cov kev ua haujlwm hauv network los ntawm kev lim tawm tsis xav tau ntau zaus thiab txo PIM - cov teeb meem cuam tshuam, yog li txhim kho tag nrho cov txiaj ntsig thiab kev ntseeg siab ntawm kev sib txuas lus.
