Main Functions
Precision Band Isolation: Passes GSM900 uplink (890-915MHz) and downlink (935-960MHz) signals with optimized low loss (as low as ≤0.35dB), while blocking interference from adjacent public safety/industrial bands.
Critical Interference Suppression: Provides ≥50dB rejection in 869-884MHz (TETRA/CDMA) and ≥25dB in 930-934MHz (LTE Band 8 guard band), ensuring clean GSM network operation.
Control Signal Integration: Features DC/AISG bypass for remote antenna unit management and 5kA lightning protection for outdoor resilience.
Typical Application Scenarios
GSM Network Modernization: Deployed in 2G macro sites to prevent interference from nearby 800MHz LTE or 900MHz utilities, extending legacy network lifespan.
Industrial Campus Coverage: Filters noise in mining/port communications using GSM900, with IP67-rated durability against dust/moisture (0°C to +65°C).
Rural Base Stations: Secures GSM signals in remote towers via pole-mounting (Φ35-135mm clamps included), handling 100W power for wide-area coverage.
Technical Features
Optimized RF Performance: Delivers ultra-low insertion loss (≤0.35dB@947.5-960MHz) with frequency-specific optimization and low PIM (-155dBc).
High-Power Resilience: Supports 100W continuous power (80W@936-937MHz) via 4.3-10 Female connectors, with robust aluminum housing (348x292x136mm, 15kg).
Industrial Protection: Features IP67 environmental sealing, lightning surge protection (8/20µs pulse), and ROHS compliance for harsh outdoor deployments
