Main Functions
Precise Band Selection: Passes critical RF signals in two dedicated bands (895-905MHz and 940-950MHz) while providing sharp rejection (≥45dB) for all frequencies below 894MHz, ensuring clean signal transmission for target services.
DC/AISG Signal Support: Features integrated bypass for DC power and AISG control signals, enabling remote antenna unit management without disrupting filtered RF paths.
Surge Suppression: Incorporates robust lightning protection (10kA; 8/20µs pulse), shielding connected equipment from voltage surges in outdoor deployments.
Typical Application Scenarios
Critical Communications Infrastructure: Ideal for TETRA, CDMA, or specialized industrial systems operating in 900MHz bands where strict out-of-band rejection is essential to prevent interference.
Co-located Cellular Sites: Used in multi-operator towers to isolate specific bands (e.g., 900MHz utilities) from adjacent cellular signals (e.g., 700-800MHz LTE), reducing cross-system noise.
Ruggedized RF Enclosures: Deployed in outdoor cabinets or pole-mounted setups (via included Φ35-135mm clamps) for public safety networks, industrial IoT, or SCADA systems requiring weather resilience (IP65) and surge protection.
Technical Features
Optimized RF Performance: Delivers ultra-low insertion loss (≤0.6dB in primary passband) and high rejection (≥45dB@DC-894MHz), with PIM ≤-160dBc ensuring signal integrity. Available in single-unit (96310287) or dual-unit (96310288) configurations for flexible deployment.
High-Power Resilience: Handles continuous input power up to 200W and extreme peaks of 2000W (7-16 Female connectors), suitable for high-traffic or emergency communication networks.
Industrial-Grade Design: Features IP65-rated housing for dust/water resistance, operational range of 0°C to +55°C, and flexible pole/wall mounting. Compact form factor (Single: 396x252.5x77.8mm; Double: 396x252.5x161.8mm) simplifies integration.
