Main Product Introduction
The ML-BF-960-NF is a high-performance band-pass filter optimized for the sub-1GHz cellular spectrum. Engineered for reliability, it features a robust 30W power handling capacity and exceptional out-of-band rejection of ≥60dB, specifically targeting interference in the 100-500MHz and 1200-2000MHz ranges. With a VSWR of ≤1.3:1, it maintains high impedance matching to minimize signal reflections. The unit is housed in a durable aluminum enclosure with a professional black paint finish and standard N-Female connectors, weighing 0.8 KG. This filter is an essential component for maintaining spectral purity in complex multi-carrier IBS and DAS environments.
Application Scenarios
- In-Building Solutions (IBS): Isolating low-band cellular signals to prevent interference from internal building systems.
- Distributed Antenna Systems (DAS): Ensuring uniform signal quality across the 800MHz and 900MHz bands in large venues.
- Spectral Cleaning: Removing unwanted noise from low-frequency radio sources and higher-frequency harmonics.
- Co-location Interference Mitigation: Protecting sensitive low-band receivers from nearby high-frequency transmitters.

FAQ
- How does the 60dB attenuation benefit my DAS network?
- The ≥60dB attenuation provides extreme suppression of signals outside the passband. By blocking noise in the 100-500MHz and 1200-2000MHz ranges, it ensures that only the 791-960MHz signal is amplified, reducing the noise floor and improving call quality.
- What is the power limit for the ML-BF-960-NF?
- This filter supports a maximum input power of 30W. This makes it perfectly suited for the distribution layers of an IBS network, remote radio units, and small cell installations.
- Why is the VSWR rating of 1.3:1 important?
- A VSWR of ≤1.3:1 indicates excellent impedance matching. It ensures that signal reflections are kept to a minimum, protecting your active equipment and maximizing the efficiency of power delivered to the antenna.
- Is this filter compatible with standard infrastructure cabling?
- Yes, it utilizes industry-standard N-Female connectors and 50Ω impedance, making it fully compatible with standard coaxial cables and RF components used in professional telecommunications.
