Product Overview & Features
The MNF-863-40-NF is a high-performance 100W RF Bandpass Filter specifically engineered to enhance network signal quality. By providing a narrow passband (863-867MHz) with high stopband attenuation, it effectively improves the input selectivity of receivers and amplifiers while increasing isolation between transmitters. This is particularly critical in scenarios where antennas are mounted in close proximity, ensuring minimal interference and maximum reliability for 2G, 3G, 4G LTE, and modern In-building Solutions (IBS).

Frequently Asked Questions (Q&A)
- Q1: How does this filter benefit co-located antenna installations?
- A: When antennas are mounted close together, interference between transmitters and receivers is common. This filter increases the isolation between transmitters, preventing signal desensitization and ensuring each system operates without performance degradation.
- Q2: Can the MNF-863-40-NF improve the performance of my receiver?
- A: Yes. By enhancing the input selectivity, the filter effectively blocks out-of-band noise and strong interfering signals from adjacent bands, allowing the receiver to focus on the 863-867MHz range.
- Q3: What are the typical applications for this 100W bandpass filter?
- A: It is widely used in In-building Solutions (IBS), distributed antenna systems (DAS), and base station site sharing where narrow-band signal purity and high-power handling (up to 100W) are required.
- Q4: Is the rejection level sufficient for high-interference environments?
- A: Absolutely. With a rejection of ≥40dB starting just 2MHz outside the passband (at 869MHz), this filter provides a sharp rollout to suppress unwanted signals effectively.
- Q5: Is the design suitable for space-constrained installations?
- A: Yes, one of its core features is a compact and low-weight design, making it easy to integrate into modern, high-density telecommunication cabinets and equipment racks.
