Product Overview
The MNF-1820-155-N is a high-performance 200W Dual-Band RF Filter engineered to provide superior selectivity and isolation in modern 2G/3G/4G and 5G networks. Specifically designed for the 1885-1915MHz and 2010-2025MHz frequency ranges, it effectively mitigates interference by improving the input selectivity of receivers and increasing the isolation between closely mounted transmitters. With an IP67 weatherproof rating and ultra-low Passive Intermodulation (-155dBc), this filter is an ideal solution for both high-capacity indoor systems and rugged outdoor base station environments.

Frequently Asked Questions
- Q1: How does this filter help when antennas are mounted close together?
- A: When antennas are co-located, signals from one transmitter can desensitize the nearby receiver. This 200W RF Filter provides high out-of-band rejection, effectively "cleaning" the signal and providing the isolation needed to prevent crosstalk and system noise.
- Q2: What is the significance of the IP67 rating for this model?
- A: The IP67 rating ensures the filter is completely dust-tight and can withstand immersion in water up to 1 meter deep. This makes it perfect for outdoor rooftop installations where it is exposed to heavy rain, humidity, and dust.
- Q3: Can this filter handle the high power of 5G base stations?
- A: Yes, with a 200 Watts average power handling capability, it is built to manage the high energy levels found in macro base stations and high-power DAS nodes without thermal degradation.
- Q4: Does the low PIM of -155dBc improve data throughput?
- A: Absolutely. Passive Intermodulation (PIM) creates background noise that interferes with the uplink signal. By keeping PIM at ≤ -155dBc, the filter ensures a higher Signal-to-Noise Ratio (SNR), which directly results in more stable connections and higher data throughput for mobile users.
