Product Overview
The MNF-816/869-150W-NM/F is a high-power RF Cavity Filter specifically engineered to manage signal transmission and attenuation within the 816 to 869MHz range. As a critical Band Pass solution, it effectively isolates specific frequencies while providing a steep rejection of over 60dB for out-of-band noise. With its robust 150W average power handling and IP65 rating, this filter is widely used in 2G to 5G infrastructure, ensuring high reliability for both indoor and outdoor in-building solutions.

Frequently Asked Questions
- Q1: Why is the 150W power handling significant for this cavity filter?
- A: 150W Average Power handling allows this filter to be used at the output of high-power base stations or repeaters without the risk of thermal damage or signal distortion. It ensures the system remains stable even under high-load continuous transmission.
- Q2: What benefit does a 60dB rejection level provide at DC-811MHz?
- A: A rejection of >60dB is exceptionally high, meaning it suppresses interfering signals by a factor of 1,000,000. This protects the 816-869MHz passband from lower-frequency noise, ensuring crystal-clear communication for LTE and 5G services.
- Q3: Can this filter be used in outdoor environments?
- A: Yes. The IP65 rating confirms that the unit is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for rooftop deployments or outdoor DAS installations alongside the wide storage temperature range.
- Q4: Why does this model feature an N-Male to N-Female connector configuration?
- A: The N-Male/N-Female setup allows for easy "in-line" integration into existing cable runs without the need for additional adapters. This "plug-and-play" capability simplifies installation in crowded equipment racks or distributed antenna systems.
- Q5: How does the cavity design impact the filter's weight and size?
- A: While cavity filters are traditionally larger, our design focuses on being compact and low weight without sacrificing the high Q-factor needed for sharp frequency selection. This makes it easier to mount on lightweight poles or within small indoor enclosures.
