Product Overview
The MNL-25-27-SMA Band Pass Filter acts as a precision signal gatekeeper, specifically designed to allow frequencies between 2500 to 2700MHz to pass while efficiently blocking out-of-band interference. This passive RF component is essential for cleaning up signal noise in 4G LTE and radio communication circuits. With its compact design, low insertion loss (≤0.5dB), and reliable SMA-Female connectors, it is a perfect solution for In-building Solutions (IBS) and sensitive RF environments.

Frequently Asked Questions
- Q1: What is the primary function of this 2500-2700MHz band pass filter?
- A: It acts as a frequency-selective gate. It allows signals within the 2.5-2.7GHz band (commonly used for 4G LTE/LTE-A) to pass with minimal loss while suppressing unwanted signals outside this range by 35dB, significantly reducing interference.
- Q2: Why is "Insertion Loss" critical for RF filters in IBS applications?
- A: Insertion Loss refers to the power lost as the signal passes through the filter. With a very low loss of ≤0.5dB, this filter ensures that the signal strength remains high, maintaining coverage quality in in-building distributed antenna systems (DAS).
- Q3: Can this filter handle high-power signals from base stations?
- A: Yes. It is designed to handle an average power of 50 Watts and can withstand peak power up to 500 Watts. This makes it suitable for use with various transmit and receive equipment in commercial wireless networks.
- Q4: What does the IP60 rating mean for installation?
- A: The IP60 rating indicates that the unit is well-protected against dust ingress. It is designed primarily for Indoor Applications. For outdoor requirements where water resistance is needed, we offer customized IP65 or IP67 versions through our OEM service.
- Q5: Is customization available for different rejection levels or connectors?
- A: Absolutely. We provide professional OEM services. Whether you need higher rejection at specific frequencies, different connector types (like N-type or 4.3-10), or a different frequency band, our engineers are available 24/7 to provide technical support.
