Product Overview
The MNL-25-3-NM is a high-performance 25W RF Termination Load designed to provide a stable 50-ohm termination for wireless systems operating from DC to 3GHz. It is engineered to handle medium power levels up to 25 Watts while maintaining an exceptionally low VSWR of ≤1.20. Featuring a robust N-type Male connector, this dummy load is widely used in 2G/3G/4G and LTE In-building Solutions (IBS) to terminate unused ports in couplers, combiners, and amplifiers, ensuring system stability and preventing signal reflections.

Frequently Asked Questions
- Q1: What is the benefit of a 25W power rating for a dummy load?
- A: A 25W power rating offers a balance between compact size and high power handling. It is ideal for terminating the output ports of medium-power transmitters or DAS distribution components where a standard 2W or 5W load might overheat.
- Q2: Why is a low VSWR (≤1.20) important for system performance?
- A: VSWR (Voltage Standing Wave Ratio) measures how efficiently RF power is transmitted. A low VSWR of ≤1.20 means that more than 99% of the signal is absorbed by the load. This prevents reflected energy from returning to the source, which can cause interference or damage to active RF components.
- Q3: Can this termination be used for 5G applications?
- A: Yes, it supports frequencies up to 3GHz, which covers all standard 2G, 3G, 4G LTE bands, and early sub-3GHz 5G NR bands. For higher frequency 5G bands (like 3.5GHz or 3.8GHz), please contact us for our 3.8GHz or 4GHz rated models.
- Q4: Is the N-male connector durable for outdoor use?
- A: The N-type connector is renowned for its durability and reliable performance in high-frequency applications. It features a threaded coupling mechanism that provides a secure, weatherproof connection, making it suitable for both indoor and outdoor telecommunications infrastructure.
- Q5: Are these loads RoHS and REACH compliant?
- A: Absolutely. All Maniron RF terminations are fully RoHS and REACH compliant. This ensures the products meet international environmental standards, making them safe for use in global telecommunications projects.
