Product Overview
The MNA-738-100-X-41-160 is a carrier-grade 100W RF Attenuator engineered for the wide 698-3800MHz frequency band. It is a high-precision solution for signal leveling in 5G, 4G LTE, and specialized In-building Solutions (IBS). With an ultra-low Passive Intermodulation of -160dBc and robust 4.3-10 Female connectors, this attenuator ensures maximum signal integrity and minimal reflection (VSWR ≤1.25) even at high power levels.

Frequently Asked Questions
- Q1: How does a 100W power rating benefit my RF system?
- A: A 100W average power rating allows this attenuator to safely handle high-intensity signals from base stations. It prevents overheating and maintains stable attenuation levels, which is vital for protecting sensitive measurement equipment or balancing links in a high-capacity DAS.
- Q2: What is the importance of -160dBc PIM for 5G applications?
- A: Low Passive Intermodulation (PIM) ensures that the attenuator doesn't generate interference within the system. For 5G and LTE networks, a rating of -160dBc is essential to maintain high data throughput and prevent signal degradation, especially in multi-carrier environments.
- Q3: Does this attenuator support the new 3.5GHz 5G bands?
- A: Yes. The 698-3800MHz frequency range fully covers the major 5G sub-6GHz bands (n77, n78) as well as all standard 2G, 3G, and 4G LTE frequencies.
- Q4: Why is attenuation accuracy specified differently for various dB values?
- A: Maintaining a flat response over a broad 3.1GHz bandwidth is more challenging at higher attenuation levels. We provide specific Accuracy (±dB) ratings from 0.8 to 1.5 to ensure engineers can precisely calculate their link budget based on the selected attenuation.
- Q5: What are the advantages of the 4.3-10 connector type?
- A: The 4.3-10 connector is the modern industry standard for low-PIM performance. It is more compact than 7/16 DIN and provides a more stable electrical interface, ensuring consistent VSWR and PIM performance in demanding field conditions.
