Product Overview
The 25W RF Attenuator (DC-3GHz) is a high-power passive device engineered for precise signal level control across 2G/3G/4G and LTE frequency bands. Capable of handling an average power of 25 Watts, this attenuator features a robust N-male to N-female connector configuration and a black heat-sink finish for optimal thermal management. It is widely utilized in In-building Solutions (IBS), lab testing, and base station equipment to protect sensitive receivers and balance signal distribution.

Frequently Asked Questions
- Q1: How does this 25W attenuator manage heat during continuous operation?
- A: It features a high-grade aluminum heat-sink body with a black anodized finish, specifically designed to dissipate thermal energy. This ensures stable performance even when handling its full 25W average power in high-temperature environments.
- Q2: Why is the attenuation accuracy different for higher dB values?
- A: For lower attenuation (3-10dB), accuracy is as tight as ±0.5dB. As attenuation increases to 40dB, the cumulative tolerance of the internal resistive elements slightly expands to ±1.5dB, which remains well within industry standards for DAS and lab testing.
- Q3: What are the primary applications for this device in In-building Solutions (IBS)?
- A: It is primarily used to reduce signal strength at the input of amplifiers or to balance the coverage between different floors/areas, ensuring that mobile devices receive an optimal signal level without overloading the receiver.
- Q4: Can this attenuator be customized with different connector types?
- A: Yes. While N-type is standard, we offer OEM customization for other interfaces such as 4.3-10, SMA, or DIN (7/16) to match your specific system architecture and PIM requirements.
- Q5: Is this product suitable for 5G Sub-3GHz networks?
- A: Absolutely. With a frequency range up to 3GHz, it fully supports 2G, 3G, 4G LTE, and major 5G NR bands (such as n41 and n78 below 3GHz), providing a future-proof solution for your network infrastructure.
