40dB 100W RF Fixed Attenuator N M/F 3GHz

Description

The 40dB 100W RF Fixed Attenuator is a high-capacity passive component designed to reduce the power of an RF signal by exactly 40dB, providing a massive 10,000:1 power reduction. With a robust 100-Watt power handling capacity, it is engineered to safely manage high-power outputs from transmitters and power amplifiers, stepping them down to micro-watt levels compatible with sensitive spectrum analyzers, power meters, and receivers. This model is optimized for frequencies from DC to 3GHz, making it a vital tool for 4G/LTE, VHF/UHF broadcast, and industrial RF applications.

The attenuator features a rugged N-Type Male to N-Type Female inline configuration with a high-reliability threaded coupling. To effectively manage the significant heat generated by 100W of power, the device is housed in a large-format anodized aluminum heat-sink body with longitudinal cooling fins. This design ensures maximum thermal dissipation and prevents attenuation drift during high-duty-cycle operations. Manufactured with premium PTFE dielectric and high-stability resistive film, it maintains exceptional frequency flatness and low VSWR throughout its service life.

Key Technical Advantages

• High-Power 100W Capacity: Specifically designed for high-energy RF environments where standard laboratory attenuators would suffer immediate thermal failure.

• Extreme 40dB Power Reduction: Delivers an accurate 10,000-fold reduction in signal strength, allowing for the direct measurement of high-power transmission lines with ultra-sensitive equipment.
