40dB 20W RF Fixed Attenuator N M/F 3GHz

Description

The 40dB 20W RF Fixed Attenuator is a high-performance passive component designed to reduce the power of an RF signal by exactly 40dB, providing a precise 10,000:1 power reduction. With a robust 20-Watt power handling capacity, it is engineered to safely manage significant power loads from transmitters and amplifiers, stepping them down to safe levels for 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 standard telecommunications applications.

The attenuator features an N-Type Male to N-Type Female inline configuration with a high-reliability threaded coupling mechanism. To effectively manage the heat generated by 20W of continuous power, the device is housed in a ruggedized anodized aluminum heat-sink body with longitudinal cooling fins. This design ensures maximum thermal dissipation and prevents attenuation drift during continuous operation. Manufactured with premium PTFE dielectric and high-stability resistive elements, it maintains exceptional frequency flatness and low VSWR throughout its operating life.
