20dB 100W RF Fixed Attenuator N M/F 3GHz

Description

The 20dB 100W RF Fixed Attenuator is a high-capacity passive component designed to reduce the power of an RF signal by exactly 20dB, providing a precise 100:1 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 safe levels for direct input into 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
