20dB 10W RF Fixed Attenuator N M/F 3GHz

Description

 The 20dB 10W RF Fixed Attenuator is a high-performance passive component designed to reduce the power of an RF signal by exactly 20dB, providing a precise 100:1 power reduction. With a robust 10-Watt power handling capacity, it is engineered to safely manage moderate power loads from transmitters and amplifiers, stepping them down to safe levels for spectrum analyzers, power meters, and receivers. This model is optimized for a frequency spectrum from DC to 3GHz, ensuring full compatibility with 4G/LTE, VHF/UHF broadcast, and standard telecommunications bands.

The attenuator features an N-Type Male to N-Type Female inline configuration, utilizing a threaded coupling mechanism for a secure, low-loss, and vibration-resistant connection. To support its 10W rating, the device is housed in a ruggedized anodized aluminum heat-sink body with integrated cooling fins, which facilitates superior heat dissipation and prevents thermal drifting of the attenuation value. Manufactured with high-stability resistive elements and premium PTFE insulation, it delivers a flat frequency response and consistent performance in both laboratory and demanding industrial field environments.
