20dB 5W RF Fixed Attenuator SMA M/F 6GHz

Description

 The 20dB 5W 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 an enhanced 5-Watt power handling capacity, it is robust enough to manage moderate power loads from amplifiers and transmitters, making it ideal for applications that exceed the limits of standard 1W or 2W units. This model is optimized for a wide frequency spectrum from DC to 6GHz, ensuring full compatibility with sub-6GHz 5G NR, Wi-Fi 6, Bluetooth, and advanced microwave bands.

The attenuator features an SMA Male to SMA Female inline configuration, utilizing a precision threaded coupling mechanism that provides high mechanical stability and excellent RF shielding. It is constructed using high-stability resistive elements and premium PTFE dielectric to ensure a flat frequency response and low Voltage Standing Wave Ratio (VSWR) across its entire bandwidth. To support the 5W rating, the device typically features a ruggedized body designed to efficiently dissipate thermal energy, ensuring consistent attenuation accuracy even during continuous operation.
