20dB 2W RF Fixed Attenuator SMA M/F 6GHz

Description

The 20dB 2W RF Fixed Attenuator is a high-performance passive component designed to reduce the power of an RF signal by exactly 20dB, effectively reducing the signal power to one-hundredth of its original level. With a 2-Watt power handling capacity, it is ideal for low-to-medium power applications where precision and signal integrity are paramount. This model is optimized for a wide frequency spectrum from DC to 6GHz, ensuring full compatibility with sub-6GHz 5G NR, Wi-Fi 6, GPS, and standard telecommunications bands.

The attenuator features an SMA Male to SMA Female inline configuration, allowing for seamless integration into existing signal paths or direct connection to test equipment. It is constructed using high-reliability resistive elements that provide excellent frequency flatness and a low Voltage Standing Wave Ratio (VSWR). The housing is typically manufactured from stainless steel or passivated brass, providing a ruggedized exterior that ensures consistent electrical performance and durability over hundreds of mating cycles.

Key Technical Advantages

• Precise 20dB Attenuation: Provides a reliable 100:1 power reduction, essential for balancing signal strength and protecting sensitive receiver front-ends or spectrum analyzer inputs from saturation.

• Broad 6GHz Bandwidth: Provides a versatile solution for a wide range of wireless technologies, maintaining high accuracy from DC through the 6GHz spectrum.

• Excellent Impedance Matching: Often used as a “pad” to improve the VSWR between two mismatched components, minimizing signal reflections and protecting upstream sources.

• Compact and Rugged Design: The 2W power rating is housed in a streamlined form factor, making it ideal for tight spaces in both laboratory and field environments.

• Durable SMA Interface: Features high-quality SMA connectors with gold-plated center contacts to ensure low contact resistance and long-term reliability.
