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

Description

The 3dB 20W RF Fixed Attenuator is a high-performance passive component designed to reduce the power of an RF signal by exactly 3dB, effectively cutting the signal power in half. With a robust 20-Watt power handling capacity, it is specifically built to manage substantial power loads from transmitters and amplifiers, stepping them down to safe levels for sensitive receivers or measurement equipment. This model is optimized for a wide frequency spectrum from DC to 3GHz, ensuring full compatibility with VHF, UHF, GPS, and standard cellular 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 20W 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.

Key Technical Advantages
