10dB 10W RF Fixed Attenuator BNC M/F 3GHz

Description

The 10dB 10W RF Fixed Attenuator is a high-performance passive component designed to reduce the power of an RF signal by exactly 10dB, effectively reducing the signal to one-tenth of its original power level. With a robust 10-Watt power handling capacity, it is specifically designed to manage significant power loads from transmitters and amplifiers, stepping them down to safe levels for sensitive receivers or spectrum analyzers. This model is optimized for frequencies from DC to 3GHz, making it ideal for VHF, UHF, GPS, and standard telecommunications bands.

The attenuator features a BNC Male to BNC Female inline configuration, utilizing the classic bayonet-style coupling for quick and secure connections without the need for tools. To manage its 10W power rating, the device is housed in a ruggedized aluminum or brass body with integrated cooling fins, ensuring efficient heat dissipation to prevent thermal drifting and maintain attenuation accuracy during continuous operation. Constructed with premium PTFE insulation and high-stability resistive elements, it delivers a flat frequency response and consistent performance in demanding environments.

Key Technical Advantages

• Precise 10dB Reduction: Delivers a reliable 10:1 power reduction, making it an essential tool for protecting test equipment front-ends from high-power saturation.
