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

Description

The 3dB 10W 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 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. 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 across its entire operating range.

Key Technical Advantages

• Precise 3dB Reduction: Delivers a reliable 2:1 power reduction, making it an essential tool for balancing signal strength and protecting equipment front-ends.

• 10W Medium-Power Rating: Features a heavy-duty thermal design that allows it to handle significantly higher power than standard low-power test attenuators.

• Excellent Thermal Dissipation: The finned heat-sink housing ensures that the resistive elements remain within their optimal temperature range for maximum accuracy.

• Impedance Matching (Pad): Frequently used to improve the VSWR between two mismatched components, reducing signal reflections and protecting upstream sources.

• Low VSWR: Precision-engineered internals minimize signal reflections, protecting signal sources and ensuring measurement accuracy across the DC-3GHz spectrum.
