20dB 10W RF Fixed Attenuator N M/F 3GHz

Description

The 20dB 10W 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 robust 10-Watt power handling capacity, it is 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 compatibility with VHF, UHF, GPS, and standard cellular bands.

The attenuator features an N-Type Male to N-Type Female inline configuration, utilizing a threaded coupling mechanism for a secure, low-loss connection. To support its 10W rating, the device is housed in a ruggedized aluminum or brass body with integrated cooling fins, which facilitates efficient heat dissipation and prevents thermal drifting. Manufactured with high-stability resistive elements and premium PTFE insulation, it delivers a flat frequency response and consistent performance in both laboratory and industrial field environments.

Key Technical Advantages
