Description
The 30dB 2W RF Fixed Attenuator is a high-performance microwave component designed to reduce the power of an RF signal by exactly 30dB, providing a precise 1000:1 power reduction. With a 2-Watt power handling capacity, it is optimized for low-to-medium power signal conditioning in precision environments where high isolation is required. This model is engineered for an ultra-wide frequency spectrum from DC to 18GHz, making it an essential tool for Ku-band satellite links, radar systems, and advanced laboratory testing of high-speed wireless technologies.
The attenuator features an SMA Male to SMA Female inline configuration, utilizing high-quality connectors designed to maintain electrical stability at microwave frequencies. It is constructed with thin-film resistive elements that provide exceptional frequency flatness and a low Voltage Standing Wave Ratio (VSWR) even at the upper limits of its 18GHz range. Housed in a ruggedized stainless steel or passivated brass body, it ensures superior durability and shielding, maintaining consistent attenuation accuracy across varying thermal and mechanical conditions.
