SA18NMNF25W-03

Attenuators Overview

The SA18NMNF25W-03 is a fixed attenuator manufactured by Fairview Microwave, designed for RF interconnect applications. It provides a nominal attenuation of 3 dB across a frequency range from 0 Hz to 18 GHz. The device features N-type connectors, with a male plug on one end and a female jack on the other, ensuring compatibility with standard 50 Ohm systems. It is rated for a continuous power handling capacity of 25 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.6. The unit utilizes a heatsink body constructed from black aluminum to manage thermal dissipation effectively. Physical dimensions include a length of 114.3 mm, and it operates within a temperature range of -55°C to +125°C.
