Product Description
50-Ohm SMA Male Coaxial Termination Dummy Load 2W DC - 18 GHz
The ARS-4864 is a compact 50-ohm SMA male coaxial termination load designed to provide a known 50-ohm load at the end of an RF transmission line. Rated for 2 watts average power and covering DC to 18 GHz, it is suitable for RF testing, laboratory equipment, communications systems, transmitters, and other high-frequency applications.
The termination absorbs RF energy rather than allowing the signal to encounter an open circuit, helping minimize unwanted reflections and maintain a properly terminated transmission system.
