This is an N-type 2W 6GHz attenuator with 50-ohm impedance. It functions as a unidirectional device (isolator), featuring an N male input and an N female output. With a VSWR of less than 1.3 and minimal forward insertion loss, it is widely used in communication systems and laboratory measurement setups to effectively protect equipment and ensure signal stability. It is suitable for the vast majority of amateur wireless communication enthusiasts.
