KMS-560A Series/Miniature RF Switch for Automotive

Overview

The KMS-560A series is a miniature RF switch developed for the inspection and measurement of high-frequency
automotive circuits up to 6GHz. The compact design simplifies RF circuit inspection during manufacturing.
Circuit performance can be verified by simply inserting the external plug into the board-mounted receptacle.
This action re-directs the circuit from normal condition to the plug side. Removing the plug restores the circuit
to its normal condition.
