The MS-156HF Series is a subminiature coaxial switch designed for the inspection of high-frequency circuits in portable terminals. It features a space-saving, low-profile, and lightweight design, enabling efficient verification of antenna/circuit performance by simply inserting an external plug. This redirects the circuit from its normal condition to the plug side, and removing the plug restores the original state. The switch operates over a wide frequency range from DC to 6 GHz and offers features like low insertion loss and solder wicking prevention.
