The MS-147 Series is an ultra-small RF connector with an integrated switch, designed for high-frequency applications up to 6GHz. Ideal for portable terminal interfaces and microwave board inspection, this series offers low insertion loss, a low profile (3.9mm height), and lightweight construction (0.11g). It features a normally closed (NC) circuit that opens when a plug is mated, enabling vertical mounting near antennas for signal switching or external antenna connections. The series is auto-insertable and RoHS compliant, ensuring efficient manufacturing and environmental responsibility.
