MS-156 series subminiature coaxial switch, with compact design, height only 1.6mm, board space occupied 2.7mm x 2.7mm. Weight only 0.025g, support 100 mating/unmating cycles. The switch covers a wide frequency range from DC to 6 GHz.
The MS-156 Series is a 1.6 mm high subminiature coaxial switch designed for inspection of high‑frequency circuits in portable terminals, wireless LAN, POS terminals, GPS devices, and other small electronics. The switch redirects the circuit to an external plug for performance verification and returns to normal operation when the plug is removed.
Key features include low insertion loss (0.1 dB typical at 6 GHz), a compact 2.7 mm × 2.7 mm board footprint, lightweight construction (0.025 g), and durability of 100 mating/un‑mating cycles. The product is supplied on tape‑and‑reel, with optional vacuum caps, and complies with lead‑free material requirements.
