50 Ohm Coaxial Switch for RF Routing
The Hirose MS-147(01) is a coaxial switch receptacle from the MS-147 series, designed as a female socket with a 4.8mm plug diameter. It integrates an internal switch function, making it suitable for RF signal routing where a switching path is needed — common in antenna selection or test port isolation circuits. With a rated insertion loss of 0.8dB across the band, the signal attenuation stays within a predictable window for receiver chain budgeting.
Surface Mount Assembly and Push-Pull Fastening
The MS-147(01) mounts via surface mount solder terminations, with the shield and centre contact both soldered to the board. The push-pull fastening type means it mates and unmates by axial force — no threaded coupling or bayonet lock. On a production line or in a field swap, that speeds up engagement but relies on the board-level solder joints for retention against cable strain. Beryllium copper gives the centre pin good spring properties over the 12000-cycle life, while the phosphor bronze shell provides a corrosion-resistant ground path.
