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.","metaTitle":"Hirose MS-147(01) Coaxial Switch Receptacle, 50 Ohm, 6 GHz","metaDescription":"Hirose MS-147(01) coaxial switch receptacle, 50 Ohm impedance, 6 GHz max frequency, 0.8dB insertion loss, 12000 mating cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"MS-147","Package":"Bulk","Features":"Internal Switch","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"-","Body Material":"Phosphor Bronze","Housing Color":"Gold","Mating Cycles":"12000","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Push-Pull","Insertion Loss":"0.8dB","Product Status":"Active","Connector Style":"Coaxial Switch - 4.8mm Plug Dia","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"MS-147","Contact Termination":"Solder","Dielectric Material":"Polyamide (PA), Nylon","Operating Temperature":"-30°C ~ 85°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4604","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5bfe802b766586c4e37091a8cfd2085d.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/MS-147~101~2","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/hirose-electric-co-ltd/MS-147~101~2 when reusing this data.
