It uses a 2.24mm plug diameter interface and a snap-on fastening style, making it suited for board-level signal routing where space is tight and a clean RF path is needed up to 11 GHz. The gold-plated brass body and gold center contact plating handle repeated matings without corrosion concerns in controlled environments. ## What the RF Specs Mean for Your Signal Path The 11 GHz max frequency covers common wireless bands including Wi-Fi 6E and 5G sub-6 GHz, with headroom for higher-frequency harmonics. Insertion loss is rated at 0.3dB through the switch path, which is low enough that it won't eat into your link budget on short board-to-board runs. The internal switch lets you route the RF signal without an external relay, saving board area and part count. ## Mating Cycles and Mechanical Life The snap-on fastening gives a positive tactile lock when mated, and the gold-on-gold contact interface keeps resistance stable across those cycles. If you need a higher cycle count, the MS-162B sibling in the same family is rated for 12000 cycles but uses a larger 4mm plug diameter.","metaTitle":"Hirose MS-180(20) Coaxial Switch Receptacle, 50 Ohm, 11 GHz","metaDescription":"Hirose MS-180(20) SMT coaxial switch receptacle, 50 Ohm impedance, 11 GHz max frequency, 0.3dB insertion loss, internal switch, 100 mating cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"MS-180","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Internal Switch","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"100","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"0.3dB","Product Status":"Active","Connector Style":"Coaxial Switch - 2.24mm Plug Dia","Frequency - Max":"11 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"MS-180","Contact Termination":"Solder","Dielectric Material":"Liquid Crystal Polymer (LCP)","Operating Temperature":"-40°C ~ 85°C","Center Contact Plating":"Gold","Center Contact Material":"Copper Alloy"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/421a6d31e5f68b5020741a4fac04a67e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the impedance of MS-180(20)?","answer":"The MS-180(20) is a 50 Ohm coaxial switch receptacle, matching standard RF system impedance."},{"question":"Does MS-180(20) have an internal switch?","answer":"Yes, the MS-180(20) includes an internal switch feature for signal routing without an external relay."},{"question":"How many mating cycles does MS-180(20) have?","answer":"The MS-180(20) is rated for 100 mating cycles, suitable for assembly and service connections rather than frequent field swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/MS-180~120~2","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-180~120~2 when reusing this data.
