It is a same-series adapter — both ends are SMA, so it does not cross to another interface. The center conductor transitions from female to male, making it the piece you reach for when your cable ends in a jack and the instrument port expects a plug. The body is stainless steel, the dielectric is PTFE, and the center contacts are beryllium copper with gold plating. Rated for 1000 mating cycles at 50 Ohms up to 18 GHz, it handles repeated connect-disconnect in test setups or field-swap scenarios without the contact wear you'd see on a lower-cycle adapter. ## What the 18 GHz and 1000 Cycles Mean on the Bench The 18 GHz frequency ceiling is the point where the VSWR starts climbing — stay under that for a clean launch. The 1000-cycle rating is double what many SMA adapters carry; the gold-over-beryllium copper contacts handle the wipe without fretting.","metaTitle":"HRMP(PO)-HRMJ SMA Adapter, Plug to Jack, 50 Ohm, 18 GHz","metaDescription":"HRMP(PO)-HRMJ SMA to SMA adapter, straight plug-to-jack, female-to-male center contacts. 50 Ohm impedance, 18 GHz max frequency, 1000 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","Style":"Straight","Series":"HRM","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"-","Adapter Type":"Plug to Jack","Body Material":"Stainless Steel","Center Gender":"Female to Male","Mating Cycles":"1000","Mounting Type":"Free Hanging (In-Line)","Adapter Series":"SMA to SMA","Fastening Type":"Threaded, Threaded","Insertion Loss":"-","Product Status":"Active","Conversion Type":"Same Series","Frequency - Max":"18 GHz","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Base Product Number":"HRM","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-55°C ~ 85°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper","Convert To (Adapter End)":"SMA Plug, Male Pin","Convert From (Adapter End)":"SMA Jack, Female Socket"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$34.7500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/eccc2c1fb7fe066349e71a69fe07f20f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the HRMP(PO)-HRMJ a female-to-male SMA adapter?","answer":"Yes.
