Rated at 50 Ohms impedance and specified to 12.4 GHz maximum frequency, it covers the L through X bands with an insertion loss of just 0.1 dB. That loss figure is tight enough for sensitive receive paths or precision test setups where every tenth of a dB matters. ## Cable Prep and Termination Sequence This plug terminates to RG-142B with a solder centre contact and a crimped shield termination. The PTFE dielectric requires clean, square cuts — any nick in the dielectric or braid will shift the impedance at the launch. Threaded fastening gives a positive mechanical lock.","metaTitle":"Hirose HRM-202(40) SMA Plug, 50 Ohm, 12.4 GHz, RG-142B","metaDescription":"Hirose HRM-202(40) SMA plug, male pin, 50 Ohm impedance, rated to 12.4 GHz with 0.1 dB insertion loss.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"HRM","Package":"Bulk","Features":"-","Includes":"2 pcs - 1 Connector, 1 Heat Shrink","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"RG-142B","Body Material":"Stainless Steel","Housing Color":"Gold","Mating Cycles":"1000","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Threaded","Insertion Loss":"0.1dB","Product Status":"Active","Connector Style":"SMA","Frequency - Max":"12.4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"HRM","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-30°C ~ 85°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.2400","stockQuantity":14,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the impedance of HRM-202(40)?","answer":"The HRM-202(40) is a 50 Ohm SMA plug, specified for RG-142B cable, with a maximum frequency of 12.4 GHz."},{"question":"What cable is HRM-202(40) compatible with?","answer":"It is designed for RG-142B cable — a double-shielded, PTFE-dielectric coax.
