The stainless steel body and PTFE dielectric support a frequency range up to 12.4 GHz with a typical insertion loss of 0.1 dB. The gold-plated beryllium copper center contact is rated for 1000 mating cycles, making it suitable for test equipment, instrumentation, and RF interconnect applications where repeated connect/disconnect is expected. ## Key RF Performance Specs The 50 Ohm impedance matches standard RF system lines, and the 12.4 GHz maximum frequency covers L, S, C, and most of X band. The 0.1 dB insertion loss is tight for an SMA at this frequency. ## Lifecycle Status: Last Buy — Plan Your Final Order The HRM-302S is in Last Buy status. This means Hirose has announced end-of-life, and the final production window is open. Once stock is exhausted, no further manufacturing is planned. For a BOM that requires this exact part, the next step is to secure quantity against an RFQ before supply dries up. There is no official successor listed in the HRM series; a cross-reference to a pin-compatible SMA receptacle from another manufacturer (e.g., Amphenol RF, Johnson/Cinch) should be evaluated for long-term production needs. Panel mount with a flange — the connector bolts through a panel cutout, and the threaded coupling nut secures the mating plug. The extended insulation feature (noted in the spec) provides additional dielectric creepage distance, helpful in high-voltage or high-altitude applications where partial discharge is a concern.","metaTitle":"Hirose HRM-302S SMA Receptacle, 50 Ohm, 12.4 GHz, Last Buy","metaDescription":"Hirose HRM-302S SMA receptacle, female socket, 50 Ohm, 12.4 GHz max, 0.1 dB insertion loss, 1000 mating cycles.
