The gold-plated phosphor bronze body and gold centre contact keep insertion loss to 0.4 dB up to 11 GHz, making it suitable for antenna diversity, power-detect, or signal-routing circuits in wireless modules, IoT gateways, and compact radio assemblies. The surface-mount termination and snap-on fastening suit automated assembly in high-volume production. ## 50 Ohm Impedance and 11 GHz Bandwidth The 50 Ohm characteristic impedance matches standard RF system impedance — no impedance discontinuity at the connector interface. The 11 GHz upper frequency limit means the switch receptacle passes signals up to the Ku-band without excessive loss; above that frequency the 0.4 dB insertion loss spec no longer holds. ## Internal Switch and 100 Mating Cycles The internal switch feature means the receptacle has a switching contact that is normally closed (or in a defined state) when no plug is inserted, and opens when the 4mm plug mates. This is used for antenna-switching applications where the internal termination or second path is engaged when the external antenna is disconnected. The 100 mating cycle rating is adequate for field-swap or test applications but not for high-cycle production test interfaces — the gold plating on both body and centre contact helps maintain low contact resistance through those cycles. ## Surface-Mount Assembly and Solder Termination Surface-mount mounting and solder termination on both shield and centre contact mean the receptacle is placed and reflow-soldered alongside other SMD components — no hand-soldering or through-hole staking. The gold body finish provides a solderable surface and corrosion resistance. The single-port, female socket configuration mates with a male 4mm plug with snap-on fastening, giving a positive tactile engagement without a threaded coupling nut.","metaTitle":"Hirose MS-156C3 Coaxial Switch Receptacle, 50 Ohm, 11 GHz","metaDescription":"Hirose MS-156C3 coaxial switch receptacle, 50 Ohm, 11 GHz max, 0.4 dB insertion loss, 100 mating cycles, SMT, gold body.
