SMP-type RF Coaxial Connector is a miniature push-on RF connector designed for high-frequency signal transmission in compact electronic systems. Featuring a 50Ω characteristic impedance and operating frequencies up to 40 GHz, it provides reliable electrical performance while occupying minimal installation space. Compared with conventional threaded RF connectors, the SMP-type RF Coaxial Connector adopts a push-in coupling mechanism, enabling quick mating and unmating while supporting high-density interconnection in microwave and millimeter-wave equipment.
SMP-type RF Coaxial Connector products are commonly manufactured with precision-machined contacts, gold-plated conductive surfaces, and high-performance dielectric materials to maintain stable insertion loss, return loss, and impedance consistency. Their compact dimensions, lightweight construction, and vibration resistance make them suitable for applications requiring reliable RF performance under demanding mechanical environments, including aerospace, satellite communications, military electronics, radar systems, and high-frequency communication equipment.
Yangzhou Jingcheng Electronics Co., Ltd. has specialized in the development and manufacturing of RF coaxial connectors, cable assemblies, and passive microwave components since 1999. Certified to ISO9001 and manufacturing in accordance with MIL, IEC, and GB standards, the company supplies more than 30 RF connector series and over 2,000 specifications, including SMP-type RF Coaxial Connector products for communications, aerospace, automotive electronics, industrial equipment, and microwave applications.
