1.Product Description：
Huizhou Antenk Electronics Co Ltd manufactures seven by seven flange mount SMA straight receptacle to deliver stable high frequency radio frequency signal interconnection for printed circuit boards. This PCB flange mounted coaxial receptacle adopts Hpb59‑1 brass shell, QSn6.5‑0.1 phosphor bronze contact pin and PTFE insulating dielectric with gold plating on critical contact areas, complete dimensional information is shown on engineering drawing for seven by seven flange footprint reference, it features fifty ohm characteristic impedance, DC to three gigahertz working frequency, one thousand volt dielectric withstanding voltage, insulation resistance no less than five thousand megaohm and works from minus fifty five degree Celsius to one hundred fifty five degree Celsius. Users fix the receptacle onto circuit board following official mounting drawing and complete soldering work then mate with compatible SMA plug to realize reliable RF signal transmission. Operators must follow drawing dimensional tolerances for PCB design avoid excessive axial mating force to prevent internal contact deformation and store components inside dry environment to safeguard gold plating surfaces against corrosion. Unlike competitors buying outsourced parts Antenk performs full in house workflow covering metal stamping precision turning assembly and comprehensive laboratory performance inspection. Our factory holds ISO9001 ISO14001 IATF16949 and UL certifications and more than seventy percent finished goods export globally. This receptacle suits wireless communication modules GPS hardware and precision measuring instruments. Please send your plating requirement packing option and project specifications for free sample evaluation and full technical document support.
PTFE Dielectric RF Socket utilizes high performance PTFE material as insulating medium to guarantee stable high frequency signal transmission under varied operating temperature conditions.
Gold Plated Coaxial Jack features gold plating on key contact zones to lower contact resistance and deliver outstanding anti corrosion performance for long term RF connection.
Flange Mount RF Connector adopts square flange fixing structure for secure positioning on printed circuit board before soldering operation.
