646540-1

TE Connectivity AMP Connectors's 646540-1 sets new standards in Backplane Connectors - Hard Metric, Standard for high-speed test and measurement equipment. Optimized for oscilloscopes and spectrum analyzers, this connector series delivers unprecedented signal fidelity up to 70GHz. Its precision engineering meets the exacting requirements of 6G research and semiconductor characterization where measurement accuracy is critical.The Receptacle, Female Sockets interface incorporates patented compensation technology that reduces VSWR to 1.05:1 at 50GHz. The air-dielectric design minimizes dispersion effects in time-domain measurements.Utilizing F 11 mechanical design, this precision connector maintains 5 m alignment tolerance. The kinematic coupling mechanism ensures repeatable connections with sub-ps timing accuracy.With 88 coaxial channels, this solution supports multi-port device characterization. The optimized layout provides 90dB channel-to-channel isolation at 40GHz.The All configuration enables simultaneous power and signal delivery for active probe applications. The integrated DC blocks prevent low-frequency interference.The 0.079" (2.00mm) spacing achieves 70GHz bandwidth while maintaining 50 impedance control within 1%. The ceramic-loaded housing provides stable dielectric constant across temperature variations.The 8 contact arrangement minimizes ground loop interference. This symmetrical design reduces common-mode noise by 20dB in sensitive measurements.Engineered for Through Hole installation in metrology equipment, this connector features zero-force mating. The frictionless mechanism preserves calibration accuracy through 10,000 connect cycles.The Press-Fit method creates hermetic interfaces with less than 0.1pA leakage current. The gold-diffused contacts maintain stable RF characteristics after 500 mating cycles.The Gold plating provides exceptional surface smoothness (Ra < 0.05 m) for consistent RF performance. Testing shows insertion loss variation below 0.01dB/mm at 60GHz.With 30.0µin (0.76µm) gold deposition, the contacts achieve skin depth optimization for 70GHz operation. This coating thickness minimizes dispersion while preventing surface oxidation.
