1958191-1

Optimized for 5G infrastructure deployments, the 1958191-1 by TE Connectivity AMP Connectors delivers exceptional performance in Terminals - Wire Pin Connectors applications. These RF-shielded connectors maintain impedance stability up to 6GHz, making them ideal for mmWave antenna array interconnections. The gold-plated variants achieve <0.5dB insertion loss at 28GHz frequencies.The precision Circular - 0.070" (1.78mm) Dia specifications ensure controlled impedance matching in RF transmission lines. Circular pins feature proprietary surface finishing that reduces skin effect losses at microwave frequencies.With 0.390" (9.91mm) pin length, these terminals provide optimal RF grounding when used with quarter-wave transformer designs. The length tolerance of 0.01mm prevents phase distortion in phased array systems.The compact 0.918" (23.32mm) profile enables high-density packaging in small cell radio units. The low-profile design minimizes cavity resonance effects that could degrade signal quality.Compatible with {Wire Gauges}, these terminals maintain characteristic impedance within 1% variation, critical for maintaining VSWR below 1.2:1 in base station antenna feeds.Precision-controlled 0.105" ~ 0.140" (2.67mm ~ 3.56mm) ensures uniform dielectric spacing for consistent propagation velocity. The low-loss PTFE insulation material maintains stable r across temperature fluctuations.Insulated options include conductive variants that provide 360 EMI shielding, essential for preventing intermodulation distortion in multi-band carrier aggregation systems.The Crimp process utilizes gas-tight compression that prevents passive intermodulation (PIM) below -153dBc, exceeding 3GPP TS 37.104 requirements for 5G NR equipment.Natural, Red Stripe coding follows ETSI standards for quick identification of different frequency band connections in massive MIMO antenna systems.
