The 133-3404-001 is an MCX 50 Ohm straight crimp type plug connector designed for use with RG-188 DS and RG-316 DS cables, featuring gold-plated contacts and a captivated contact design. This connector supports both solder and crimp attachment methods, with a crimp hex dimension of 0.151 inches (3.83 mm) and overall length of 0.598 inches (15.19 mm). It operates across a frequency range of 0–6 GHz with an impedance of 50 Ohms, delivering low insertion loss of 0.1 dB at 1 GHz and VSWR performance of 1.13 + 0.04f for RG-316 cable. The connector meets MIL-C-39012 environmental standards with 500 cycle durability, temperature range of -55°C to +125°C, and contact retention of 2.3 pounds minimum axial force. This connector is ideal for RF/microwave applications, telecommunications, and high-frequency signal transmission where reliable impedance matching and low signal loss are critical.
