Description
The SMC Female (Jack) Solder Type Connector for .141/RG402 is an ultra-stable RF interface engineered for applications where signal leakage and phase stability are paramount. Semi-rigid cables like .141 (RG402) are the gold standard for high-frequency microwave systems due to their solid copper outer jacket, which offers 100% shielding effectiveness. This SMC connector is precision-machined to allow the cable’s outer conductor to be soldered directly to the connector body, creating a continuous, fused electrical path that eliminates the variables associated with mechanical crimping.
Operating from DC up to 10 GHz, the SMC interface utilizes a threaded #10-32 coupling mechanism. This provides a secure, vibration-resistant connection that is significantly more stable than snap-on alternatives, making it ideal for military avionics and high-performance wireless infrastructure. The connector is manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation to ensure low VSWR (Voltage Standing Wave Ratio) and exceptional thermal stability during the soldering process and throughout its operational life.
Key Technical Advantages
-
Seamless Solder Termination: The direct-solder design for the outer jacket and center conductor ensures maximum shielding effectiveness and the lowest possible return loss at microwave frequencies.
-
RG402 / .141 Precision Fit: Specifically calibrated to the dimensions of 0.141-inch semi-rigid and conformable cables, ensuring perfect mechanical alignment and 50-Ohm impedance matching.
