The 1.85mm male 4-hole flange mount RF connector with 8.64 mm hole spacing and a 0.23 mm pin diameter ensures outstanding RF precision and long-term stability in high-frequency measurement and communication systems. Designed for 50 Ω impedance and operation up to 67 GHz, the 1.85-JFD1 supports repeatable, low-loss signal transmission for next-generation microwave instrumentation. Explore Mechanc’s complete range of RF connectors.

Return Loss and Insertion Loss Performance

The 1.85-JFD1 RF connector achieves VSWR ≤ 1.2 and insertion loss ≤ 0.06 √F(GHz) dB, maintaining superior signal integrity across the DC – 67 GHz bandwidth. Its precision-machined 1.85 mm male interface minimizes reflection and enables accurate vector network analyzer calibration and system-level testing. Learn more about our 1.85mm connectors.

Electrical Interface Precision and Contact Geometry

Each 1.85-JFD1 connector is built from passivated stainless steel and equipped with a gold-plated beryllium copper contact, delivering precise impedance control and stable contact resistance. Tight concentricity between the outer conductor and pin guarantees low phase deviation and reliable mating under high-cycle conditions. For serviceable designs, explore Mechanc’s field-replaceable connectors.

Mechanical Stability and Mounting Integrity

The 4-hole flange mount design ensures secure mechanical retention and vibration resistance in demanding test or production environments. Its 8.64 mm mounting pattern provides excellent torque stability and panel alignment, reducing mechanical strain and maintaining connector performance over repeated operations.
