SSMA Female 4-Hole Flange Mount RF Connector – Field Replaceable, 5.9mm Hole Spacing, 0.23mm Pin Diameter

SSMA Female 4-Hole Flange Mount Field-Replaceable RF Connector – Model SSMA-KFD1

The SSMA female 4-hole flange RF connector with a 0.23 mm pin and 5.9 mm hole spacing delivers metrology-grade performance in a miniature footprint. Engineered for 50 Ω systems from DC to 36 GHz, this field-replaceable connector is ideal for precision instruments that demand repeatable coupling.

Tight-Tolerance RF Metrics

Optimized for VSWR ≤ 1.25 with insertion loss ≤ 0.06 √F(GHz) dB, the SSMA female connector preserves phase linearity and low return loss for broadband verification tasks.

Miniature Mechanics, Maximum Stability

Its compact 5.9 mm bolt pattern increases panel density while maintaining rigid alignment under torque—perfect for ruggedized modules and portable analyzers using 4-hole flange mounts.

Use Cases in Dense RF Assemblies

Choose this 0.23 mm pin variant for low-power signal paths, calibration fixtures, and micro-coax transitions within high-channel-count test bays. Explore more options in our SSMA connector family.

Compliance and Sourcing
