SSMA Female 4-Hole Flange Mount RF Connector – Field Replaceable, 5.9mm Hole Spacing, 0.38mm Pin Diameter

SSMA Female 4-Hole Flange Mount Field-Replaceable RF Connector – Model SSMA-KFD3

Featuring a 0.38 mm pin and 5.9 mm hole spacing, this SSMA female 4-hole flange connector is purpose-built for durability in high-mate-count fixtures. It supports 50 Ω from DC to 36 GHz with a field-replaceable interface for fast serviceability.

Low Loss, Low Reflection

Engineered for VSWR ≤ 1.25 and insertion loss ≤ 0.06 √F(GHz) dB, it maintains excellent return-loss profiles across microwave bands.

Mechanical Endurance in a Small Footprint

The reinforced flange and 5.9 mm bolt circle preserve planarity and alignment during frequent torque cycles—ideal for compact panels using 4-hole flanges.

Application Focus

The 0.38 mm pin is a versatile choice for LO distribution, RF routing in PXI/LXI chassis, and dense front ends. See more configurations within our SSMA connectors.

Procurement and Compliance

Gold-plated BeCu contacts and stainless housings provide corrosion resistance and long life; all variants align with our broader RF Connector Catalog.
