KJAM - Multi-Port RF (D38999 III) Series

KJAM Multi-Port RF Series by ITT Cannon: High-Performance RF Connectors for Military & Aerospace Applications

The ITT Cannon KJAM Multi-Port RF Series delivers a modular, cost-effective solution for demanding applications in Radar, Electronic Warfare (EW) systems, military communications, and embedded computing. Designed in a 38999-style circular connector format, the KJAM Series ensures precise radial alignment between plug and receptacle through tight-tolerance keys and keyways.

Engineered for superior RF performance, the KJAM connectors feature a metal-web insulator that enhances RF isolation and provides exceptional EMI shielding—critical for high-reliability defense and aerospace systems.

• Supports SOSA-aligned architectures, including the High-Density J8 and Low-Loss J9 connector interfaces
• Optimized for mixed-mode applications, including RF and fiber optic integration
• Ideal for space-constrained platforms requiring high-density, high-performance interconnects

Whether you're designing next-generation military avionics, ground-based radar, or EW systems, the KJAM Series offers a rugged, scalable solution that meets the evolving demands of SOSA-aligned and modular open systems.
