A Legacy of Innovation: The History of Times Microwave Systems’ Multiport Connector Systems 

The journey of multiport RF connectors began with a single challenge: how to deliver more performance in less space for mission-critical defense platforms. Multiport RF connectors emerged as a game-changing solution—redefining what’s possible by consolidating multiple connections into a single, compact interface.  

Developed to thrive in high-vibration conditions, our M8^® connector system laid the foundation for a new era in RF interconnects. Since then, the evolution of multiport technology has followed the rapidly advancing needs of aerospace and defense systems. From the vibration-optimized V8 to the skin-penetrating P8, and the high-frequency MMP, each innovation has built on the legacy of the original M8. Each generation brings targeted improvements to meet emerging needs—reflecting our continuous drive to support the most demanding defense and aerospace applications. 

M8 Multiport Connector System: The Foundation 

The original M8 multiport connector system established the core advantages that would define the multiport approach. It delivered high-frequency performance, supporting frequencies up to 20 GHz with low insertion loss and excellent shielding. The system maintained superior phase stability even in extreme environments, with channel isolation exceeding 100 dB to minimize EMI and crosstalk. It also provided support for phase-matched and equalized assemblies, reducing cable routing complexity. The REACH/RoHS-compliant conductive plating provided 2,000 hours of salt fog resistance and 668 hours of sulfur dioxide resistance, ensuring excellent performance in both airborne and maritime applications. 

The M8 system delivered significant size reduction by eliminating bulky threaded connectors, substantially reducing the physical footprint required for multiple RF connections. Its compact design enabled higher cable density, integrating multiple RF paths into a single connector footprint and maximizing space efficiency. The keyed configurations improved installation accuracy by eliminating misconnection risks, significantly reducing the potential for costly wiring errors. 

The M8 system quickly established itself as the go-to solution for critical platforms including the F-15, F-18, P-8, and V-22, collectively logging hundreds of thousands of flight hours. 

V8 Multiport Connector: Enhanced Vibration Resistance 

As aircraft designs evolved to become faster, more agile, and incorporated more onboard systems, interconnect solutions required smaller, lighter, and more vibration-resistant connectors. Building on the legacy of the M8, Times Microwave Systems developed the V8 multiport connector. Key features of this variation include an improved spring-finger mechanism for increased stability and titanium construction to reduce weight and enhance corrosion resistance, all to meet the high-vibration requirements for next-gen aircraft. The design also incorporates lower insertion force for easier installation. The V8 became the preferred solution for advanced platforms including the F-35 and newer F-15 variants, where vibration performance was particularly critical. 

P8 Multiport Connector: Skin Penetration Applications

The success of the multiport concept led to customer demand for extending the technology to specialized applications. One key challenge was developing a connector that could effectively penetrate the aircraft skin for external systems—the P8 design was created specifically for this purpose. It features a unique locking mechanism enabling one-man, one-side installation and is optimized for extreme environmental conditions, including high altitudes and temperature fluctuations. The P8 variant has been successfully deployed on platforms including the E2/E2D Hawkeye and E7 Wedgetail, where its specialized capabilities provide critical advantages. 

Mini-Multiport Connector (MMP) System: Higher Density, Higher Frequency 

Building upon the legacy of high-density, low weight, and easy installation, the next generation of multiport is called the Mini-Multiport (MMP). The initial design was inspired by the MIl-DTL-38999 specification with a front release feature. The MMP system extends operating frequency to 40 GHz and features a design enabling custom footprint optimization. It provides even higher density with smaller contact diameters and offers direct PCB mount compatibility. Designed for modular scalability, the MMP allows integration with additional system components.  

Proven Performance Across Mission-Critical Platforms 

From fighter jets to electronic warfare platforms, multiport connectors have become an essential part of modern mission-critical systems. Our multiport evolution—from M8 to MMP—has enabled engineers to meet ever-tightening SWaP, performance, and installation demands. With each new variant, we’ve responded to the needs of real applications in the field, ensuring the highest reliability where it matters most.
