VITA 90 VNX+ Solutions

Introduction

Samtec’s VITA 90 VNX+ platform is a rugged blind-mate interconnect system for modular open-system architectures. It brings RF backplane, optical, and power connectivity together within the VITA 90 connector ecosystem, addressing embedded-system designs that need multiple signal and power domains across a compact, modular interface.

The platform includes the VITA 90.0 connector family and VITA 90.2 connector modules. Its technically notable features include SEARAY right-angle array technology, RF backplane performance up to 110 GHz, rugged optical support, and configurable mechanical and contact-interface options.

What it does

VITA 90 VNX+ provides interconnection between modules in a backplane-oriented system while supporting RF, optical, and power connectivity. The blind-mate architecture is intended to simplify engagement between compatible modules and mating interfaces in modular equipment.

VITA 90.0 connectors use Samtec’s SEARAY right-angle array technology and are offered with 13 mm or 19 mm stack-height options. VITA 90.2 modules extend the platform with full- and half-aperture configurations. Optical connectivity is available through MT optical ferrules, while RF connections can use size 16 or size 20 RF contacts.

For GPCC contacts, the platform supports 50 Ω and 75 Ω impedance options. Together with RF backplane performance specified up to 110 GHz, these options allow designers to select interfaces suited to the electrical and mechanical requirements of a given VNX+ implementation.

Applications

Potential uses that follow directly from the platform’s capabilities include:

• Modular embedded systems using VITA 90 VNX+ backplane connectivity
• Systems requiring combined RF, optical, and power interconnects
• Backplane designs with RF paths operating up to 110 GHz
• Equipment using MT-ferrule optical interfaces
• Designs requiring full- or half-aperture VITA 90.2 connector modules
• Modular assemblies where blind-mate connector engagement is required

Design considerations

System designers should account for the selected VITA 90.0 stack height, choosing between 13 mm and 19 mm options according to the mechanical arrangement of the mating modules. VITA 90.2 module selection also includes full- or half-aperture formats.

Interface planning should cover the required RF contact size—size 16 or size 20—as well as the applicable GPCC impedance option of 50 Ω or 75 Ω. Where optical links are needed, the design must accommodate the MT optical-ferrule interface. The platform’s RF, optical, and power capabilities should be considered together at the backplane and module level.
