3U OpenVPX SOSA-Aligned RF Card Assemblies
Modular, SOSA-Aligned RF Architectures for Mission-Critical Systems
X-Microwave designs and manufactures rugged 3U (and 6U) OpenVPX card assemblies aligned to open standards-based architectures including SOSA. These cards integrate complex RF and microwave signal chains with bias and control circuitry within a single VPX slot, enabling high-performance subsystem integration across aerospace and defense platforms.
Our architectures interface through VITA-compliant backplane and RT connectors, supporting interoperability with other RF and control cards within a common VPX chassis. Leveraging our extensive RF component ecosystem and engineering expertise, we deliver SWaP-optimized assemblies operating to ~100 GHz for both development and production programs.
Integrated RF & Control Architecture
The 3U OpenVPX design utilizes a clamshell H-Frame configuration that separates RF and control domains while maintaining dense integration. RF signal chains are implemented on one side of the housing, with bias and control circuitry on the opposite side. Signals are routed internally between RF and control boards and through the daughter card to the VPX backplane interface.
Microcontrollers and FPGAs can be incorporated to support customer-defined control schemes. RF and control circuits can also be combined and miniaturized as needed to maximize functionality within a single card.
From Modular Prototype to Rugged VPX Deployment
Development typically begins on the X-Microwave Modular Platform using configurable X-MWblocks and solderless interconnect technology. Engineers can configure, validate, and optimize complete signal chains prior to committing to enclosure hardware.
Walls, lids, and shielding are introduced during evaluation to simulate cavity effects and predict final enclosed performance. Once validated, the design is migrated into a rugged 3U VPX enclosure, with options for PCB consolidation and machined channelized RF paths to support production scalability and environmental requirements.
