6U VPX Single Channel Down-Converters SOSA-Aligned

Open.Tech’s family of 6U VPX wideband RF down-converters offers scalable RF performance for embedded EW, SIGINT, and radar systems. Aligned with SOSA and VITA 48.2 mechanical standards, these modules deliver high-fidelity RF-to-IF conversion across the 2 GHz–18 GHz spectrum, with IF outputs ranging from 0.75 GHz to 6.0 GHz.

With a choice of 1, 2, or 3 RF inputs, this product family provides system designers with flexible options for sensor fusion, cross-pole/N-channel configurations, or dedicated band targeting. Each module features pre-selection filtering, gain equalization, and >60 dB dynamic range to enable digitizer-ready signal chains.

Available in conduction-cooled, 1.0” pitch designs, these down-converters integrate cleanly into harsh environment 6U VPX platforms. Support for external 10 MHz or 100 MHz clock references ensures coherent operation across multi-module systems.
