The SpectrumSeries RFM3111 is an ultra-wideband microwave transceiver with versatile local oscillator (LO), low phase noise, and fast tuning speed, packaged in a SOSA-aligned, low-SWaP 3U module. These versatile transceivers are open system architecture compliant and aligned in digital and RF system processing domains through OpenVPX, OpenRFM, and SOSA. Built to meet SOSA specifications as they emerge, open systems-focused users can exploit the architecture commonality benefits immediately. The design streamlines the deployment of the latest technology by increasing efficiency and maintaining interoperability and configurability. Alignment is achieved without compromising the company’s high standards for security and ruggedness. The challenges of digital and RF convergence, spectrum-fusion and maneuverability, complementary system interoperability and affordability are solved with OpenRFM and SOSA. This open architecture approach standardizes and streamlines the design, integration, and testing of RF and digital capabilities within embedded processing subsystems. OpenRFM design principles are compatible with prevailing embedded computing industry standards.
