New EECL SMX range of configurable switch matrixes for signal up to 30GHz with up to 8 common ports and 48 switched ports. These high-speed, USB and ethernet controlled RF full cross-bar switch matrixes are specifically designed for versatile and dynamic routing of RF signals. With a full cross-bar architecture, the switch matrices can switch any of its common ports to any of the I/O ports in dual path, offering unparalleled flexibility in routing and signal distribution. Custom configurations are available upon request. This solid-state matrix enables bi-directional RF paths over a broad frequency range of 16 kHz to 12 GHz (or up to 30 GHz), maintaining minimal insertion and return loss. Each port is internally DC-blocked and capable of handling up to 16V, making it durable and resilient for demanding RF environments. In contrast to mechanical switching solutions, the switch matrices solid-state design ensures each port is permanently matched to 50 ohms, including unselected ports, providing exceptional impedance matching ideal for vector network analyzer (VNA) extension applications. The module also integrates a precision-controlled internal oven, which can sustain stability over time, limiting signal drift to less than 0.02 dB. All signal paths have been designed to be equal in length, resulting in consistent phase and magnitude for each path. Two key applications are easy de-embedding of test setups and multi-port TDR measurements. Channel to channel isolation is exceptional at more than 80dB. Equipped with SMA on the 12GHz version and 2.92mm connectors for the 30GHz version, the switch matrix is suitable for automated test environments, with the added flexibility of USB and Ethernet control interfaces. For time-sensitive applications, the switch matrix supports the loading of predefined switching sequences, which can be triggered by logic signals, achieving rapid switching with microsecond-level timing. The module is also capable of standalone operation, powered directly through USB. EECL’s software suite seamlessly integrates with the modules, providing a powerful and user-friendly interface for configuring and controlling the system. Compatible with C, LabView, Python and MATLAB, the software allows for the automation of complex tasks and real-time data acquisition. Users can set up measurement configurations through an intuitive dashboard. Advanced features include automated script execution and customizable trigger conditions for precise timing. The software also supports remote access via Ethernet or USB, enabling control from any networked location, ideal for both lab-based setups and large-scale distributed testing environments. |
