Introducing the Switch Matrix

EECL has extensive experience in the design and manufacture of high performance microwave switch matrices, with capability up to 44 GHz. Our solutions are engineered to deliver low loss, high isolation, and excellent repeatability, ensuring reliable performance in demanding environments. We provide fully bespoke designs tailored to project requirements, from compact configurations to large, highly complex routing systems. With inhouse RF simulation, precision mechanical engineering, and advanced test facilities, we control the entire development process to guarantee quality, scalability, and long-term dependability of every switch matrix we deliver.

To achieve best-in-class performance, our switch matrices incorporate several proprietary techniques and in-house capabilities that set us apart. We utilise custom microwave absorber integration and precision shielding gasket dispensing to minimise interference and achieve exceptionally compact designs without compromising performance. Each network is characterised using Time Domain Reflectometry (TDR), enabling us to guarantee consistency and repeatability in both phase and magnitude across every path. Thermal stability is ensured through integrated oven based temperature control, while our ultra-fast, fully reconfigurable firmware and control systems provide unmatched flexibility and responsiveness. These innovations allow us to deliver switch matrices that combine superior RF performance, reliability, and scalability in ways no other provider currently matches.

Our switch matrices are designed with maximum flexibility in mind, available as either compact benchtop units or fully integrated rack-mounted systems. They can be configured with virtually any number of ports and customised to match the exact routing requirements of each application. Control is provided via Ethernet or USB interfaces, with intuitive LED indicators that clearly display active paths and ports in real time. For highspeed test environments, intelligent sequencing can be programmed through TTL trigger lines, enabling automated path selection and significantly accelerating measurement workflows. This combination of adaptability, ease of use, and intelligent control ensures our solutions seamlessly into any customer’s setup while delivering exceptional performance.

Configurations



Our USB and Ethernet controlled (12GHz or 30GHz) matrices can be supplied as a bench module for 16 switched ports or rack mounted for 16 to 1024 switch ports.  The number of common ports on each path can be configured as 1 or 4.  Each matrix is dual path and full cross bar functionality which means you can connect any of the common ports to any of the switch ports. The switches utilise solid state technology and are oven stabilised for near zero drift performance meaning a single calibration (in phase and magnitude) can be used for all paths. The configurations can be tailored for reflective or absorptive (port always 50ohm matched) on the non-selected ports. Each port is DC blocked to 16V.

Equipped with SMA on the 12GHz version and 2.92mm connectors for the 30GHz version (other connector types available on request), the matrices are suitable for automated test environments, with the added flexibility of USB and Ethernet control interfaces. For time-sensitive applications we support 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. We can also allow access to the powerful onboard CPU for all sorts of custom applications.

The module features a webserver for direct connection and control over a browser.

Additional Options:

– Additional common ports (4 per path) to connect extra equipment
– Absorptive ports with enhanced isolation to provide 50 Ohm to each port and an additional 30dB isolation giving > 100dB

Rack mount switch matrix can be configured with frequency extender and bypass switch if required.
