Mini-Circuits introduces Butler matrices for repeatable 5G and Wi-Fi MIMO testing.

Mini-Circuits introduces Butler matrices for repeatable 5G and Wi-Fi MIMO testing. Mini-Circuits has released a family of high-performance Butler matrices, designed to help engineers reproduce controlled RF phase relationships and multipath propagation conditions in laboratory and production test environments. Covering key Wi-Fi and 5G FR1 frequency bands, the five models provide bidirectional signal transfer between all inputs and outputs while maintaining controlled phase relationships, amplitude balance, and insertion loss across their operating bands. The Butler matrix architecture is particularly useful for antenna beamforming development and evaluation of MIMO transmitters and receivers. By providing multiple precisely related RF signal paths, the matrices allow engineers to emulate multipath conditions that normally occur during over-the-air transmission without requiring an OTA environment. Every unit is 100% tested for highly repeatable performance. The portfolio includes two 4 x 4 models and three 8 x 8 models, all with SMA connectors: * ZBLR-4X4-0672 - 4 inputs and 4 outputs covering 600 to 7250 MHz, with 7 dB typical loss and a 45° phase increment between adjacent outputs. * ZBLR-4X4E - 4 x 4 configuration covering 2000 to 8000 MHz, with 7 dB typical loss and a 45° phase increment. * ZBLR-8X8-0650 - 8 inputs and 8 outputs covering 600 to 5000 MHz, with 12 dB typical loss and a 22.5° phase increment. * ZBLR-8X8E - 8 x 8 configuration covering 2400 to 7200 MHz, with 10 dB typical loss and a 22.5° phase increment. * ZBLR-8X8-0672 - 8 x 8 configuration covering 600 to 7250 MHz, with 10 dB typical loss and a 22.5° phase increment. Designed for Controlled Phase and Amplitude Performance A key characteristic of the Butler matrix is its defined phase progression between adjacent outputs. The 4 x 4 models provide a 45° phase offset, while the 8 x 8 models provide a 22.5° offset. These phase relationships enable controlled excitation of multiple antenna paths, making the devices suitable for beamforming and MIMO test applications. The product design uses high-performance passive components and custom phase-matched cables to maintain phase and amplitude performance across the specified frequency bands. This approach provides low amplitude unbalance and controlled loss across the operating range, with every unit subjected to 100% testing. For applications requiring programmable path loss in addition to phase-controlled signal distribution, Mini-Circuits also offers multi-channel attenuators that can be used with Butler and other n x m matrices. These attenuators support individually controlled attenuation, fading, sweep and hop sequences, with USB and Ethernet control and automation capabilities through Python, LabVIEW and other programming environments.

Mini-Circuits introduces Mini-Bench(TM) RF measurement platform for streamlined power sensor testing.

Mini-Circuits introduces Mini-Bench(TM) RF measurement platform for streamlined power sensor testing. Mini-Circuits will introduce Mini-Bench(TM), a new RF test and measurement software platform designed to simplify instrument setup, improve workflow efficiency and provide engineers with enhanced tools for measurement visualization and analysis at the European Microwave Week 2026, October 6-8 at ExCeL London in Booth A40A. Mini-Bench provides a modern, intuitive user interface for Mini-Circuits' PWR-Series high-performance power sensors. The platform lets users control multiple USB- and Ethernet-connected instruments from a single interface while speeding up setup and configuration. Built on customer feedback and real-world application requirements, Mini-Bench streamlines common measurement tasks while maintaining access to advanced test capabilities. The software supports Windows, macOS, and Linux systems. Advanced Measurement and Analysis Tools Mini-Bench gives engineers and technicians a flexible environment to configure measurements and analyze RF signals. Customizable measurement displays allow users to organize information for specific test requirements, while graphical tools provide greater visibility into device and system performance. Measurement capabilities include graphical power trend plots, pulse and modulation profile traces, dual profile traces for high-resolution analysis, measurement averaging, offset and relative measurements, and markers with delta-marker calculations. Users can also export measurement data and graph traces and schedule recordings for longer-term testing and analysis. A simulated sensor capability enables users to evaluate the software and become familiar with its operation before connecting hardware. The Mini-Bench interface can display multiple sensor measurements simultaneously while providing detailed graphical views of pulse and modulation characteristics. Instrument status, measurement values, configuration controls, and graphical analysis are brought together in a single workspace, helping users move efficiently from setup through measurement and analysis. Designed for Mini-Circuits' PWR-Series Power Sensors Mini-Bench complements Mini-Circuits' expanding family of PWR-Series RF and microwave power sensors. The product family includes sensors covering frequencies up to 40 GHz and supports measurements from CW and single-tone signals to pulsed signals and modern digital modulation formats. Simplifying the RF Test Workflow By combining instrument control, measurement configuration, visualization and data analysis in one platform, Mini-Bench helps reduce the time engineers spend configuring test equipment and managing separate measurement workflows. Its intuitive navigation makes the platform accessible to new users while providing the measurement and analysis functionality experienced RF test engineers require. Mini-Bench software, supporting documentation and information on compatible PWR-Series power sensors are available on the Mini-Circuits website.
