Mini-Circuits Released New Butler Matrix Line
The company introduced five new models to support precise antenna beamforming and MIMO development.
Updated on Oct. 5, 2026 in Telecommunications
Mini-Circuits has released a new family of five Butler matrices designed for 5G and Wi-Fi testing environments. These devices facilitate controlled RF phase relationships to emulate multipath propagation conditions.
Why it matters
Engineers rely on these matrices to accurately simulate complex antenna beamforming and multiple-input multiple-output (MIMO) signal environments in the lab. This release provides a standardized toolset for testing high-frequency wireless performance.
The 4 x 4 series provides a 45° phase offset, while the 8 x 8 models offer 22.5° increments with frequency coverage extending up to 7250 MHz. Every unit features SMA connectors and undergoes 100 percent performance testing.
The players
Mini-Circuits
A manufacturer of RF, IF, and microwave components used in wireless communication and radar systems.
The details
The devices use passive components and phase-matched cables to ensure precise, repeatable signal paths. A Butler matrix acts as a beamforming network that manages multiple input and output channels simultaneously to simulate how radio waves interact with obstacles in a real-world environment. These paths are essential for testing how well wireless systems perform in crowded electromagnetic conditions.
Timeline

The Tech Race
This release expands the available toolkit for engineers testing against IEEE 802.11 MIMO standards. It targets the ongoing industry shift toward higher-density beamforming arrays that require precise phase control to maintain signal integrity.
These units are intended for use in laboratory and production test environments rather than consumer devices. Organizations developing 5G and Wi-Fi equipment can integrate these matrices immediately to refine antenna array performance.
The takeaway
The addition of these five models allows developers to scale their testing rigs for increasingly complex 5G network configurations. Prospective users should look for technical datasheets on the vendor website to match specific frequency ranges to their current lab equipment.
