Why did you pick Spectrum Control’s Butler Matrix family as the featured product for the month?
I selected Spectrum Control’s Butler Matrix family to feature because it offers distinct advantages that make it stand out in WiFi MIMO testing. One of the family’s key differentiators is that each Butler Matrix simplifies the process of setting up a well-conditioned test channel, saving valuable setup time. The ability to quickly achieve a low Condition number is particularly important, as it indicates a well-conditioned channel capable of supporting the highest achievable speeds. This consistency in results makes it a highly reliable option for accurate MIMO testing.
Alternatively, without this product, you would need to manually align your test setup for each frequency range and scenario, which can be time-consuming and prone to errors. A Spectrum Control Butler matrix eliminates the need for these adjustments, ensuring that testing is both faster and more efficient, while also providing consistent, high-quality results. This ease of use and reliability set this product apart from others in the market.

What are the key features/specifications of the Butler Matrix family?
- In very simple terms the Butler distributes each input to all outputs providing equal power and progressive phase shift.
- Combining a Butler + Programmable Attenuator creates a simple conducted test environment that is broadband and bi-directional.
- Key component of a MIMO channel-emulator, providing ideal signal for maximum throughput measurements
- Transfers signals reciprocally from any input to all outputs with high phase accuracy, amplitude balance and high port-port isolation
- Wi-Fi Butler Matrix from a family of 4, 8 and 16 channel units
- Covers 0.5–7.25 GHz, with an excellent Channel Condition Number
What are common markets/applications?
SMPS connector applications include, but are not limited to:
- WiFi, Cellular and any RF/Microwave system that uses MIMO
- Test scenarios such as
- Engineering conducted channel emulation
- Production line testing
- System regression testing (firmware/software version changes, new RF hardware such as access points/BTS or terminal)
