Millimeter-wave Antenna Coupler

1. What are the FA-290, FA-291, FA-430 and FA-431 used for?

The Morita-Tech FA-290, FA-291, FA-430 and FA-431 are used for millimeter-wave wireless communication testing and OTA measurement. They are designed for 5G mobile communication systems and help engineers evaluate high-frequency wireless devices in a controlled RF test environment.

2. What frequency ranges are available?

The FA-290 and FA-291 support 24 GHz to 29.5 GHz, while the FA-430 and FA-431 support 24 GHz to 43.5 GHz. These frequency ranges make the couplers suitable for millimeter-wave 5G evaluation and high-frequency RF testing.

3. Why is close contact with the measurement target important?

Close contact with the measurement target helps improve coupling characteristics and supports more stable measurement conditions. It can also help reduce VSWR disturbance during total reflection, which is important for accurate millimeter-wave communication evaluation.

4. How can these antenna couplers support OTA measurement?

These millimeter-wave antenna couplers support OTA measurement by providing a compact and controlled coupling method for high-frequency wireless testing. They help engineers evaluate antenna performance, communication characteristics and EVM behavior in 5G millimeter-wave applications.

5. What are the main benefits of these antenna couplers?

The main benefits are millimeter-wave frequency support, optimized coupling performance, reduced VSWR disturbance, stable EVM measurement support, and model options for different test setups. The series includes both large and small models, allowing engineers to select a suitable coupler depending on the device size and measurement environment.
