The ETH-MMW-1000 from AVX Corporation is a compact, cost-effective, extremely accurate, and easily adaptable portable solution for testing 5G antennas and other devices at millimeter wave (mmWave) frequencies from 18 to 110 GHz.
The ETH-MMW-1000 Millimeter Measurement System is a fully anechoic aluminium enclosure on a mobile chassis with steerable lifting wheels that enable quick and easy relocation and provide optimal stability during measurements. It is equipped with sliding doors for easy access to the center of the system and the device under test (DUT), as well as a distributed axis positioning system that is comprised of a height-adjustable, PVC, azimuth mast rotator that rotates the DUT about the Phi axis and a Theta ring positioner that elevates the measurement horns around the DUT.
This modular, mobile, far-field measurement solution offers a shielded environment to ensure stable measurement results over a wide frequency range, requires no up or down frequency conversion to ensure excellent phase stability and accuracy, and is easy to install and relocate within both new and existing laboratory and production environments.
The system has a dynamic range of up to 55 dBm and a peak gain accuracy of ± 0.9 dB. It takes up to 19 minutes to perform 10° sampling of 100 frequencies and up to 5.5 minutes to perform 22.5° sampling of 100 frequencies. It uses a far-field/spherical technology with oversampling to measure gain, directivity, efficiency, beamwidth, cross-polar discrimination, sidelobe levels, 3D radiation pattern, radiation pattern in any polarization, TRP, TIS, EIRP, EI, etc.
The ETH-MMW-1000 is a flexible turn-key solution suitable for all testing needs for mmWave system development & validation and has an integrated Gigahertz Control Unit, Measurement PC, and a Vector Network Analyzer, a Spectrum Analyzer, or a Radiocom Tester. It has a half-sphere support interface with a dedicated notch to position the device under test (DUT) in vertical/horizontal position and a height-adjustable PVC mast to center the DUT in the middle of the rotating ring.
The ETH-MMW-1000 requires an AC supply of 110-240 V and consumes 10-16 A of current. It measures 1560 x 2128 x 1236 mm.
