Array antenna is an adaptive design. From small form factor to large-scale planar, array antennas are widely used in mobile phones, 5G O-RAN FR2 RU, SATCOM, defense systems, and other applications. The high directivity of the array antenna is a key feature for compensating fading of mmWave communication signals. TMYTEK’s cutting-edge beamformer testbed provides multi-channel PA, LNA, Tx/Rx switch, and phase shifter, with a super intuitive GUI. This solution offers a ready-to-use array antenna verification platform for mmWave communication frontend system developers.
Moreover, the solution is structured for designing and validating the array antenna by integrating test fixtures. It is also designed to be integrated with a turntable, rotator and other measurement aids in test chambers.
The solution testbed is composed of two separable components:
1. AAkit - 4x4 high-performance array antenna reference design
2. PhiA box - well-calibrated multi-channel gain and phase controller
Antenna designers can replace the AAkit with their antenna array to perform tests and verifications without setting up extra frontend equipment.
Benefitted by BBox’s 16 independent RF-channels, it empowers users with the capability of multi-channel phase and amplitude control to fulfill mmWave phased array antenna testing requirements.

The key aspect of TMYTEK’s solution is its test repeatability and reproducibility. The solution also incorporates a chamber-optimized fixture that is designed to be able to integrate with chamber turntable and rotator for 2D/3D pattern scanning, as well as for rapid and stable measurements of antenna characteristics.
And benefited by the multi-channel testbed, the chamber can be upgraded with existing equipment from a single RF port expanded up to 16 individual channels with phase control, especially for mmWave array antenna testing.
The independent antenna channel for individual on/off for passive array antenna test; and multiple channel gain and phase control for active beam pattern verification.
The LabVIEW, MATLAB, Python, C#, and C++ are open-sourced APIs and can be integrated into your analysis system.
