This mmWave system is tailored for high-frequency over-the-air testing from 50 GHz up to 220 GHz. The bundle supports modular construction with 2, 3, or 4 chamber cubes to achieve different far-field distances, integrating CMT’s VNA, mmWave extenders, and a precise gimbal. The solution is portable, space-efficient, and ideal for mmWave antenna development in automotive radar, satellite communications, and advanced research.
