30GHz-300GHz millimeter wave RF/OTA/PD test
1. Introduction of millimeter wave
Millimeter wave (mmwave) refers to electromagnetic waves with wavelengths between super high frequency (SHF) and high frequency (EHF). The wavelength range of millimeter waves is approximately between 1 and 10 millimeters, and the corresponding frequency range is 30 to 300 GHz. Mainly used in weather radar, space communication, radio astronomy and so on.
2. Common millimeter wave products
