Historically, limited CW power was available in the millimeterwave frequency range, especially in the higher frequency bands, Ka-band and above. Therefore, power handling was not a major concern for most customers, except in the case of certain dedicated high-power applications or programs in which special attention was required. As semiconductor advancement and applications of such increased in scope, technology such as the Gallium Nitride devices (GaN) enables the expansion of 5G, IoT, small satellite and many other commercial, aerospace and military systems. But due to this, the specification for higher power handling capacity is required for even high frequency devices.
