microwave region

microwave region

Commonly, that region of the radio spectrum between approximately 1000 MHz and 300,000 MHz. Corresponding wavelengths are 30 cm to 1 mm. The limits of the microwave region are not clearly defined, but in general they are considered to be the region in which the radar operates. See electromagnetic spectrum.
