WebMar 21, 2024 · 1.2: RF and Microwave Engineering. An RF signal is a signal that is coherently generated, radiated by a transmit antenna, propagated through air or space, collected by a receive antenna, and then amplified and information extracted. An RF circuit operates at the same frequency as the RF signal that is transmitted or received. WebA microwave is a high- frequency radio wave. They are broadly defined as having a wavelength between 1 millimeter and 1 meter, or narrowly between 3 mm and 300 mm. Microwaves have many uses including radar, radio astronomy, and to heat food in a microwave oven.
