What Is RF Microwave Radiation?
The use of Radio Frequency "RF" Wave technology plays an integral part in our daily lives. As AC Electric fields and AC Magnetic fields approach higher frequencies, the fields become airborne and in this condition become Radio Waves. Microwaves are simply higher frequency radio waves. RF waves are used to convey information from one place to another through the air. They are used in mobile communication, radio and television broadcasts, radar, satellite navigation, homeland security and are a significant part of what we recognize today as an international communication infrastructure. These high energy, airborne waves, are capable of traveling miles. RF waves are considered high frequency electromagnetic radiation (10 MHz -300 GHz). Power density readings in microwatts per square meter are often used to express the magnitude of the signals. A spectrum analyzer is used to identify the specific frequency of a signal. Broadband RF meters are used to measure multiple sources in larger frequency bands.
