RF modulator. An RF modulator (or radio frequency modulator) is an electronic device whose input is a baseband signal which is used to modulate a radio frequency source.
The RF part of the electromagnetic spectrum is generally defined as that part of the spectrum where electromagnetic waves have frequencies in the range of about 3 kilohertz (3 kHz) to 300 gigahertz (300 GHz).Probably the most important use for RF energy is in providing telecommunications services.or example, the unit volts per meter (V/m) is used to measure the strength of the electric field and the unit amperes per meter (A/m) is used to express the strength of the magnetic field. RF waves can be characterized by a wavelength and a frequency.
