Radio frequency (RF) modulators are used for coupling an audio signal into an audio system via its radio tuner when an auxiliary input to the audio system is not available. In order to modulate the output of a radio frequency source, a modulator or attenuator is usually connected in series with the source. A typical radio frequency modulator may operate using frequency modulation at the lower end of the FM broadcast band. A reflective shunt diode modulator consists of a transmission line which is connected to ground at intervals by PIN diodes.
