ABSTRACT:
An RF modulator is characterized by a gain adjusting circuit for gain adjustment incorporated with an RF amplifier for amplifying a carrier wave provided from a carrier oscillator and applying the same to a video signal modulator and to an audio signal mixer so that the gain of the RF amplifier is adjustable so as to adjust a difference in level of the carrier wave provided differently depending upon a resonance element being connected to the carrier oscillator.
