Claims

[Scope of utility model registration request]

In an RF converter configured to distribute a carrier for amplitude modulation of a video signal sent from a carrier oscillation circuit to an amplitude modulation circuit for a video signal in the middle of the transmission path and supply it to a mixer circuit for a frequency-modulated audio signal, An RF converter in which a buffer circuit is provided between a carrier distribution location and the video signal amplitude modulation circuit to prevent audio signals and video signals from leaking into each other via the distribution location.
