Signal transmission device, electronic device, and signal transmission method

#The present disclosure relates to a signal transmission device, an electronic device, and a signal transmission method. More specifically, the present disclosure relates to a technique of transmitting a control signal when performing signal processing using the control signal.

#In electronic devices, signal processing is sometimes performed based on a control signal. In some cases, signal processing is performed using a reference signal. In such a case, how to provide (supply) the control signal or the reference signal to circuit functional units which require the signal becomes an issue.

#JP-A-2003-244016 discloses a method in which a local oscillation signal of a millimeter band is transmitted as a reference signal to respective chips, and the respective chips transmit and receive an intermediate frequency-band signal by up-converting the frequency to the millimeter band using the common local oscillation signal received by the respective chips.

#FIG. 1 is a diagram illustrating a basic configuration example (first example) of a signal transmission device according to the present embodiment.

#FIG. 2 is a diagram illustrating a basic configuration example (second example) of the signal transmission device according to the present embodiment.

#FIGS. 3A to 3C are diagrams illustrating the configuration of the combination of a signal transmission device and a control signal transmitting device.

#The exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings. When a distinction is made between respective functional elements, such elements will be denoted by reference numerals such as a letter or “_@” (@ is a number). Where no particular distinction is made therebetween for description, such reference numerals will be omitted. The same holds true for the drawings.

#The description will be given in the following order.
