PROBLEM TO BE SOLVED: To provide a signal power transmission circuit for transmitting its DC power output and its pulse signal output synchronously with an AC power frequency to a load such as an electronic circuit that increases the degree of freedom of a circuit design by reducing the number of patterns on a printed circuit board or the number of transmission lines between printed circuit boards, thereby eliminating the restriction of the layout of components on the board and the limitation of connection, reducing the cost, and improving the reliability. SOLUTION: A mixer circuit mixes the DC power output with the pulse signal synchronously with the AC power frequency and the mixed signal is transmitted through a single transmission line.
