    • PROBLEM TO BE SOLVED: To improve ON/OFF operations on switching operations, and also to improve the ON/OFF ratio of output electric power as the entire pulse modulation circuit. SOLUTION: The pulse modulation circuit uses a harmonic mixer 1 which inputs an LO signal and a DC pulse signal and combines the second harmonic of the LO signal with the DC pulse signal to output an RF pulse signal. An SPST switch 2 is connected in series at the front stage of the harmonic mixer 1 and is subjected to switching operations by the DC pulse signal simultaneously with the harmonic mixer 1. The ON/OFF ratio of the harmonic mixer 1 itself is thereby added to the ON/OFF ratio of the SPST switch 2 to improve both the ON/OFF operations on switching operations and the ON/OFF ratio of the output electric power as the entire pulse modulation circuit.
