Abstract
A modulation circuit that can improve an on/off ratio or increase short pulses, and a wireless communication apparatus are provided. The modulation circuit includes a first transistor in which a first signal is input to a gate terminal; a second transistor that is cascode-connected to the first transistor by connecting a source terminal to a drain terminal of the first transistor, that receives an input of a second signal having a frequency lower than the first signal at a gate terminal, and that modulates the second signal by the first signal and outputs the modulated second signal; and a switch circuit that is formed on the output side of the second transistor. The switch circuit is turned on in synch with a switching of the second transistor to an off state, and turned off in synch with a switching of the second transistor to an on state.
