Claim:
1. A millimeter-wave modulation apparatus, comprising: a plurality of transmitter units; and a modulation part, which carries out a modulation of a constant envelope attribute, and to which a first local oscillation signal is fixed according to a rate of input data; wherein each of the plurality of transmitter units comprises: wherein the plurality of transmitter units are connected to the modulation part via a switching device; wherein the switching device comprises: wherein the modulation part is configured to carry out a Minimum Shift Keying (MSK) modulation, and an MSK modulated waveform of the modulation part is represented by the following equation: wherein, B(t) represents 1 when AI(t) is the same as AQ(t), or represents −1 when AI(t) is different from AQ(t), and θ(t) represents 0 when AI(t) is 1, or represents π in the remaining cases except therefor.
