Abstract:
1. A millimeter wave band transmitter comprising: a frequency arranging circuit coupling a plurality of input modulation signal waves while frequency-converting at least one of said plurality of input modulation signal waves from a frequency position lower than a frequency position of at least one other of said plurality of input modulation signal waves to a frequency position adjacent to and higher than the frequency position of the at least one other of said plurality of input modulation signal waves along a frequency axis in order to generate a multiplex signal wave having respective frequency bands of said plurality of input modulation signal waves arranged on the frequency axis independent of each other, a frequency up-converter up-converting said multiplex signal wave to a millimeter wave band to generate a millimeter wave band multiplex signal wave, and a transmission circuit transmitting said millimeter wave band multiplex signal wave.
