Abstract
A wireless device that performs transmission of multiple wireless channels arranged within the used wireless frequency band at prescribed frequency intervals. Multiple wireless channels are divided into two systems, odd-numbered and even-numbered with gaps of one, or into two or more systems with gaps of two or more. Included are transmission amplifiers that transmit in common for each system, multiple band elimination filters connected in cascades to reduce the adjacent-channel leakage power in each system, and circulators that compose the transmission signals of each system. Transmission is done from an antenna via a transmission-reception signal splitter.
