Abstract
A wireless communication transceiver and a mode switch device thereof. The transceiver includes: a first band transmission path; a first band reception path; a second band transmission path; a second band reception path; a path switch and a control unit. In a dual band time division duplexing mode, the control unit controls the path switch so that the path switch connects a received radio frequency signal from an antenna to the first band reception path, and connects a transmitted radio frequency signal from the second band transmission path to the antenna in an odd cycle or an even cycle; and controls the path switch so that the path switch connects a received radio frequency signal from the antenna to the second band reception path, and connects a transmitted radio frequency signal from the first band transmission path to the antenna in another odd cycle or another even cycle.
