SIGNAL PROCESSING APPARATUS

摘要

Provided is a signal processing apparatus. The signal processing apparatus comprises an image rejection mixer, an oscillator, a switching unit, and a transmission signal processing unit and a reception signal processing unit. The image rejection mixer up-converts transmission signals and down-converts reception signals. The oscillator provides oscillation frequency signals to the image rejection mixer, and the switching unit is connected to the image rejection mixer to switch a transmission path and a reception path to selectively pass transmission signals and reception signals. The transmission signal processing unit and the reception signal processing unit are connected to the switching unit to process transmission signals and reception signals, respectively.
