Abstract :
A novel transmitter, which does not require the up-converter at the baseband stage, is presented. The main difference between proposed system and conventional one is the t use of an alias harmonic component as high-IF (intermediate frequency) signal. In this paper, each alias harmonic components are examined by EVM (error vector magnitude) and, the RF (radiofrequency) front-end using the 3rd order alias harmonic component at 180 MHz as IF is demonstrated. The EVM performance of RF output at 2150 MHz resulted in less than 4 % in the case of 200 ksps (symbol per second)
