Abstract
A digital intermediate frequency transmitter for a wireless communication is disclosed. In accordance with the present invention, an improvement of a modulation quality such as an EVM, a linearity and a power consumption is possible, and a main characteristic of a wireless communication transmitter may be embodied at a low cost through an integration such that a high frequency 90° phase shifter, a voltage controlled oscillator having a 2× frequency or higher and a high frequency I/Q local oscillated signals are not required and a side-band signal may be effectively removed.
