A digital / analog (D / A) converter 206 multiplies the sine wave approximation 300 to the frequency conversion on the input signal. Optimized coefficient values are chosen and is programmed on the basis of the control word that is generated during the clock cycle. A programming cycle for indicating the frequency of the sine wave approximately 300 gives provide the multiplied signal to the input signal so that the benefits of maintaining a normal switching mixer while reducing the effect of the odd harmonics at the output. Multiplication according to one embodiment of the D / A converter includes a plurality of a plurality of resistors (R1-R8), select resistors (R1-R8) in order to prevent the operation and behavior (in and out of operation) is connected to the amplifier 400 comprises a control word coming from the switching gate (G1-G8), the gate counter / controller 203 for controlling (G1-G8).
