Abstract
There is provided a RF-DAC that may include (i) a first PAM that includes a first group of first power amplifiers of different amplifications, (ii) a second PAM that includes a second group of second power amplifiers of different amplifications; (iii) a load that includes an output port and a transformer; (iv) power amplifiers control units, and a transformer control unit. During a cycle of operation (i) each one of the first and second PAMs is configured to receive one or more power amplifiers digital control signals and activate a single power amplifier per each of the first and second PAMS, (ii) the transformer control unit is configured to receive a transformer digital control signal and control a transformer parameter of the transformer, and (iii) the transformer is configured to receive a first PAM output signal and a second PAM output signal, and output a transformer output signal that reflects digital information represented by the one or more power amplifiers digital control signals and the transformer digital control signal.
