Patent ID: 7755524

Claim:
An electronic device comprising: a radiofrequency (RF) digital to analog conversion block comprising a block input to receive a digital signal, a block output to deliver an RF analog signal, at least one cell comprising a first input coupled to the block input, a second input to receive an RF transposition signal, a third input to receive a control signal having a frequency greater than a frequency of the RF transposition signal, each transition of the RF transposition signal occurring between two consecutive pulses of the control signal, a fourth input to receive a power control signal, a cell output coupled to said block output, transposition circuitry coupled to said first and second inputs and to generate a transposed digital signal, and conversion circuitry, controllable by the control signal and the power control signal, to receive the transposed digital signal and to perform a digital to analog conversion thereof to the RF analog signal to the block output.
