Abstract: An integrated circuit includes input circuitry for receiving a radio frequency digital signal, output circuitry capable of delivering a radio frequency analog signal, and a processing stage coupled between the input circuitry and the output circuitry and including several processing channels in parallel. Each processing channel may include a voltage switching block the input of which is coupled to the input circuitry and a transmission line substantially of the quarter-wave type at the frequency of the radio frequency analog signal coupled in series between the output of the voltage switching block and the output circuitry.

Abstract: Integrated circuit, incorporating an electronic device (PA) comprising input means (BE) for receiving a radiofrequency digital signal (SCH), output means (BS) capable of delivering a radiofrequency analogue signal (SARF), and a processing stage coupled between the input means and the output means and comprising several processing channels (VTi) in parallel, each processing channel (VTi) including a voltage switching block (BLCi) the input of which is coupled to the input means and a transmission line (LTi) substantially of the quarter-wave type at the frequency of the radiofrequency analogue signal coupled in series between the output of the voltage switching block and the said output means.
