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.
