RF power amplifier linearization techniques

Improving the non-linear behavior of RF power amplifiers

RF frontends need to support specific frequencies, gains and bandwidths. To meet these requirements and to optimize efficiency, the RF amplifier is often used close to compression, where the device behaves in a non-linear way. Dedicated linearization techniques such as digital predistortion (DPD) are used to precompensate these effects. Not all RF frontends allow similar linearization methods. Dedicated test and measurement solutions from Rohde & Schwarz help you with these RF power amplifier linearization techniques.

Investigate RF Power Amplifier Linearization Benefits in EDA

This application note is based on collaborative work between Cadence and Rohde & Schwarz.

The focus is on understanding as early as possible in the design process performance enhancements through linearization of non-linear devices, in our case the RF power amplifier (PA). In other words, what performance benefits can be reached with linearization techniques such as digital predistortion (DPD).

Iterative direct digital pre-distortion (DPD)

Many transmitters employ digital predistortion (DPD) to maintain signal quality. Implementing real-time DPD in a transmitter is a challenging task that often ends in power amplifier models that are specific to the transmitted signal.
