While the target application dictates the RF requirements, efficiency and cost are the main differentiating factors for RF power amplifier solutions. Various techniques can be used to improve efficiency, e.g. technologies such as GaN with increased energy density. Envelope tracking and digital predistortion (DPD) extend the linear range of amplifiers. Classic multipath structures such as Doherty and outphasing amplifiers are experiencing a comeback in current designs.
Webinar
RF amplifier efficiency
In this webinar, we discuss how fundamental techniques such as load modulation, supply modulation, and waveform engineering can be optimaly mixed to define the maximally efficient amplifier. Learn how you can get close to the theoretical efficiency limit while leveraging the techniques, with a suitable scheme.
Measurement aided Doherty amplifier
Doherty amplifier architecture enables RF PA designers to maximize efficiency, power, bandwidth and yield without compromising linearizability. Whether it is for 5G, SatCom or any other application demanding high performance and reproducibility, the challenges remain the same: how can you be sure that you are getting the maximum possible performance from the design and how can you evaluate its sensitivities and variations for series production?
