Frequency-Tunable Capability

  • Paulo Augusto Dal Fabbro
  • Maher Kayal
Part of the Analog Circuits and Signal Processing book series (ACSP)


This chapter introduces the concept of frequency-tunable capability applied to RF power amplifiers, making some definitions and establishing the metrics for the evaluation of the design, which is the subject of Chap. 6. It also surveys the main techniques found in the literature that could be used in the design of the frequency-tunable amplifier. The advantages and drawbacks of each technique are discussed and the choice of the coupled-inductors technique is explained, together with the description of its use to implement a novel tunable output impedance matching network to be employed in multiband RF power amplifiers.
