Application Note

Load pull applications enhance the characterization and optimization of power amplifiers. Efficient amplifiers operate in the non-linear region near saturation, generating substantial harmonic power. To maximize power amplifier (PA) efficiency, these harmonic signals need impedance optimized for harmonic frequencies. This paper talks about the unique and compact turn key approach to harmonic load pull measurements when developing the latest amplifiers. Since advanced amplifier classes, such as classes F or J are commonly used in modern wireless communications systems, having the best efficiency and harmonic termination are important to keeping power consumption as lowas possible.
