| Popis: | The measurement and modeling of the dynamic power dissipation of a dual-input Chireix power amplifier driven by LTE modulated signals is reported to optimize its dynamic efficiency. Two memory cubic spline FIR and NARMA behavioral models are verified to accurately predict the measured instantaneous PA bias-current and power dissipation as a function of the PA RF output power. |
