Abstract
- A power amplifier (PA) for multiband applications implemented with a tunable load modulation technique is presented. The broadband output matching can be done by load modulation implemented by modification of the characteristic impedance (ZC) of the tunable transmission line. The multiband PA delivered a gain of more than 10.5 dB, an adjacent-channel-leakage ratio of evolved UMTS terrestrial radio access adjacent channel leakage ratio (E-UTRA) lower than −30 dBc, and a power added efficiency of 28–31% at the output power of 26-dBm and the frequency range of 1.5–2.05 GHz with a 10-MHz 16QAM long-term evolution signal. © 2014 Wiley Periodicals, Inc.
