Modern wireless communication systems have evolved to support increasing numbers of subscribers and provide higher data rate services within the limited frequency resources. As part of this evolution, many transmitted signals in the new standards, such as WCDMA, long term evolution (LTE), and worldwide interoperability for microwave access (WiMAX), now utilize a high peak-to-average power ratio (PAPR)...
In wireless communication systems, the radio-frequency (RF) power amplifier (PA) is one of the most critical components in the design of wireless transmitters. This is true whether one is interested in low-power portable devices transmitting hundreds of milliwatts, high-power cellular base stations transmitting tens of watts, TV transmitter pumping out hundreds of watts or other space-based and terrestrial...
