The application of wireless technology is widespread and our culture has an appetite to be un-wired. Cell phones, wireless data, GPS, digital radio and TV, and wireless peripherals are common applications of communication technology. In terms of energy consumption, which relates to battery size in mobile devices, and utility costs in infrastructure, the power efficiency of the radio frequency (RF) amplifier is very important. The RF amplifier circuitry consumes a large portion of the power in a wireless system, and improvements in amplifier efficiency have significant implications for the overall energy consumed in a wireless device.

无线技术的应用非常广泛，我们的文化也渴望脱离有线。移动电话、无线数据、全球定位系统、数字广播和电视以及无线外设是通信技术的常见应用。就能量消耗而言，这与移动设备的电池尺寸和基础设施的实用成本有关，射频放大器的功率效率非常重要。射频放大器电路在无线系统中消耗很大一部分功率，并且放大器效率的改进对无线设备中消耗的总能量具有重要意义。
