In wireless base stations, the power amplifier (PA) dominates signal-chain performance in terms of power dissipation, linearity, efficiency, and cost. Monitoring and controlling the performance of a base station’s PA makes it possible to maximize the output power while achieving optimum linearity and efficiency.
The proliferating frequency bands and modulation schemes of modern cellular networks make it increasingly important that base-station power amplifiers offer the right combination of output power, efficiency and multi-band support – at both peak and average power levels. PAs are the main energy consumers in modern base stations.
Mobile communication systems have come to have high speed and capacity, leading to increased power consumption of base stations. The RF portion accounts for most of the base station power consumption, which means that reducing the power consumed by the RF portion is important for reducing the base station power consumption.
Increased speed and capacity leads to increased power consumption at base stations. Therefore, to reduce environmental impact and operational costs, it is necessary to reduce power consumption of the radio frequency (RF) portion, which accounts for most of the electric power consumed.
