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.
This increase reduces the eficiency of the power amplifier (PA). Envelope tracking, or supply modulation, uses a dynamic power supply to vary the PA supply voltage in accordance with the time-varying envelope of the input signal so that the eficiency of the PA is maximized.
PA drain bias voltage modulation The signals in modern wireless communication systems have high peak-to-average power ratios (PAPR). Techniques such as average power tracking (APT) and envelope tracking (ET) increase the power efficiency of a PA in a base-station application, as depicted in Figure 1.
A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.
Modern communication systems demand high data capacity and high speed. The long-term evolution (LTE) standard for the fourth-generation (4G) and the fifth-generation (5G) wireless systems requires signals with higher PAPR compared with prior generations. This increase reduces the eficiency of the power amplifier (PA).
