Principle of outdoor base station signal amplification

How does a power amplifier affect a wireless base station?

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.

Why is a base station power amplifier important?

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.

How does a base station work?

Base stations typically have a transceiver, capable of sending and receiving wireless signals; Otherwise if they only send the trailer it will be considered a transmitter or broadcast point only. The base station will have one or more RF antennas installed to transmit and receive RF signals from other devices.

How does RF affect base station power consumption?

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.
