What is a power supply module?

A Power Supply Module is used in a base station/repeater with a Power Amplifier Module (e.g. rated at 100 W output power). The model generates the +5.1 V, +14.2 V, and +28.6 V operating voltages for the base station/ repeater modules. These modules have power factor correction and include a connection for battery backup.

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.

How can a base station reduce energy consumption?

Significant efforts are being made to reduce the overall energy consumption of base stations to lessen their impact on the environment. Electrical energy is the principal source of everyday operating costs in a base station, and the PA can be responsible for more than half of the power dissipation.

What is a 3G base station converter?

In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.

Why is power efficiency important in a base station?

Electrical energy is the principal source of everyday operating costs in a base station, and the PA can be responsible for more than half of the power dissipation. Thus, optimizing the PA’s power efficiency improves operational performance, and provides environmental and financial benefits.

What voltage does a DSL power system supply?

The DSL power system may supply both higher voltage analog line drivers and amplifiers (typ. +/-12V) and several low voltage supplies required by the digital ASIC (+5V, +3.3V, +1.8V, +1.5V).
