The most common method is to use multistage conversion: Table 1. Base station types. first the AC/DC or isolated PoE converter generating the intermediate bus voltage of 12 V or 5 V, and then a point-of-load converter to step down once more to the necessary voltage level.
Base station types. first the AC/DC or isolated PoE converter generating the intermediate bus voltage of 12 V or 5 V, and then a point-of-load converter to step down once more to the necessary voltage level. If the PoE architecture includes power-sourcing equipment (PSE), a 48-V power rail has to be stepped down to power the PSE controller.
When a mobile device is close to a small-cell base station, the power needed to transmit the signal is much lower compared to the power needed to transmit a signal from a cell tower far away, thus extending smartphone battery life.
In a small cell, the power requirements come from the analog front end (AFE), field-programmable gate array (FPGA) or application-specific integrated circuit (ASIC) that needs power. While every designer does it a little bit differently,
