5g micro base station rated voltage

What is a small cell in 5G?

Small cells are a new part of the 5G platform that increase network capacity and speed, while also having a lower deployment cost than macrocells. The compact size of a small cell requires that all components – especially power converters – provide high eficiency, better thermals and eventually the best power density possible.

How much DC does a 5G system need?

For example, a 27 dBm output power with a 20% efficient PA would require about 2.5 W DC at the DC supply line (typically, a 5 V DC supply for these low power levels). Keep in mind that 5G systems are typically operating in time division duplexing (TDD) mode, which implies that ~70% of the time, transmit is operating.

How much peak power do you need for a 5G signal?

If building, for example, a 24 dBm average transmit chain targeting a 5G signal with 10 dB of PAPR, you need to dimension for (24+10=) 34 dB peak power. This peak power is the level at which the PA needs to transmit without significant impact on signal quality.

How does a small cell base station affect a smartphone's battery life?

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.
