How will mmWave based 5G affect PA & PSU designs?Site-selection considerations also are driving changes to the PA and PSU designs. The higher the frequency, the shorter the signals travel, which means mmWave-based 5G will require a much higher density of small cells compared to 4G. Many 5G sites will also need to be close to street level, where people are.
How does a 5G base station reduce OPEX?This technique reduces opex by putting a base station into a “sleep mode,” with only the essentials remaining powered on. Pulse power leverages 5G base stations’ ability to analyze traffic loads. In 4G, radios are always on, even when traffic levels don’t warrant it, such as transmitting reference signals to detect users in the middle of the night.
Should a 5G power amplifier be combined with a power amplifier?For 5G, infrastructure OEMs are considering combining the radio, power amplifier and associated signal processing circuits with the passive antenna array in active antenna units (AAU). While AAUs improve performance and simplify installation, they also require the power supply to share a heatsink with the power amplifier for cooling.
Why does 5G cost more than 4G?This percentage will increase significantly with 5G because a gNodeB uses at least twice as much electricity as a 4G base station. The more operators spend on electricity, the more difficult it is to price their 5G services competitively and profitably.
Why is Infineon developing a 500-W 5G PSU?thermal resistance between the device and heatsink.This and other techniques, such as greater use of planar magnetics, have enabled Infineon to develop a prototype 500-W 5G PSU that delivers high efficiency in a dense, low-profi.
Why do we use a dual-boost topology in a 5G PSU?o implement each approach and the thermal behavior. For example, in our 500-W 5G PSU design, we have chosen a dual-boost topology using silicon MOSFETs, partly because this approach spreads the thermal losses due to switching across two devices, reducing the amount each h ats up and creating two lower-temperature hotspots.Below in Fig. 4
To understand how, consider the power amplifier (PA) and power supply unit (PSU) in the 5G New Radio (NR) gNodeB base station. In 2G, 3G and 4G, the PA and PSU were
