- Nowadays switching power supplies are commonly used because they offer better efficiency and smaller size compared to a linear power supply, because high switching frequency allows for smaller transformers. One place to find a SMPS (switching mode power supply) is a phone charger. Switching power supplies cause high frequency noise on switching transients. The noise on the output is filtered in various ways but savings may be considered on the output filter (extra inductors and capacitors = extra costs), which means the output will have some amount of noise left getting to the device via the USB cable. Estimate the frequency where the phone charger starts to act as an antenna when the USB cable length is 1.9 meters. Submit your answer in MHz without the unit, rounded to one decimal place.
