Keeping the best audio quality in mobile phone by managing voltage drops created by 217 Hz transients
 
By Marie Maurel,
Audio Product Line Manager,
Dolphin Integration
Whatever the protocol used by a mobile phone, GSM or TDMA, RF transmitter switching creates the most notorious noise for the power supply. The RF power amplifier switches on and off at a rate of 217 Hz. At each of these events, a high current (up to 1.7A) is drawn from the power supply, creating a sudden voltage drop on the battery equivalent serial resistance (ESR) reaching up to 500 mV. more >>
