Cutting RF power in W-CDMA phones News & Analysis 6/30/2004 Post a comment The spread-spectrum wireless communications standard, IS-95/3GPP, embodies stringent specifications for linearity and adjacent-channel power ratio (ACPR), says this Maxim engineer. The power amplifier does not operate continuously in voice mode. When the phone user isn't speaking, it runs at a half rate (50 percent of the time) or at a one-eighth rate, so there's no worry about the phone's heating during voice mode. But in data mode the PA runs continuously until the data transmission is complet
Power reduction remains top priority for 3G mobiles News & Analysis 6/30/2004 Post a comment Earlier this year, Vodafone chief executive officer Arun Sarin said that product quality deficiencies would slow the rollout of third-generation (3G) mobile phones. They are bulky, they get hot, and they don't have enough battery life," he said. Rob Keenan uses this as the kick-off point from an EE Times' article package on cell phone power managmenet. The big issue is in W-CDWA power consumption, he warns.
