RF Micro Devices has started volume production of its RF720x WCDMA/HSPA+ power amplifiers (PAs).
The RF720x family is optimised for smartphone handset reference designs from Qualcomm and other suppliers.
The chips support all major WCDMA/HSPA+ bands and band combinations.
According to Eric Creviston, president of RFMD's Cellular Products Group (CPG), there is significant smartphone design activity taking place particularly in Korea, China and Taiwan.
“We are currently forecasting double-digit growth in 3G in calendar 2010, based upon existing customer design activity,” said Creviston.
These are mode-specific/band-specific PAs covering 3G frequencies.
Each RF720x PA digitally controlled power management in both 3G voice and 3G data operation.
