RF Micro Devices RF323x power platform

RF Micro Devices has expanded its product range to include a complete power platform for entry-level 3G handsets.

The RF323x power platform comprises the RF323x and RF72xx product families and provides handset manufacturers a reference design for implementing multi-region multimode 3G handset platforms.

The platform features the PowerStar-based RF323x 2G transmit module with pin-compatible options supporting either one or two bands of WCDMA. The pin-compatible WCDMA PAs are available in two product family options.

The first option, the RF724x family of WCDMA power amplifiers, addresses all major frequency bands and delivers peak efficiency and DG.09 as low as 13 mA through the use of multi-bias control.

The second option, the RF722x family of WCDMA power amplifiers, also addresses all major frequency bands and is optimised for chipsets using three-mode control schemes.
