ANADIGICS announces two multi mode, multi-band PAs. The AWT6223 combines IMT-band WCDMA operation with quad-band polar EDGE functionality. The AWT6225 integrates an IMT-band WCDMA PA with quad-band GSM/GPRS capabilities. The PAs utilize the company’s HELP2™ technology to reduce WCDMA average power consumption.
