Power amplifiers for mobiles
This HELP4 WCDMA family includes the AWT6621, AWT6622, AWT6624, AWT6625 and AWT6628 PAs, each designed for specific wireless bands.
The fourth generation of HELP (High-Efficiency-at-Low-Power) PAs are ideal for a broad spectrum of mobile device applications as they deliver maximum efficiency at various power levels, including a 50-percent reduction in current consumption where mobile devices operate most frequently. They also enable up to 75-percent longer battery life, resulting in significantly longer talk time in handsets.
With the proliferation of technologies like HSPA+, which improve wireless network performance, the global 3G WCDMA market remains the most pervasive 3G system globally. According to the GSA (Global mobile Suppliers Association), 3G/WCDMA is the leading 3G system globally with commercial service in 135 countries. 97% of WCDMA operators have commercially launched HSPA. Yet mobile broadband downlink and uplink speeds using HSPA are evolving. The Network Update reports on 80 operator commitments to deploy HSPA+ including 41 commercial systems launched in 26 countries.
Key Product Facts and Highlights:
