3. TECHNICAL BRIEF
AWT6321 is part of ANADIGICS' high-Efficiency-at-Low-Power (HELP™) family of CDMA
power amplifiers, which deliver low quiescent currents and significantly greater efficiency
without a costly external DAC or DC-DC converter. Through selectable bias modes, the
AWT6321 achieves optimal efficiency across different output power levels, specifically at low-
and mid-range power levels where the PA typically operates, thereby dramatically increasing
handset talk-time and standby-time. Its built-in voltage regulator eliminates the need for
external switches. The 3 mm x 5 mm x 1 mm surface mount package incorporates matching
networks optimized for output power, efficiency and linearity in a 50 Ω system.
