The AWT6308R meets the increasing demands for higher efficiency and smaller footprint in CDMA 1X handsets. The package pinout was chosen to enable handset manufacturers to switch from a 4 mm x 4 mm PA module with few layout changes while reducing board area requirements by 44%. The AWT6308R uses ANADIGICS' exclusive InGaPPlusTM technology, which combines HBT and pHEMT devices on the same die, to enable state-of-the-art reliability, temperature stability, and ruggedness. The AWT6308R is part of ANADIGICS' High-Efficiencyat-Low-Power (HELPTM) 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 AWT6308R 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 voltage regulation components. The 3 mm x 3 mm x 1 mm surface mount package incorporates matching networks optimized for output power, efficiency, and linearity in a 50 system.
