The AWC6312R meets the increasing demands for higher efficiency and smaller footprint in CDMA 1X handsets. The AWC6312R uses ANADIGICS' exclusive InGaP-PlusTM technology, which combines HBT and pHEMT devices on the same die, to enable state-of-the-art reliability, temperature stability, and ruggedness. The AWC6312R is part of ANADIGICS' High-Efficiency-at-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 AWC6312R 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.
