The AWT6307R 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
AWT6307R uses ANADIGICS’ exclusive InGaPPlus™ technology, which combines HBT and pHEMT
devices on the same die, to enable stateof-the-art reliability, temperature stability, and ruggedness.
The AWT6307R 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 AWT6307 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 Ω system.
