HELP3E™ Dual-band Cellular & PCS CDMA 3.4 V Linear Power Amplifier Module

The AWC6325 is part of ANADIGICS’ 3rd generation of High-Efficiency-at- Low-Power (HELP3E™) family of power amplifiers, which deliver low quiescent currents and significantly greater efficiency through selectable bias modes for high, medium and low power operation. The AWC6325 is designed for use both with and without average power tracking (APT). APT can be used to optimize the Vcc level for the desired output power level and linearity, which greatly reduces the total current drawn from the battery. This feature, in conjunction with selectable operating modes, enables significant improvements in overall power added efficiency of the AWC6325 across the entire dynamic range of operating powers. APT requires use of an external variable voltage supply (DC-DC converter), which is used to provide the variable voltage to Vcc pad of the amplifier. A low-leakage shutdown mode increases standby time. This PA has built-in directional couplers for each band, with a common coupler output port CPL_OUT. The 3 mm x 5 mm x 0.9 mm surface mount package incorporates matching networks optimized for output power, efficiency and linearity in a 50 Ω system. The device is manufactured on an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness.
