ALT6725 HELP3ETM Dual-band Cellular & PCS LTE 3.4 V Linear Power Amplifier Module PRELIMINARY DATA SHEET - Rev 1.0 FEATURES 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 ALT6725 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. • InGaP HBT Technology • High Efficiency: • 35 % @ POUT = +27.5 dBm • 16 % @ POUT = +15 dBm • 8 % @ POUT = +9 dBm • Low Quiescent Current: 4 mA • Internal Voltage Regulation • Built-in Directional Coupler • Common VMODE Control Line • Suitable for SMPS and average power tracking systems with variable supply voltages • APT can reduce TS.09 average power consumption more than 25% • Reduced External Component Count • Thin Package: 0.9 mm • RoHS Compliant Package, 260 oC MSL-3 APPLICATIONS • Dual-band Wireless Handsets and Data Devices for LTE/CDMA/EVDO networks: • UMTS Band 5, 6, 18, 19, & 26 VEN_CELL 1 14 GND Bias Control Voltage Regulation • UMTS Band 2 & 25 • Cellular BC 0 and 10 RFIN_CELL 2 CPL • PCS BC 1 and 14 PRODUCT DESCRIPTION VMODE1 3 ALT6725 addresses the demand for increased integration in dual-band handsets for LTE networks. The small footprint 3 mm x 5 mm x 0.9 mm surface mount RoHS compliant package contains independent RF PA paths to ensure optimal performance in both frequency bands in less board area than two single band PAs. The package pinout was chosen to enable handset manufacturers to independently provide bias to both power amplifiers and simplify control with common mode pins. The ALT6725 is part of ANADIGICS’ 3rd generation of High-Efficiency-atLow-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.

Shutdown Mode The power amplifier may be placed in a shutdown mode by applying logic low levels (see Operating Ranges table) to the VENABLE and VMODE pads. Bias Modes The power amplifier may be placed in Low, Medium, or High Bias modes by applying the appropriate logic level (see Operating Ranges table) to the VMODE pin. The Bias Control table lists the recommended modes of operation for various applications.
