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.

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. The ALT6725

APPLICATION INFORMATION
To ensure proper performance, refer to all related
Application Notes on the ANADIGICS web site: http://
www.anadigics.com along with Figure 3, which shows
the recommended ON/OFF timing sequence for RFIN,
control voltages, and supply voltages.
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.

PCB BOARD Design GuidELINES
Refer to Figure 7 for the recommended PCB metal
design, soldermask design, and stencil print patterns
when assembling with ANADIGICS modules [5].
It is important to note that the PCB metal design is
dependent upon several factors: the electrical and
thermal performance requirements of the product,
and the PCB-to-device interconnect pattern. The
PCB metal design recommendations primarily deal
with te PCB-to-device interconnection. Specific
board-level electrical and thermal performance requirements will be dictated by the physical geometry
of the specific application and are the responsibility
of the end product manufacturer.
