The ALT6720 HELP4 PA is a 4th generation HELP
product for LTE devices operating in E800 MHz Band
20. This PA incorporates ANADIGICS’ HELP4
TM
technology to deliver exceptional efficiency at low
power levels and low quiescent current without the
need for external voltage regulators or converters.
The device is manufactured using advanced InGaP-
Plus
TM
HBT technology offering state-of-the-art
reliability, temperature stability, and ruggedness.
Three selectable bias modes that optimize efficiency
for different output power levels and a shutdown
mode with low leakage current increase handset
talk and standby time. A “daisy chainable” directional
coupler is integrated in the module, thus eliminating
the need of an external coupler. The self-contained
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.
