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.

PRODUCT DESCRIPTION
The ALT6702 HELP4^TM PA is a 4th generation
HELP^TM product for LTE and WCDMA devices
operating in UMTS PCS (Band 2) and for CDMA
devices operating in Band Class 1 and Band Class
14. 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.
