• Manufacturer: Skyworks Solutions, Inc.

PRELIMINARY DATA SHEET • SKY65170-11 0.5 W, HIGH POWER PA
Technical Description
The SKY65170-11 PA contains all of the needed RF matching and
DC biasing circuits. The device is a two-stage, HBT InGaP device
optimized for high linearity and power efficiency. These features
make the device suitable for wideband digital applications, where
PA linearity and power consumption are of critical importance
(e.g., femtocell and infrastructure applications).
The device has been characterized with a standard CDMA2000
modulated signal. Under these stringent test conditions, the
device exhibits excellent spectral purity and power efficiency.
