Figure 2. SKY65135 Block Diagram
The SKY65135 PA contains all of the needed RF matching and DC
biasing circuits. The device also provides an output power
The SKY65135 is a three-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.,
The device has been characterized with the highest specified data
rates for 802.11b (11 Mbps) and 802.11g (54 Mbps). Under these
stringent test conditions, the device exhibits excellent spectral
purity and power efficiency.
Package and Handling Information
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed before shipping. Instructions on the
shipping container label regarding exposure to moisture after the
container seal is broken must be followed. Otherwise, problems
related to moisture absorption may occur when the part is
subjected to high temperature during solder assembly.
The SKY65135 is rated to Moisture Sensitivity Level 3 (MSL3) at
250 °C. It can be used for lead or lead-free soldering. For
additional information, refer to Skyworks Application Note, PCB
Design and SMT Assembly/Rework Guidelines for MCM-L
Packages, document number 101752.
Care must be taken when attaching this product, whether it is
