SKY65131: WLAN Power Amplifier Module
Applications
Description
• IEEE802.11 b/g WLAN
The Skyworks SKY65131 is a Microwave Monolithic Integrated
Circuit (MMIC) Power Amplifier (PA) with superior output power,
linearity, and efficiency. These features make the SKY65131 ideal
for Wireless Local Area Network (WLAN) applications.
• ISM band transmitters
• WCS fixed wireless
• Wireless access nodes
Features
• Single 3.3 V supply
• Linear output power of +28 dBm for IEEE802.11b mask
• Linear output power of +26 dBm for IEEE802.11g mask
• High PAE of 38 percent
The device is fabricated using Skyworks high reliability Indium
Gallium Phosphide (InGaP) Heterojunction Bipolar Transistor (HBT)
technology. The device is internally matched and mounted in a
4 x 4 mm, Multi-Chip Module (MCM) Surface-Mounted
Technology (SMT) package, which allows for a highly
manufacturable low cost solution.
The device package and pinout are shown in Figure 1. A block
diagram of the SKY65131 is shown in Figure 2.

Technical Description
The SKY65131 PA contains all of the needed RF matching and DC
biasing circuits. The device also provides an output power
detector voltage and the ability to switch the PA on or off with a
simple control signal.
The SKY65131 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.,
WLANs).
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 SKY65131 is rated to Moisture Sensitivity Level 3 (MSL3) at
250 °C. It can be used for lead or lead-free soldering. Care must
be taken when attaching this product, whether it is done manually
or in a production solder reflow environment.
precaution should be taken to ensure that the part is not
subjected to temperatures exceeding 250 °C for more than
10 seconds.
For details on both attachment techniques, precautions, and
handling procedures recommended by Skyworks, please refer to
Skyworks Application Note, PCB Design and SMT
Assembly/Rework Guidelines for MCM-L Packages, document
number 101752. Additional information on standard SMT reflow
profiles can also be found in the JEDEC Standard J-STD-020.
Production quantities of this product are shipped in a standard
tape and reel format. For packaging details, refer to the Skyworks
Application Note, Tape and Reel, document number 101568.
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions are
described in Table 1. The absolute maximum ratings of the
SKY65131 are provided in Table 2. Electrical specifications are
provided in Table 3.
Typical performance characteristics are shown in Figures 3
through 9. A schematic diagram of the SKY65131 Evaluation
Board is shown in Figure 10. Package dimensions for the
SKY65131 16-pin MCM are shown in Figure 14, and tape and reel
dimensions are shown in Figure 15.
If the part is attached in a reflow oven, the temperature ramp rate
should not exceed 5 °C per second. Maximum temperature
should not exceed 250 °C. If the part is manually attached,
