SKY65135: WLAN Power Amplifier
Applications
Description
• IEEE802.11 b/g WLAN
Skyworks SKY65135 is a Microwave Monolithic Integrated Circuit
(MMIC) Power Amplifier (PA) with superior output power, linearity,
and efficiency. These features make the SKY65135 ideal for
Wireless Local Area Network (WLAN) applications.
• ISM band
• WCS fixed wireless
• Wireless access nodes
Features
• Linear output power of +31 dBm for IEEE802.11b mask
• Linear output power of +30 dBm for IEEE802.11g mask
• Three percent EVM at POUT >+27 dBm
• High gain of 33 dB
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
20-pin, 6 x 6 mm Multi-Chip Module (MCM) Surface-Mounted
Technology (SMT) package, which allows for a highly
manufacturable low cost solution.
The device package and pinout for the 20-pin MCM are shown in
Figure 1. A block diagram of the SKY65135 is shown in Figure 2.

Technical Description
The SKY65135 PA contains all of the needed RF matching and DC
biasing circuits. The device also provides an output power
detector voltage.
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.,
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 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
done manually or in a production solder reflow environment.
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
SKY65135 are provided in Table 2. Electrical specifications are
provided in Table 3.
Typical performance characteristics are shown in Figures 3
through 11. Figure 12 provides a typical evaluation board
schematic. An assembly drawing for the Evaluation Board is
shown in Figure 13 and the layer detail is provided in Figure 14.
The layer detail physical characteristics are noted in Figure 15.
The phone board layout footprint for the SKY65135 is shown in
Figure 16. Package dimensions for the 20-pin MCM are shown in
Figure 17, and tape and reel dimensions are provided in
Figure 18.
Electrostatic Discharge (ESD) Sensitivity
The SKY65135 is a static-sensitive electronic device. Do not
operate or store near strong electrostatic fields. Take proper ESD
precautions.
