CAUTION:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

Evaluation Board Description
The SKY66110-11 Evaluation Board is used to test the
performance of the SKY66110-11 front-end module. The board is
optimized for evaluation, experimentation, and investigation with
an 802.15.4 signal source. The design and layout can be quickly
and easily transferred into a production design.
An Evaluation Board schematic diagram is provided in Figure 3. A
reference design schematic is provided in Figure 4. Table 9
provides the Bill of Materials (BOM) list for Evaluation Board
components. A photograph of the Evaluation Board is shown in
Figure 5.
Evaluation Board Setup Procedure
Connect Supply
Package Dimensions
The PCB layout footprint for the SKY66110-11 is provided in
Figure 6. Typical part markings are shown in Figure 7. Package
dimensions are shown in Figure 8, and tape and reel dimensions
are provided in Figure 9.
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 SKY66110-11 is rated to Moisture Sensitivity Level 3 (MSL3)
at 260
C.
It can be used for lead or lead-free soldering. For
additional information, refer to the 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.
1. Connect J1 and J4 to 50
instruments. Terminate all unused
ports (if applicable) with 50
.
2. Connect the supply ground to Pins 1, 4, and 6 of J2.
3. Connect 3.3 V to pin 7 of J2.
4. Connect 1.8 V to one of the logic pins (pin 3 or pin 5) on J2 to
select RX or TX mode. Connect the other logic pin to ground.
Refer to Table 8 for mode control settings.
Measure Performance
TX
Monitor the 2.4
GHz
amplifier performance by applying an RF
signal to connector J4 (TR) and verify the output power on
connector J1 (ANT).
RX
Monitor the 2.4
GHz
switch performance by applying an RF signal
to connector J1 (ANT) and verify the output signal on connector
J4 (TR).
CAUTION:
Care should be taken not to overdrive the switch by
applying too much RF on the input to the device. A
starting input power of −20 dBm is suitable.
