Description
The SKY65943-11 is a front-end module (FEM) with an integrated
low-noise amplifier (LNA) and pre-filter and post-filter designed
for Global Navigation Satellite System (GNSS) receiver
applications. The device provides high gain, excellent out-of-band
rejection, and low noise figure. The pre-filter and post-filter
provide low in-band insertion loss and excellent rejection for the
cellular, PCS, and WLAN frequency bands. Output matching
components are embedded inside the device. Only one external
input matching inductor is required.
The SKY65943-11 is optimized to operate at 1559 to 1606 MHz,
which makes it ideal for GPS/GLONASS/Galileo/Compass/QZSS
radio receiver applications.
The SKY65943-11 uses surface-mount technology (SMT) in the
form of a 2.5 x 2.5 mm Multi-Chip Module (MCM) package, which
allows for a highly manufacturable and low-cost solution.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters
set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
ESD HANDLING: 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 when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.

Evaluation Board Description
The SKY65943-11 Evaluation Board is used to test the
performance of the SKY65943-11 LNA. An assembly drawing for
the Evaluation Board is shown in Figure 3. The Evaluation Board
schematic diagram is shown in Figure 4. Table 6 provides the Bill
of Materials (BOM) list for Evaluation Board components.
Package Dimensions
The PCB layout footprint for the SKY65943-11 is provided in
Figure 5. Typical part markings are shown in Figure 6. Package
dimensions are shown in Figure 7, and tape and reel dimensions
are provided in Figure 8.
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 SKY65943-11 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 & 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.
