Description
The SKY65601-477LF is a Microwave Monolithic Integrated
Circuit (MMIC) front-end Low Noise Amplifier (LNA) designed for
Global Positioning System/Global Navigation Satellite System
(GPS/GNSS) receiver applications. The device provides high
linearity, excellent gain, a high 1 dB Input Compression Point
(IP1dB), and a superior Noise Figure (NF). All critical matching
components are embedded inside the device. No external
matching components are required.
The SKY65601-477LF is optimized to operate at 1.5750 and
1.6018 GHz, which makes it ideal for GPS/GNSS radio receiver
applications.
The SKY65601-477LF is fabricated using advanced SiGe BiCMOS
technology. The LNA uses Surface Mount Technology (SMT) in the
form of a 2.0 x 1.3 mm Dual Flat No-Lead (DFN) 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.

Evaluation Board Description
The SKY65601-477LF Evaluation Board is used to test the
performance of the SKY65601-477LF LNA. The Evaluation Board
schematic diagram is shown in Figure 9. Table 5 provides the Bill
of Materials (BOM) list for Evaluation Board components.
An assembly drawing for the Evaluation Board is shown in
Figure 10. The layer detail is shown in Figure 11. Layer detail
physical characteristics are noted in Figure 12.
Package Dimensions
The PCB footprint drawing for the SKY65601-477LF is shown in
Figure 13. Package dimensions for the 6-pin DFN are shown in
Figure 14, and tape and reel dimensions are provided in
Figure 15.
Package and Handling Information
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 SKY65601-477LF is rated to Moisture Sensitivity Level 1
(MSL1) at 260 °C. It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
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.
