Evaluation Board Description
The SKY65049-360LF Evaluation Board is used to test the
performance of the SKY65049-360LF low noise amplifier. An
assembly drawing for the Evaluation Board is shown in Figure 12.
The Evaluation Board schematic diagram is shown in Figure 13.
Table 5 provides the Bill of Materials (BOM) list for Evaluation
Board components.
Input and output trace lengths have been minimized to reduce
losses. All surface mount components are 0402-sized to reduce
component parasitics. The use of 0603 or larger components is
not recommended. Component spacing has also been minimized.
The board is provisioned with two RF connectors and a DC
launch. The RF connector and board loss up to component C1 is
approximately 0.1 dB at 2.0 GHz.
It is very important to place multiple ground vias as close to shunt
components as possible. This ensures proper grounding and
circuit performance.
Board material is 10 mil thick VT47 FR4 with 1 oz. copper
cladding. RF input and output traces are 50 Ω.
Evaluation Board Test Procedure
Step 1: Connect RF test equipment to amplifier input/output SMA
Step 2: Connect DC ground.
Step 3: Connect VDD to a +5 V supply with a current limit of
Step 4: Apply RF signal or noise source.

100 mA. Verify that the board draws approximately
65 mA.

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 SKY65049-360LF is rated to Moisture Sensitivity Level 1
(MSL1) at 260 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.
Production quantities of this product are shipped in a standard
tape and reel format. For packaging details, refer to the Skyworks
