Evaluation Board Description
The SKY65050-372LF Evaluation Board is used to test the
performance of the SKY65050-372LF low noise transistor. An
assembly drawing for the Evaluation Board is shown in Figure 12.
The Evaluation Board schematic diagram is shown in Figure 13.
Table 6 provides the Bill of Materials (BOM) list for Evaluation
Board components.
The board is populated for 2.4 GHz operation and contains a
separate probe footprint for general device testing or source and
load pull characterization. The board is provisioned with two RF
connectors and a 3-pin DC launch. The RF connector and board
loss up to component C1 is approximately 0.15 dB at 2.4 GHz.
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 +3 V supply with a current limit of
Step 4: Apply RF signal or noise source and verify performance

Package Dimensions
The PCB layout footprint for the SKY65050-372LF is shown in
Figure 14. Typical case markings are shown in Figure 15.
Package dimensions for the 4-pin SC-70 are shown in Figure 16,
and tape and reel dimensions are provided in Figure 17.
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 SKY65050-372LF is rated to Moisture Sensitivity Level 3
(MSL3) 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
Application Note, Discrete Devices and IC Switch/Attenuators
Tape and Reel Package Orientation, document number 200083.
