Evaluation Board Description
The Skyworks SKY65152 Evaluation Board is used to test the
performance of the SKY65152 power amplifier module. The fol-
lowing design considerations are general in nature and must be
followed regardless of final use or configuration.
1. Paths to ground should be made as short as possible.
2. The ground pad of the SKY65152 power amplifier module has
3. Bypass capacitors should be used on the DC supply lines. RF
4. The RF lines should be well separated from each other, with

Evaluation Board Test Procedure
Use the following procedure to set up the SKY65152 evaluation
board for testing.
1. Connect a 5.0 V supply to V
2. If desired, connect a voltage meter to V
3. Connect a signal generator to the RF signal input port. Set it to

special electrical and thermal grounding requirements. This
pad is the main thermal conduit for heat dissipation. Since
the circuit board acts as the heat sink, it must shunt as much
heat as possible from the amplifiers. As such, design the con-
nection to the ground pad to dissipate the maximum wattage
produced to the circuit. Multiple vias to the grounding layer are
required.
