PRECAUTIONS
• Please layout ground pattern under this FEM in order not to couple with RFIN and RFOUT terminal.
All external parts should be placed as close as possible to the FEM.
• For good RF performance, all GND terminals must be connected to PCB ground plane of substrate,
and via-holes for GND should be placed near the FEM.
