APPLIED CIRCUIT BOARD EXAMPLES
PRECAUTIONS
1. Please locate L1 close to LNAIN terminal (11).
2. Please locate C4 close to LNACAP terminal (10).
3. Please locate L5 close to VLO terminal (3).
4. Please locate C8 close to L5.
5. Please connect exposed GND PAD (bottom side of IC) to PCB GND using through holes as many
6. Please design the PCB structure that the dielectric thickness between the surface layer and the
GND layer (directly under) is set to 0.2mm or more, about PCB of this device and external parts.
However, the terminal of TAB GND of this device and the GND of external parts does not have
these restrictions. Please design the GND layer pattern that can reduce a parasitic GND
inductance as much as possible.
