1. NC = No Connection
2. VEE is internally generated and must remain isolated from
external power supplies. Generated noise is typical of
switching DC-DC Converters
3. Connections and external components shown in func-
tional schematic are required. 0.1 µF Capacitors need to
be located near pins 30 & 32.
4. The exposed pad centered on the package bottom must
be connected to RF and DC ground. (For PQFN Pack-
ages)

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
Moisture Sensitivity
The MSL rating for this part is defined as Level 2
per IPC/JEDEC J-STD-020. Parts shall be stored
and/or baked as required for MSL Level 2 parts.
