6.0 Electrical Specifications

6.1 GENERAL SPECIFICATIONS

Absolute Maximum Ratings (see Table 9) indicate limits

beyond which damage to the device may occur. Operating

Ratings (see Table 10) indicate conditions for which the

device is intended to be functional.

This device is a high performance RF integrated circuit and

is ESD sensitive. Handling and assembly of this device

should be performed at ESD free workstations.

The following conditions are true unless otherwise stated in

the tables below:

• TA = -40°C to +85°C

• VCC = 3.3V

• RF system performance specifications are guaranteed

on National Semiconductor Austin Board rev1.0b refer-

ence design platform.
