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 apply unless otherwise stated in
the tables below:
T
A
= -40°C to +85°C
VCC = 3.3V, IOVCC = 3.3V
RF system performance specifications are guaranteed
on National Semiconductor Austin Board rev1.0b refer-
ence design platform.
