10.0 General Specifications
Absolute Maximum Ratings (see
Table 7
) indicate limits be-
yond which damage to the device may occur. Operating
Ratings (
see
Table 8
) indicate conditions for which the device is in-
tended 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:
