ELECTRICAL SPECIFICATIONS

The DC and RF specifications for the power amplifier

are specified below. Refer to Table 5-2 for the DC volt-

age and current specifications.

Absolute Maximum Stress Ratings (Applied conditions greater than those listed under “Absolute Maxi-

mum Stress Ratings” may cause permanent damage to the device. This is a stress rating only and func-

tional operation of the device at these conditions or conditions greater than those defined in the operational

sections of this data sheet is not implied. Exposure to absolute maximum stress rating conditions may

affect device reliability.)
