Electrical Specifications
The AC and DC specifications for the power amplifier interface signals. Refer to Table 3 for the DC voltage and
current specifications. Refer to Figures 3 through 14 for the RF performance.
Absolute Maximum Stress Ratings (Applied conditions greater than those listed under “Absolute
Maximum Stress Ratings” may cause permanent damage to the device. This is a stress rating only and
functional 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 con-
ditions may affect device reliability.)
