Data Sheet
Microchip Technology Company
Electrical Specifications
The DC and RF specifications for the power amplifier are specified below. Refer to Table 3 for the DC voltage
and current specifications. Refer to Figures 3 through 9 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.)
Input power to pin 3 (P
