Characterization Data
The following graphs illustrate the characteristics of a typical
SKY77149 power amplifier designed for operation in the cellular
frequency band (824–849 MHz). This amplifier was selected by
characterizing a group of devices and then selecting a part with
average electrical performance for both nominal and the full
range of recommended operating conditions, including worst case
limits.

up to and including 8 dBm output power with the bias mode
control pad setting of VCONT = 1.25 volts and from 10 dBm to
16 dBm output power with the bias mode control pad setting of
VCONT = 1.55 V. Beyond 16 dBm output power, VCONT was set
to 2.0 V.
