DATA SHEET • SKY77149
PA MODULE FOR CDMA / PCS (1850–1910 MHz)
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. Figure 2 through 8 illustrate the digital signal
characteristics of the SKY77149. Shown are power sweep
characteristics for key performance parameters, over temperature
and frequency, up to 28.5 dBm output power. The data was taken
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.
