PA MODULE FOR CDMA2000 (450–460 MHZ)
DATA SHEET • SKY77148
Characterization Data
The graphs from Figure 2 through Figure 8 illustrate the
characteristics of a typical SKY77148 power amplifier designed
for operation in the PCS frequency band (450–460 MHz). This
amplifier was selected by characterizing a group of devices and
choosing a part with average electrical performance for both
nominal and the full range of recommended operating conditions,
including worst case limits.
The graphs illustrate the digital signal characteristics of the
SKY77148. Shown are power sweep characteristics for key
performance parameters over temperature and frequency, up to
29.5 dBm output power. The data was taken up to and including
16 dBm output power with the bias mode control pin setting of
VCONT = 2.5 volts. Beyond 16 dBm output power, the VCONT was set
to zero volts.
