PA MODULE FOR CDMA / PCS (1850–1910 MHZ)
DATA SHEET • CX77107
Characterization Data
The graphs from Figure 2 through Figure 10 illustrate the
characteristics of a typical CX77107 power amplifier designed for
operation in the PCS frequency band (1850–1910 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
CX77107. 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
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 0 volts.
