Characterization Data

The graphs in Figure 2 through Figure 8 illustrate the

characteristics of a typical CX77140 power amplifier designed for

operation in the CDMA/AMPS frequency band (824–849 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

CX77140. Shown are power sweep characteristics for key

performance parameters over temperature and frequency, up to

28 dBm output power. The data was taken up to and including

16 dBm output power with the bias mode control pin setting of

to 0 volts.
