Characterization Data

The following graphs illustrate the characteristics of a typical

CX77112 Power Amplifier Module 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.

characteristics of the CX77112. 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.
