Characterization Data
This section contains two complete sets of performance graphs. One set describes operation in the
Korean PCS band and the other set describes US PCS operation.
Korean PCS Band (1720–1780 MHz)
The following graphs illustrate the characteristics of a typical RI23110 power amplifier selected
for operation in the Korean PCS band. This amplifier was selected by characterizing a group of
devices and selecting a part with average electrical performance at both nominal and worst case
(limit) conditions. Figures 1 through 9 illustrate the digital signal characteristics of the RI23110 in
the Korean PCS band.
