Power Control Scheme
2-Mode Control Scheme
This control scheme doesn’t require DC-DC converter.
Vcont changes PA into Low Power Mode or High Power
Mode, which results in 2-mode control without DC-DC
converter. WS2512-TR1G is designed to change the
mode at 16 dBm output power.
3-Mode Control Scheme (Step Voltage Control)
This control scheme requires DC-DC converter. When
DC-DC converter is used, Vcc voltage as well as Vcont can
be changed, which results in 3-mode control scheme —

Low/Mid/High power mode. Vcc changes at 7 dBm
output and Vcont changes at 16 dBm output. Voltages
for Vcc are 1.5 V for low power mode and 3.4 V (battery
voltage) for mid and high power mode.
PAE graphs for 2-mode control and 3-mode control are
shown in Figure 27 and Figure 28.
HSDPA
WS2512-TR1G meets stringent HSDPA linearity require-
ment up to 27dBm. WS2512-TR1G can operate up to
28 dBm with Rel.99, which has a lower PAR than HSDPA.
