AWU6605
The AWU6605 power amplifier module is based on
ANADIGICS proprietary HELP3™ technology. The
PA is designed to operate up to 17 dBm in the low
power mode, thus eliminating the need for three gain
state, while still maintaining low quiescent current
and high efficiency in low and medium power levels.
The PA can still be operated as 3 gain state device
if the customer chooses to. The directional “daisy
chainable” coupler is integrated within the PA module,
therefore there is no need for external couplers.
The AWU6605 has an integrated voltage regulator,
which eliminates the need for an external constant
voltage source. The PA is turn on/off is controlled
by V
EN
pin. A single V
MODE
control logic (V
MODE1
) is
needed to operate this device.
The DG09 power distribution (figure 15) highlights
the need to improve the current consumption in low
and medium power level. The AWU6605 is designed
to operate up to 17 dBm in the low power mode with
very low quiescent current. Current consumption for
AWU6605 is also plotted in the figure 5.
HELP3
AWU6605 requires only two calibration sweeps for
system calibration, thus saving calibration time.
Figure 16 shows one application example on mobile
board. C1 and C2 are RF bypass caps and should
be placed nearby pin 1 and pin 10. Bypass caps
C9 and C5 may not be needed. Also a “T” matching
topology is recommended at PA RF
IN
and RF
OUT
ports to provide matching between input TX Filter and
Duplexer / Isolator.
