General Description
The Dual-Band Dual-Mode Power
Amplifier Module (PAM) offers a
highly integrated solution for
CDMA
dual-band
Dual-mode
handsets. The integrated solution
leads to improvements in cost,
size, performance, and reliability.
This PAM also offers several
features that will make handset
design more flexible and robust.
The module contains two power
amplifiers (PCS and Cellular PAs),
two driver amplifiers with power
control and bias circuits.
The cellular power amplifiers
provides : 29 dBm Pout and 44%
Power Added Efficiency (PAE) at
3.4 V in AMPS mode. While the
PCS power amplifier achieves 28.5
dBm Pout and 28 % PAE at 3.4V in
PCS mode. The PAM is designed
with dynamic bias control to
optimize the PAE at low output
power in PCS mode to maximize
the system talk time.
The surface mount RF MultiPak
insures cost, size, and high volume
manufacturing advantages over
other traditional approaches.
