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. CELLULAR PA OUT PCS CDMA OUT QCPM-9801 Rev.
