Description

The Dual-Band Tri-Mode Power Amplifier Module (PAM) QCPM-9804 offers a highly integrated solution for CDMA dual-band tri-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 provide: 32.5 dBm Pout and 47% Power Added Efficiency (PAE) at 3.4 V in AMPS mode, and 28.5 dBm Pout and 29% PAE at 3.4 V in cellular CDMA mode. While the PCS power amplifier achieves 28.5 dBm Pout and 28 % PAE at 3.4V in PCS mode.

The QCPM-9804 is designed with dynamic bias control to optimize the PAE at low output power in PCS and cellular CDMA mode to maximize the system talk time. The surface mount RF MultiPak insures cost, size, and high volume manufacturing advantages over other traditional approaches.
