www.DataSheet4U.com RM009 Power Amplifier Module for Dual-band GSM900 DCS1800 The RM009 is a dual-band Power Amplifier Module (PAM) designed in a compact Distinguishing Features form factor for Class 4 GSM900 and Class 1 DCS1800 cellular handsets. • High efficiency GSM 54% DCS 45% Input/output matching 50 Ω internal Small outline 9.1 mm x 11.6 mm Low profile 1.50 mm ±10% Low APC current 60 µA The module consists a GSM900 PA block and a DCS1800 PA block, matching circuitry for 50 Ω input and output impedances, and bias control circuitry. Two separate Heterojunction Bipolar Transistor (HBT) PA blocks are fabricated on a single Gallium Arsenide (GaAs) die. One PA block operates in the GSM900 band and the other supports the DCS1800 band. The PAM is optimized for three-cell operation with both PAs sharing common power supply pins to distribute current. A custom CMOS integrated circuit contains a current amplifier that minimizes the required power control current (IAPC) to 60 µA, typical. • • • • RF input and output ports are internally matched to 50 Ω to reduce the number of Applications external components for a dual-band design. Switching circuitry receives the band select signal on the band select pin (BS) to switch between GSM (logic 0) • Class 4 GSM900 and Class 1 and DCS (logic 1). Analog Power Control (APC) controls the output power of DCS1800 dual-band cellular handsets each PA selected by the band select signal. The extremely low leakage current (2 µA, typical) of the RM009 dual-band module maximizes handset standby time. The functional block diagram shows the relationship of the dual PAs and the CMOS device in the RM009.
