Power Amplifier Module for Dual-band GSM900 DCS1800
The RM009 is a dual-band Power Amplifier Module (PAM) designed in a compact
form factor for Class 4 GSM900 and Class 1 DCS1800 cellular handsets.
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
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)
and DCS (logic 1). Analog Power Control (APC) controls the output power of
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.
