com RM008 PA Module for Dual-band GSM900 and DCS1800 Applications The RM008 is a dual-band Power Amplifier Module (PAM) designed in a compact form factor for Class 4 GSM900 and Class 1 DCS1800 operation.
The PAM consists of two Gallium Arsenide (GaAs) Heterojunction Bipolar Transistor (HBT) power amplifiers and internal components that match the RF input and output ports to 50 ohms, which reduces the number of external components for a dual-band design.
Optimized for lithium-ion battery operation, both PAs share common power supply pins to distribute current.
The RM008 dual PAM has extremely low standby current, which maximizes handset standby time.
A block diagram of the RM008 is shown below.
The Analog Power Control (APC) pins (GSM APC and DCS APC), control output power level.
Table 4 of this data sheet shows the complete signal pin assignments and descriptions of the RM008 dual-band Power Amplifier Module.
Distinguishing Features • High efficiency GSM 50% DCS 45% I...
