1.3.2 Power Amplifier (U103)
The power amplifier that can be used in the CDMA mode has linear amplification capability.
For higher efficiency, it is made up of one module (Monolithic Microwave Integrated Circuit) for which
RF input terminal and internal interface circuit are integrated onto one IC after going through the GaAs
HBT (heterojunction bipolar transistor) process.
The module of power amplifier is made up of an output end interface circuit including this module.
The maximum power that can be inputted through the input terminal is 8dBm and conversion gain is
about 28.5dB. RF transmit signals that have been amplified through the power amplifier are sent to
the duplexer.
