1.3.1.2 PCS CDMA transmit signal path performance specifications
1.3.2 Dual Power Amplifier(U106)
The power amplifier that can be used in the PCS and CDMA mode has linear amplification capability and high
efficiency. For higher efficiency, it is made up of one MMIC (Monolithic Microwave Integrated Circuit) for which
RF input terminal and internal interface circuit are integrated onto one IC after going through the AlGaAs/GaAs HBT
(heterojunction bipolar transistor) process. The module of power amplifier is made up of an output end interface
circuit including this MMIC. The maximum power that can be inputted through the input terminal is +10dBm and
conversion gain is about 28dB. RF transmit signals that have been amplified through the power amplifier are sent to
the quintplexer.
