CXG1047FN Overview
The CXG1047FN dual band GaAs PA is a 3-stage power amplifier that may be used for both GSM900 and DCS1800 applications. To achieve minimum die-size and package dimensions, it contains one amplifier chain with a single input and output. The PA has a single RF input for both the GSM900 and DCS1800 transmit signals.
CXG1047FN Key Features
- Single positive rail only
