Overview
CXG1047FN Dual-Band 3V Power Amplifier for GSM900/DCS1800 Applications Description 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.
The amplifier can be configured for 2 separate inputs.
Power control is best achieved by variation of VDD1/VDD2 and VDD3 drain voltages with an external transistor.
A proposed power control circuit configuration is described.
External PMOS drain switch should be used to achieve low leakage.
