Sony CXG1108K Datasheet
Power Amplifier Module for JCDMA
Description
The CXG1108K is the power amplifier module
which operates at a single power supply. This IC is
designed using the Sony’s original p-Gate HFET
process.
Features
• Single power supply operation:
VDD1 = VDD2 = 3.5V,
VGG = 2.95V (@High mode),
VGG = 2.7V (@Low mode)
• Ultrasmall package: 0.065cc (6.2mm × 6.2mm × 1.7mm)
• High efficiency: ηadd = 37.5% (@900MHz, POUT = 27dBm)
• Output power (high/low mode switching supported):
POUT ≤ 17dBm: Low mode (VGG = 2.7V)
POUT = 17 to 27dBm: High mode (VGG 2.95V)
• Gain: Gp = 26dB (@900MHz)
