CXG1108K
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 x 6.2mm x 1.7mm) * High efficiency: add = 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) Applications Power amplifier for JCDMA system cellular phones Structure p-Gate HFET module Recommended Operating Conditions VDD = 3.3 to 4.2V VGG = 2.95V1% (High Mode) 2.7V1% (Low Mode) Absolute Maximum Ratings * Operating case temperature * Storage temperature * Bias voltage * Bias voltage * Input power 8 pin LCC (Ceramic)
