CXG1156K
10 pin LCC (Ceramic)
Power Amplifier Module for JCDMA
Description
The CXG1156K 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:
V
DD1
= V
DD2
= 3.5V (High power mode),
1.3V (Low power mode 1),
1.0V (Low power mode 2),
V
GG
= 2.7V
Small package: 0.065cc (6.2mm
6.2mm
1.7mm)
High efficiency:
add = 40%@P
OUT
= 27.5dBm (High power mode),
add = 23%@P
OUT
= 15dBm (Low power mode 1)
Output power (high/low power mode switching supported):
P
OUT
= 18 to 27.5dBm: High power mode,
P
OUT
= 15 to 18dBm: Low power mode 1,
P
OUT
15dBm: Low power mode 2
Gain: Gp = 29dB (@900MHz)
