Power Amplifier Module for JCDMA
Description
The CXG1178K 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 mode),
1.5V (Mid mode),
1.0V (Low mode),
V
GG
= 2.8V
Ultrasmall package: 0.027cc (4.5mm
4.5mm
1.35mm)
High efficiency:
add = 40.5%@P
OUT
= 27.5dBm (High mode),
add = 17.6%@P
OUT
= 14dBm (Mid mode)
Output power (High/Mid/Low mode switching supported):
P
OUT
= 18 to 27.5dBm: High mode,
P
OUT
= 14 to 18dBm: Mid mode,
P
OUT
14dBm: Low mode
Gain (High mode): Gp = 28.5dB (@900MHz)
