• Power StarTM Module
The RF5146 is a high-power, high-efficiency power ampli-
fier module with integrated power control that provides
over 50dB of control range. The device is a self-contained
7mmx7mmx0.9mm lead frame module (LFM) with 50
Ω
input and output terminals. The device is designed for use
as the final RF amplifier in GSM850, EGSM900, DCS and
PCS handheld digital cellular equipment and other appli-
cations in the 824MHz to 849MHz, 880MHz to 915MHz,
1710MHz to 1785MHz and 1850MHz to 1910MHz
bands. With the integration of a VRAMP limiting circuit, the
RF5146 can regulate the VRAMP voltage to ensure mini-
mum switching transients. The VRAMP limiter function is
fully integrated into the CMOS controller and requires no
additional inputs from the user.
