POWER AMP MODULE
The RF5146 is a high-power, high-efficiency power amplifier module with integrated
power control that provides over 50dB of control range. The device is a self-con-
tained 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 applica-
tions 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 minimum switching transients.
The VRAMP limiter function is fully integrated into the CMOS controller and requires
no additional inputs from the user.
