Product specification
Modulator for GaAs power amplifiers
UBA1710M
FEATURES
Power MOS modulators for control of GaAs power
amplifier drain voltage
Power control loop amplifier and MOS driver
Voltage tripler for supply of MOS driver
Positive-to-negative DC converter for GaAs power
amplifier gate biasing.
APPLICATIONS
Control of GaAs power amplifiers for GSM and DCS
hand-held transceivers.
GENERAL DESCRIPTION
The UBA1710M integrates the functions required to
operate the GaAs Power Amplifiers (PAs) from the
CGY20xx family which are intended for GSM and DCS
applications.
It includes a negative supply for PA gate biasing and most
of the functions required to implement power control so
that only a very few external component are required.
The power control section integrates two power MOS
devices for control of the PA drain voltages, an MOS driver
and a feedback loop amplifier. The MOS driver is supplied
from an on-chip voltage tripler.
