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.

UBA1710Mincludes 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 UBA1710M 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.
