ORDERING INFORMATION PACKAGE TYPE NUMBER NAME UBA1710M SSOP20 DESCRIPTION plastic shrink small outline package; 20 leads; body width 4.4 mm PARAMETER(1) analog supply voltage digital supply voltage peak supply current in power-up mode operating ambient temperature MIN. 4.2 4.2 − −20 TYP. 4.8 4.8 12 − GENERAL DESCRIPTION UBA1710M 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 amp...
