Description

       AT4201 is a single-chip solution that provides power management and control for LNB. It provides the bias, control and detection of FETs and mixers necessary for LNB, as well as the functions of stable power and other power for IF amplifiers. The AT4201 is a 16-pin miniature package that requires only three external components to provide a compact solution. As the most critical part of LNB, in control monitoring, power management, etc., AT4201 can exert stable performance to eliminate the effects of misoperation and overload.
