Description

       The AT4200 is a single-chip solution that provides power management and control for LNBs. It provides the bias, control and detection, local oscillator switches, and stable power and other power supplies for IF amplifiers that are necessary for LNBs and mixers Features. The AT4200 is a 16-pin miniature package that requires only three external components to provide a compact solution. As the most critical part of LNB, the AT4200 can exert stable performance to eliminate the effects of misoperation and overload in terms of control monitoring and power management.
