Summary

The AMC7908 is an all-in-one PA biasing controller. The integrated DAC, ADC, and switches help eliminate a majority of the discrete components often seen in PA controller systems while providing additional benefits. The flexible output switch structure allows for four to eight individual gate biasing points, along with simultaneous LDMOS and GaN gate control. The ADC provides the system with precise PA voltage, current, and temperature monitoring. The integrated nature of the AMC makes sure the PA gates are turned off when the ADC detects an alarm. In addition to the turn on sequencing control, the AMC7908 is a very robust PA controller that can benefit any system that requires a PA.
