Abstract

Biasing power amplifiers (PA) in aerospace and defense applications can be expensive, hard to scale, and require a large area of board space to implement. The AFE20408 addresses these issues by integrating eight digital-to-analog converters (DACs), an analog-to-digital converter (ADC), and fast gate bias switches into a small 5mm x 5mm package. This application note also details power-on sequencing requirements and the multiple output configurations of the AFE20408.
