F0443 Overview
The F0443 is a highly integrated 0.6GHz to 2.7GHz dual channel RF digital variable gain amplifier designed for use in diversity/MIMO receivers. The F0443 provides two independent receiver paths each with 29.5dB typical maximum gain and 3.2dB NF at 2.5GHz. For each path, gain control is split into four separate digital step attenuators:.
