F0448 Overview
The F0448 is a 3.4GHz to 3.8GHz dual RF digital variable gain amplifier (DVGA) designed for use in receivers. This dual RF DVGA provides two independent receiver channels each with 13dB typical maximum gain and 6dB noise figure designed to operate with a single +5V supply. For each channel, gain control is split into three separate attenuators:.
