F0448 Dual Matched Broadband RF DVGA 3.3GHz to 4.2GHz Datasheet The F0448 is a 3.3GHz to 4.2GHz 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: DSA0, a single 6dB step using a single control pin; DSA1, a 23dB SPI-controlled gain ad
