GENERAL DESCRIPTION
The ADL5330 is a high performance, voltage controlled, variable gain amplifier (VGA)/attenuator for use in applications with frequencies up to 3 GHz. The balanced structure of the signal path minimizes distortion while it also reduces the risk of spurious feedforward at low gains and high frequencies caused by parasitic coupling. While operation between a balanced source and load is recommended, a single sided input is internally converted to differential form.
