GENERAL DESCRIPTION

The ADL5592 is a digitally programmable variable gain amplifier (VGA) designed for use from 250 MHz to 2400 MHz. Two digitally programmable attenuators are cascaded with a high linearity fixed-gain amplifier. The device also includes a mixer, which can be used to mix the transmitted signal into an adjacent receive band for loopback testing.
