ADRF6520ACPZ General Description

The ADRF6520 is a matched pair of fully differential low noise and low distortion programmable filters and variable gain amplifiers(VGAs). Each channel is capable of rejecting large, out of band interferers while reliably boosting the wanted signal, thus reducingthe bandwidth and resolution requirements on the analog-to-digital converters (ADCs). The excellent matching betweenchannels and their high spurious-free dynamic range over all gain and bandwidth settings make the ADRF6520 ideal forquadrature-based (IQ) communication systems with dense constellations, multiple carriers, and nearby interferers. Thefilter corners, enable, and dc offset correction loop enable are all programmable via a serial peripheral interface (SPI).
