ADI ADRF6516ACPZ-R7

Программируемый фильтр, VGA31 МГцОбщее назначение

Overview

The ADRF6516ACPZ-R7 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 desired signal, thus reducing the bandwidth and resolution requirements on the analog-to-digital converters (ADCs). The excellent matching between channels and their high spurious-free dynamic range over all gain and bandwidth settings make the ADRF6516ACPZ-R7 ideal for quadrature-based (IQ) communication systems with dense constellations, multiple carriers, and nearby interferers.

The ADRF6516ACPZ-R7 operates from a 3.15 V to 3.45 V supply and consumes a maximum supply current of 360 mA when programmed to the highest bandwidth setting. When disabled, it consumes <9 mA. The ADRF6516ACPZ-R7 is fabricated in an advanced silicon-germanium BiCMOS process and is available in a 32-lead, exposed paddle LFCSP. Performance is specified over the −40°C to +85°C temperature range.
