new RFSA3013 and RFSA3023 are fully monolithic analog voltage-controlled attenuators (VCAs) featuring
exceptional linearity over a 30dB minimum gain control range. These VCAs also feature internal
temperature compensation that provides an attenuation profile highly insensitive to temperature changes.
Each VCA is controlled by a single positive control voltage with on-chip DC conditioning circuitry. The
slope of the control voltage versus gain is selectable. These VCAs have been characterized for 75Ω CATV
applications over the full attenuation and frequency ranges with no external matching components
required. The components are offered in a compact 3mm x 3mm QFN package.
