RFSA2023 Datasheet | Qorvo

® Voltage Controlled Attenuator Product Overview Qorvo's RFSA2023 is a fully monolithic analog voltage control attenuator (VCA) featuring exceptional linearity over 30d B adjustment range with on-chip temperature pensation. RFSA2023 incorporates a revolutionary new circuit architecture. It solved the long-standing industry problems of IP3, attenuation range, DC current, bandwidth, and temperature pensation. RFSA2023 is also designed with linear in d B control characteristic. There is no external analog supporting circuitry required. This attenuator is controlled by a single positive variable voltage with DC conditioning circuitry also on-chip. The slope of the attenuation versus control voltage is selectable. The RFSA2023 draws only 1m A current. It is internally matched to 50 Ω and works quite well over its rated ranges of control voltage and frequency. This game-changing product integrates the plete solution into a small 3mm x 3mm QFN package. That reduces the footprint by 20X in area and reduces the DC power by 10X over the PIN diode approaches.
