RFSA2023 Voltage Controlled Attenuator Product Overview Qorvo s RFSA2023 is a fully monolithic analog voltage control attenuator (VCA) featuring exceptional linearity over 30dB adjustment range with on-chip temperature compensation. RFSA2023 incorporates a revolutionary new circuit architecture. It solved the long-standing industry 16 Pad 3x3mm QFN Package problems of IP3, attenuation range, DC current, bandwidth, and temperature compensation. RFSA2023 is also designed with linear in dB control characteristic. Key Features There is no external analog supporting circuitry required. This attenuator is controlled by a single Broadband 50MHz to6000MHz positive variable voltage with DC conditioning circuitry 30 dB Attenuation Range also on-chip. The slope of the attenuation versus control voltage is selectable. The RFSA2023 draws only 1mA +50dBm Input IP3 current. It is internally matched to 50 and works quite +80 dBm Input IP2 well over its rated ranges of control voltage and >+30 dBm High 1 dB Compression frequency. 1mA Low Current Consumption This game-changing product integrates the complete 3.3V Power Supply solution into a small 3mm x 3mm QFN package. That Linear in dB Control Characteristic reduces the footprint by 20X in area and reduces the DC power by 10X over the PIN diode approaches.
