Qorvo RFSA2113TR13

The RFSA2113 is a fully integrated monolithic analog voltage-controlled attenuator featuring excellent linearity over a typical temperature-compensated 30 dB gain control range. The device offers bandwidth up to 18 GHz. It employs a revolutionary new circuit architecture that addresses long-standing industry challenges: high third-order intercept point, high attenuation range, low DC current, wide bandwidth, and temperature-compensated linear-in-dB control voltage characteristics. The attenuation level is set by a single positive control voltage, with integrated on-chip DC conditioning circuitry. The slope polarity of control voltage versus gain is selectable. The attenuator is matched to 50Ω across the rated control range and frequency, requiring no external matching components. Typical voltage-controlled attenuators in this performance class are based on compound semiconductor GaAs FET MMICs requiring 1 to 2 negative control voltages. This innovative product integrates a complete solution into a 3.2mm×3.2mm multi-chip laminate module, reducing board footprint and simplifying control compared to conventional compound semiconductor attenuator solutions.
