The QPC3213 is a 2-bit digital step attenuator (DSA) that features high linearity over the entire 18 dB gain control range in 6 dB steps. The QPC3213 uses a parallel control interface and has a low insertion loss of 0.8 dB at 2 GHz. The patented circuit architecture provides overshoot-free transient switching performance using a single +3 V to +5 V power supply.
The QPC3213 is available in an industry standard 12 pad 3 mm x 3 mm QFN package that is lead-free and RoHScompliant.
