Features, Applications

The a 2-bit digital step attenuator (DSA) that features high linearity over the entire 18dB gain control range in 6dB steps. The QPC3213 uses a parallel control interface and has a low insertion loss at 2GHz. The patented circuit architecture provides overshoot-free transient switching performance using a single to +5V power supply. The QPC3213 is available in an industry standard 12 pad 3mmx3mm QFN package that is lead-free and RoHScompliant

Frequency Range 2-Bit, 18dB Range, 6dB Step Overshoot-free Transient Switching Performance High Linearity, Input IP3>+55dBm Parallel Control Interface Fast Switching Speed, 80nsec Typical

Single Supply to +5V Operation 1.8V Logic Compatible RF Pins Have No DC Voltage, Can be DC Grounded Externally Patented Circuit Architecture Power-up Default Setting Is Maximum Attenuation
