Key Features
- 75 ohm, 6-bit, 3.15dB range, 0.5dB step
- Frequency Range 47-2000 MHz
- Overshoot-free Transient Switching Performance
- High Linearity
The QPC3624 is a 6-bit digital step attenuator (DSA) that features high linearity over the entire 31.5 dB gain control range in 0.5 dB steps and has a low insertion loss of 1.3 dB at 1 GHz. The QPC3624 features three modes of control: serial, latched parallel, and direct parallel programming. Patented circuit architecture provides overshoot-free transient switching performance. The QPC3624 is available in a 24-pad 4 mm x 4 mm x 0.85 mm QFN package.
