QPC6614
5 MHz to 6000 MHz, Digital Step Attenuator
The QPC6614 is a 6-bit digital step attenuator (DSA) that
features high linearity over the entire 31.5 dB gain control
range with 0.5 dB steps. The QPC6614 uses serial control
interface. The QPC6614 has a low insertion loss of 1.4 dB at
2 GHz. Patented circuit architecture provides overshoot-free
transient switching performance. The QPC6614 is available
in a 4.2 mm x 4.2 mm MCM package.
