QPC3624

75Ω 47−2000ꢀMHz Digital Step Attenuator

Product Overview

The QPC3624 is a 75Ω 6-bit digital step attenuator (DSA)

that features high linearity over the entire 31.5ꢀdB gain

control range in 0.5 dB steps and has a low insertion loss

of 1.2ꢀdB at 1ꢀGHz. 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 4mm x 4mm x 0.90 mm

QFN package.
