QPC3614

75Ω 5 −1500MHz Digital Step Attenuator

Product Overview

The QPC3614 is a 75Ω 6-bit digital step attenuator (DSA)

that features high linearity over the entire 31.5ꢁdB gain

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

of 1.2dB at 1ꢁGHz. The QPC3614 features three modes of

control: serial, latched parallel, and direct parallel

programming. Patented circuit architecture provides

overshoot-free transient switching performance. QPC3614

is available in a 20-pin 4.2mm x 4.2mm x 0.90mm QFN

package.
