Product Overview

The QPC3624 is a

75Ω 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 1.2

dB at 1 GHz. The QPC3624 features three modes of

control:

serial,

latched

parallel,

and

direct

parallel

programming.

Patented
