TQP4M9072

Overview

The TQP4M9072 is a high linearity, low insertion loss digital step attenuator (DSA) operating from DC to 4 GHz. It features a 6-bit resolution with 31.5 dB total attenuation range and utilizes a serial peripheral interface for state control. The device operates on a single positive 5.0V supply and is housed in a 24-VFQFN exposed pad package.
