General Description

Pin Configuration

The TQP4M9072 is a high linearity, low insertion loss, 6

bit, 31.5ꢀdB Digital Step Attenuator (DSA) operating over

the DCꢀ–ꢀꢀGHz frequency range. The digital step

attenuator uses a single positive +5ꢀV supply and has a

serial periphery interface (SPI^TM) for changing

attenuation states. This product maintains high

attenuation accuracy over frequency and temperature.

No external matching components are needed for the

DSA. The product has an added feature of not requiring

external AC ground capacitors for operation above 700

MHz.
