General Description
The TQP4M9071 is a high linearity, low insertion loss, 6
bit, 31.5 dB Digital Step Attenuator (DSA) operating over
the DC – 4 GHz frequency range. The digital step
attenuator uses a single positive +3.3 V or +5 V supply
and has a parallel control interface 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.
