General Description
The TQP4M9083 is a high linearity, low insertion loss, 7-bit,
31.75 dB Digital Step Attenuator (DSA) operating over the
0.4–3.5GHz frequency range. The digital step attenuator uses
a single positive 5V supply and has a serial periphery
interface (SPITM) for changing attenuation states. This
product maintains high attenuation accuracy over frequency
and temperature. No external matching components are
needed for the DSA.
The TQP4M9083 is available in a standard lead-free
/green/RoHS-compliant 24-pin 4x4mm QFN package. The
TQP4M9071 and TQP4M9072 are also available from
TriQuint as a footprint and pin compatible 6-bit, 31.5dB DSA
with a parallel control interface and serial control interface
respectively.
