The TriQuint TQP4M9072 is a high linearity, low insertion loss, 6-bit, 31.5 dB digital step attenuator (DSA) operating over the DC to 4 GHz frequency range. The digital step attenuator uses a single positive 5 V 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 product has an added feature of not requiring external AC ground capacitors for operation above 700 MHz.

The part is available in a standard lead-free / green / RoHS-compliant 24-pin 4 x 4 mm QFN package. The TQP4M9071 is also available from TriQuint as a footprint and pin compatible DSA equivalent with a parallel control interface.
