Qorvo TQP4M9071 & TQP4M9072 Digital Step Attenuators
Qorvo TQP4M9071 and TQP4M9072 Digital Step Attenuators are high linearity, low insertion loss, 6-bit, 31.5dB digital step attenuators (DSA) operating over the DC to 4GHz frequency range. The TQP4M9071 can operate with either a 3.3V or 5.0V supply, and has a parallel control interface for changing attenuation states. The TQP4M9072 uses a single positive 5.0V supply and has a serial periphery interface (SPITM) for changing attenuation states. Both devices maintain high attenuation accuracy over frequency and temperature. No external matching components are needed for either DSA. The TQP4M9071 and TQP4M9072 have an added feature of not requiring external AC ground capacitors for operation above 700MHz.
The Qorvo TQP4M9071 and TQP4M9072 Digital Step Attenuators are available in a standard 4mm x 4mm QFN24 package, and are footprint and pin compatible.
