TQP4M9071 Digital Step Attenuator Qorvo TQP4M9071 Digital Step Attenuator (DSA) is a high linearity, low insertion loss, 6-bit, 31.5 dB device with a 0.5 dB step size. The TriQuint Semiconductor TQP4M9071 DSA uses a single positive 3.3V or 5V supply and has a parallel control interface for changing attenuation states. The TQP4M9071 maintains high attenuation accuracy over frequency and temperature and requires no external matching components. This TriQuint Semiconductor DSA does not require external AC ground capacitors for operation above 700 MHz. The TQP4M9071 is optimized for use in a variety of applications, including general purpose wireless, test equipment and sensors, fixed wireless, 2G / 3G / 4G wireless infrastructure, base stations / repeaters, and GSM / CDMA / WCDMA / LTE.
