Qorvo's TQP4M9083 is a high linearity, low insertion loss, 7-bit, 31.75 dB Digital Step Attenuator (DSA) operating over the 0.4 to 3.5 GHz frequency range. The digital step attenuator uses a single positive 5 V supply and has a serial periphery interface (SPI™) 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 Qorvo as a footprint and pin compatible 6-bit, 31.5 dB DSA with a parallel control interface and serial control interface respectively.
