The digital step 6 RF IN attenuator uses a single positive +3.3V or +5V supply 7, 8, 9, 10, 11, 12 ACGND0-ACGND5 and has a parallel control interface for changing 13 RF OUT attenuation states. This product maintains high 18 VDD attenuation accuracy over frequency and temperature. No external matching components are needed for the 19, 20, 21, 22, 23, 24 D0D5 DSA. The product has an added feature of not requiring 5, 14 GND external AC ground capacitors for operation above 700 Backside Pad GND MHz. The TQP4M9071 is available in a standard lead-free /green/RoHS-compliant 24-pin 4x4mm QFN package. Ordering Information Also available from TriQuint is the TQP4M9072, a Part No. Description footprint and pin compatible DSA with a serial control TQP4M9071 6 Bit, 31.5 dB DSA interface.
