TriQuint TQP4M Series High Linearity Digital Step Attenuators

TriQuint TQP4M Series High Linearity
Digital Step Attenuators

TriQuint's TQP4M Series High Linearity Digital Step Attenuators are a high linearity, low insertion loss, Digital Step Attenuator (DSA). The digital step attenuator uses a single positive 3.3V or 5V supply and has a parallel control interface or 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.

Features
  • Interface:
    • TTL / CMOS Compatible Parallel Control  (TQP4M9071)
    • Serial Control Interface (TQP4M9072 & TQP4M9083)
  • No requirement for external bypass capacitors for operation above 700 MHz
  • 50 Ω Impedance
  • +3.3V or +5V Supply Voltage
Applications
  • Mobile Infrastructure
  • LTE / WCDMA / CDMA / EDGE
  • Test Equipments and Sensors
  • IF and RF Applications
  • General Purpose Wireless
