Mini-Circuits DAT Digital Step Attenuators

Mini-Circuits DAT Digital Step Attenuators provide adjustable attenuation from 0 to 15.5dBin 0.5dB steps. The control is a 5-bit serial/parallel interface, and the attenuators operate with either single positive or dual (positive and negative) supply voltage. The devices are produced by a unique CMOS process on silicon, offering the performance of GaAs with the advantages of conventional CMOS devices.

Features

  • Wideband operation, specified from DC to 4.0GHz
  • Serial or parallel interface
  • Good VSWR, 1.2:1 typ
  • Single positive supply models: (Model suffixes: -SP+ and –PP+) +2.3 to +3.6V
  • Dual supply models: (Model suffixes: -SN+ and –PN+) +2.7 to +3.6V (Positive) and -3.6 to -3.2V (Negative)
  • Useable over a wide range of supply voltages, +2.3/2.7 to 5.2V
  • Footprint compatible with DAT-15R5-XX+ Series (XX=SN/SP/PN/PP)
  • Safe attenuation transitions
