Mini-Circuits DAT-31R5A-PN+

The DAT- 31R5A+ series of 50Ω digital step attenuators provides adjustable attenuation from 0 to 31.5 dB in 0.5 dB steps. The control is a 6- bit serial/parallel interface, and the attenuators operate with either a single positive or dual (positive and negative) supply voltage. DAT- 31R5A+ series models are produced by a unique CMOS process on silicon, offering the performance of GaAs with the advantages of conventional CMOS devices. The DAT- 31R5A- PN+ is a 50Ω RF digital step attenuator that offers an attenuation range of 31.5 dB in 0.5 dB steps. The control is a 6- bit parallel interface, operating on dual supply voltage (positive & negative). The DAT- 31R5A- PN+ is produced using a unique CMOS process on silicon, offering the performance of GaAs, with the advantages of conventional CMOS devices.
