Introduction

The DAT- 15R5A+ series of 50Ω digital step attenuators provides adjustable attenuation from 0 to 15.5 dB in 0.5 dB 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. DAT- 15R5A+ 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- 15R5A- PP+ is a 50Ω RF digital step attenuator that offers an attenuation range up to 15.5 dB in 0.5 dB steps. The control is a 5- bit parallel interface, operating on single (positive) supply voltage. The DAT- 15R5A- PP+ is produced using a unique CMOS process on silicon, offering the performance of GaAs, with the advantages of conventional CMOS devices.
