DSuirfgacietaMlouSnttep Attenuator
DAT-15R5A+ Series
50Ω 0 to 15.5 dB, 0.5 dB Step DC to 4.0 GHz
The Big Deal
• Wideband, operates up to 4 GHz
• Immune to latchup
CASE STYLE: DG983-2
• High IP3, 52 dBm
Product Overview
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.
Key Features
Feature
Advantages
Wideband operation, specified from DC
to 4.0 GHz
Can be used in multiple applications such as communications, satellite and defense,
reducing part count.
Serial or parallel interface
Good VSWR, 1.2:1 typ.
Models available with serial or parallel interface mode to suit customer demand.
Eases interfacing with adjacent components and results in low amplitude ripple.
Single positive supply models:
(Model suffixes: -SP+ and –PP+)
+2.3 to +3.6V
Use of single positive supply simplifies power supply design. An internal negative voltage
generator supplies the desired negative voltage. Single positive supply results in excellent
spurious performance, -140 dBm typical.
Dual supply models:
(Model suffixes: -SN+ and –PN+)
+2.7 to +3.6V (Positive) and
-3.6 to -3.2V (Negative)
Dual supply provides spurious-free operation. It also allows fast switching up to 1 MHz (vs.
25 kHz for single supply).
Wide range fo positive operating voltages allows the DAT-15R5A+ Series of models to be
used in a wide range of applications. See Application Note AN-70-006 for operation above
+3.6V
Useable over a wide range of supply
voltages, +2.3/2.7 to 5.2V
Footprint compatible to DAT-15R5-XX+
Series (XX=SN/SP/PN/PP)
Can fit into existing footprint and provide improved performance.
