The Mini-Circuits DAT-31R5A-SP+ is a 50 Ohm digital step attenuator designed for wideband operation from DC to 4.0 GHz. It offers adjustable attenuation ranging from 0 to 31.5 dB, with precise 0.5 dB steps.
This attenuator features a high IP3 of +52 dBm typical and a good VSWR of 1.2:1 typical, facilitating easy interfacing with adjacent components and minimizing amplitude ripple. It is immune to latch-up and provides excellent return loss of 20 dB typical.
The DAT-31R5A-SP+ series supports both serial and parallel control interfaces, offering flexibility in system integration. It can operate with a single positive supply voltage (+2.3 to +3.6V) or dual supplies (+2.7 to +3.6V positive and -3.6 to -3.2V negative), with overall usable positive operating voltages ranging from +2.3/2.7 to 5.2V.
Constructed using a unique CMOS process on silicon, this attenuator provides GaAs-like performance with the advantages of conventional CMOS devices. It is housed in a compact 4.0 x 4.0 mm surface mount package (Case Style DG983-2), making it suitable for various applications in communications, satellite, and defense industries.
