Amplitude control over wide bandwidths is essential for many commercial and military applications, and system architects often rely on digitally controlled PIN-diode attenuators to do the job. Typical applications include benchtop and automated test equipment, fading simulators for multiple-input, multiple-output (MIMO) communications systems, radar, and electronic-warfare (EW) systems. To serve these requirements, Fairview Microwave recently launched a line of digitally programmable step attenuators that cover wide frequency ranges well into the millimeter-wave region with attenuation steps as small as 0.03 dB...
