Programmable Attenuators Step 30 MHz to 40 GHz (.PDF Download)

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...
