TSP #240 – Rohde & Schwarz 70GHz, 75dB Electromechanical Step Attenuator Teardown & Failure Analysis

In this episode Shahriar takes a look at a very high-end step attenuator designed by Rohde & Schwarz for their FSU family spectrum analyzers which cover over 67GHz of sweep frequency.

The attenuator teardown and architecture is thoroughly presented with focus on how the high-frequency performance is maintained in a moving environment. Furthermore, the individual attenuator pads are examined under the microscope for their construction and design where the 5dB pad failure can also be observed.
