New 110 dB, 10 MHz to 8 GHz, Electronic Step Attenuator for Fast-Switching Microwave Signal Generators
A step attenuator finds wide-spread usage as a means of accurately extending the attenuation range of test and measurement instruments. A typical application would be to extend the output amplitude range of a microwave signal generator. Often an amplitude control loop can accurately set the power or gain level over three or four decades of range, but frequently this is not enough range. Historically, the mechanical step attenuator has been the preferred solution.
