Instantaneous Bandwidth - A Feature Without A Benefit?

July 30, 2003 9:59 am | Product Releases | Comments

By Thomas Mullineaux, OPHIRRF Inc. Look at most RF power amplifier data sheets destined for the EMC market, and you will see the feature 'Instantaneous Bandwidth' proclaimed as though it is a major benefit to the end user. So what is this feature exactly? Basically, instantaneous bandwidth means that all parts of the frequency band covered by the amplifier are available immediately, with no need to wait for something to 'switch in' ...
