High-speed broadband and fiber optic devices used across a variety of communication and military and aerospace applications require circuits that couple RF signals. Since this involves removing the DC component and allowing only the high-frequency AC component to pass or bypass, this can be a complicated process. The blocking capacitor needs to present a near reflectionless transition at the frequency the line is seeing and at a bandwidth that allows the entire signal to pass without degradation.
As RF and microwave systems require higher performance in a small footprint, designers and engineers need to get more out of every component, including capacitors. To meet these demands, Knowles Precision Devices has expanded its line of single-layer vertical electrode (V Series) capacitors to include the 100nF V80 Bypass Capacitor. The V80 is a revolutionary development for capacitors as it is the first SLC to feature an operating voltage of 50V in .084” x .042” package. The closest competitor product at this size is only rated for 16V.
Many circuits in broadband applications require the coupling of RF signals, which can be a complicated process since it involves removing the DC component to allow only the high-frequency AC component to pass or bypass. Removing the AC component from a DC line is done by placing a coupling capacitor in series with the path the signal takes.
