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.
While there are a number of broadband blocking capacitors on the market today, many struggle to provide low insertion loss over a broad frequency range. But not Knowles Precision Devices’ Broadband Milli-Cap® capacitor. Milli-Cap is designed to be the ideal single-piece construction surface mount (SMT) capacitor for broadband applications up to 50 GHz (most competitors only support up to 40 GHz).
