As an RF engineer, whether you are building a 5G antenna to mount on top of a street light or a satellite that will be launched into space, you are likely being asked to reduce three key factors – size, weight, and power (SWaP). The need to reduce SWaP is becoming increasingly common, but also increasingly tricky, because even though wavelength and the corresponding critical dimensions decrease as frequency goes up, RF circuits generally scale in size and complexity with the wavelengths supported. Thus, it can be really difficult to find companies who are up for the challenge of providing components that are designed to help reduce SWaP

To ensure Knowles Precision Devices (KPD) customers achieve optimal performance and are successful with our products, we have compiled a number of techniques to mitigate PCB variation and reduce the unwanted effects of microstrip technology (e.g. cross talk and radiation).
