In cases where this is important, e.g. when making radiation pattern tests, it is important that radiation and pickup only occur from the antenna. In these cases a balun is essential. Where radiation close to the transmitter must be minimised: If some of the radio frequency signal ...
What is a Balun? A balun is an electrical transformer that is used to convert electrical signals to and from balanced and unbalanced signals. They are normally used to connect lines that have different levels of impedance and are commonly used in the home for connecting HD and traditional anten...
An example of a PCB stack-up is shown below. In this example, the stack-up implements a 4-layer structure with two internal plane layers (L02_GND for ground, and L03_PWR for power). This type of stack-up is appropriate for IoT devices, lightweight embedded systems, and many other des...
