Most ham radio operators will build an antenna of some sort when they first start listening or transmitting, whether it’s a simple dipole, a beam antenna like a Yagi, or even just a random wire ...

In many communication transceiver designs, an unbalanced single-ended signal must be converted to a balanced differential signal. This task is often considered routine, and a flux-coupled transformer ...

Balun bandpass filters represent a critical advancement in radio frequency (RF) circuit design, integrating the dual functions of balanced-to-unbalanced conversion and frequency selection. These ...
