Something that all radio amateurs encounter sooner or later is the subject of impedance matching. If you’d like to make sure all that power is transferred from your transmitter into the antenna and ...

What is impedance matching? Applications of impedance matching. Impedance matching and design considerations. Impedance (Z) matching is an essential part of most RF circuit design. Regardless of what ...

To use a smaller antenna, we need a higher signal frequency, and that’s what we do when we apply modulation to the signal. Modulation is simply encoding the low frequency signal in the information of ...
