An increasing number of new and proposed EMC standards are pushing the upper frequency test limits further up in the microwave spectrum. The latest EMC standard released, IEC 61000-4-3:2006, is no ...

The largest antenna ever tested in ESA's Hertz radio frequency test chamber is this 5-m diameter transponder antenna, which will operate down on the ground to help calibrate the Biomass mission, which ...

Digital signals are fundamentally electromagnetic waves added together. The higher the data rate required, the higher the frequency of the waves required to generate the signals. Once the signal ...

It used to be any good electronics experimenter had a bag full of crystals because you never knew what frequency you might need. These days, you are likely to have far fewer because you usually just ...
