What are harmonics in RF systems? A given signal’s second harmonic is approximately twice the given signal’s fundamental frequency. Ideally, amplifiers are expected to have zero non-linearities in the ...

The industrial, scientific, and medical (ISM) radio frequency bands find common use in electronics systems, by virtue of their comparatively lightly regulated nature versus (for example) spectrum ...

With the recent exponential growth of communications data, the available frequency bands are crowded, and the trend is to move up in frequency to increase the modulation bandwidth. This requirement ...
