In most any wideband RF front end (RFFE), the system bandwidth is limited by some means, even if that limitation is a simple preselector. Often a wideband RFFE that is connected to an antenna must meet aggressive rejection parameters to avoid being desensitized by...

Frequency diplexers (henceforth simply diplexers) serve to either divide (demultiplex) the frequency spectrum into two major sub-bands or perform the complementary function of frequency multiplexing where the two sub-bands are combined to form a full frequency...

Astonishingly, 200 years ago in France in 1826, Felix Savary observed the oscillatory nature of Leyden jar discharges. This oscillatory behavior is an essential requirement for resonance.1 The theory of resonance would take another 50 years to mature. In 1887,...
