The Frequency Diplexer as a Combiner 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 spectrum. The focus of this article is the latter, the combining of two...

The Anti-Parallel Series Pair Limiter Topology The PIN Diode and the Anti-Parallel Configuration The PIN diode itself was invented by Jun-ichi Nishizawa in 19501, just 18 days before R. N. Hall of General Electric. Hall would go on to propose the PIN diode as a rectifier in 19522, and a decade later the anti-parallel PIN...
