Diplexers/Multiplexers with Reduced Prototyping Diplexers/Multiplexers with Reduced Prototyping

Diplexers and multiplexers are used to either separate or combine two different frequencies that are similar in range to one another. While bandpass filters can also be used to combine and separate signals, they’re only ideal for use with frequencies that are far apart from one another.
