#148 - Diplexores y Duplexores ¿Son lo mismo?

In this episode of CQ on Frequency, we clarify one of the most confusing topics in radio frequency: diplexers, duplexers, and triplexers. Although they may appear similar on the outside, their function, design, and applications are completely different, and misusing them can range from poor operation to equipment failure. Throughout this episode, we explain: What a diplexer actually is and how it works electrically How it differs from a duplexer and why they aren't interchangeable What parameters to consider: losses, SWR, isolation, and power Real-world use cases in the shack: Two radios and one antenna One radio and two antennas Sharing coaxial cable Repeaters Using a diplexer in full-duplex satellite operations with two walkie-talkies And when it makes sense to use a triplexer A practical episode, with real-world examples and clear explanations, designed for both those starting to delve into RF and those already familiar with electronics. 🎧 If you've ever wondered, "Is this worth it or not?", this episode is for you.
