These are effectively a higher-performance version of a diplexer, typically with a narrow split between the two frequencies in question (typically around 2%-5% for a commercial two-way radio system). With a duplexer the high- and low-frequency signals are traveling in opposite directions at the shared port of the duplexer.
The diplexer is a different device than a passive combiner or splitter. The ports of a diplexer are frequency selective; the ports of a combiner are not. There is also a power "loss" difference - a combiner takes all the power delivered to the S port and equally divides it between the A and B ports. A diplexer does not.
Generally a diplexer consists of a pair of filters with non-overlapping pass-bands, so it implements frequency-division multiplexing. I agree that a device can be both a diplexer and duplexer - if it is a diplexer where the two signals travel in opposite directions (as in the diagram). However this does not mean that diplexer and duplexer are ...
In same-band repeaters, isolation between transmitter and receiver can be created by using a single antenna and a device called a duplexer. The device is a tuned filter connected to the antenna. In this example, consider a type of device called a band-pass duplexer. It allows, or passes, a band, (or a narrow range,) of frequencies.
Learn the difference between a Hispanic, Latino, and Spanish person. Hispanic describes a Spanish-speaking person while Latino is for people from Latin America.
It's a question that I think leaves most of us scratching our heads -- what exactly is the distinction between being Latino, Hispanic or Spanish? There's a difference, of course, between ethnicity ...
An orthomode transducer (OMT) is a waveguide component that is commonly referred to as a polarisation duplexer. Orthomode is a contraction of orthogonal mode . Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. [ 1 ]
It can be hard to drink less, for many people, socializing seems to revolve around food and alcohol. Our culture has normalized drinking alcohol as part of a way of life…and our biochemistry ...
