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.
Svea 123 stove. The Svea 123 is a small liquid-fuel (naphtha, commonly referred to as white gas or Coleman fuel) pressurized-burner camping stove that traces its origins to designs first pioneered in the late 19th century.
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.
A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.

A diplexer is to allow two signals to be carried over a single path - i.e. to provide two-channel multiplexing. 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 ...
The first gas stove was developed in 1802 by Zachäus Winzler , but this along with other attempts remained isolated experiments. [16] James Sharp patented a gas stove in Northampton, England in 1826 and opened a gas stove factory in 1836. His invention was marketed by the firm Smith & Philips from 1828.
The magic comes from the way it prevents signals from propagating between certain ports under specific conditions. This allows it to be used as a duplexer ; for instance, it can be used to isolate the transmitter and receiver in a radar system while sharing the antenna.
