duplexer & diplexer

[elf61]

Hi
What is duplexer? what is diplexer? define. In which book I can find related materials?
Happy saturday!

A diplexer is a three-port frequency-dependent device that may be used as a separator or a combiner of signals


A duplexer is a device which allows a transmitter operating on one frequency and a receiver operating on a different frequency to share one common antenna with a minimum of interaction and degradation of the different RF signals.

Can you provide any figure/block diagram? In Which book I can find equations describing it?

The Duplexer is a device, which separates two frequencies within the same band, while the Diplexer is a device which separates two different bands.
The Duplexer requires much more selective circuits usually using high quality Band Pass Filters, while the Diplexer normally using one Low Pass Filter and one High Pass Filter.

A duplexer is a device that combines two or more signals onto a common channel or medium to increase its transmission efficiency.

duplex is a device for one common port ,for example antenna, which can serve as the transmit and receive, and other two port, wchih is Tx and Rx, the diplex infact is a frequency combiner, that is the difference of the two concept!
