RF Duplexer manufacturers | RF Diplexer manufacturers

This page covers RF duplexer manufacturers and RF diplexer manufacturers or vendors. It mentions RF duplexer/diplexer manufacturers with email ids,websites and their basic specifications.

What is RF Duplexer:
The three port RF device used to separate frequency bands of wireless system which are closer to each other. For example GSM duplexer separates uplink (890 to 915 MHz) and downlink (935 to 960 MHz) frequency bands. This is shown in the figure-1 below.

The RF duplexer can be constructed from RF circulator as well as using PIN diode switches. It is used to share single antenna between the transmitter and receiver parts of a transceiver. Refer difference between duplexer vs diplexer>> and Triplexer basics>>.
