duplexer

[′dü‚plek·sər]
(electronics)
A switching device used in radar to permit alternate use of the same antenna for both transmitting and receiving; other forms of duplexers serve for two-way radio communication using a single antenna at lower frequencies. Also known as duplexing assembly.

Since the typical noise power of a CDMA transmitter in the Bx band is -135 dBm/Hz, (1) if the duplexer's Tx-Rx isolation is larger than about 50 dB, then [n.sup.i.sub.Tx] [approximately equal to] 1 and [F.sub.max] [approximately equal to] 9 or [NF.sub.max] [approximately equal to] 9.5 dB.
