  • n. a device which switches electronic circuitry so that a radio antenna can function as either a transmitting or receiving antenna.

Examples

  • Or, when the received echoes of early radar systems coincide with the transmitter signal and are drowned out by it, they add a set of parts together called a duplexer that turns off the transmitter for a small fraction of a second so that the incoming echo can be received.

    The Nature of Technology

  • What I love enough more than the built-in webserver is the duplexer.

  • The bad news is, the duplexer on the new printer didn't work all that well, and skipped a page around page 80, so by the time I got done printing the first half of the manuscript, it was pretty much all buggered up.

    flick! flick! flick your workload!

  • And so you're still seeing dramatic increases there in the RF, if you go from a couple of bands of 2G to adding to 3G the extra switch bands, and the duplexer content, you're still seeing about a multiplier of 2x to 3x of what you had in 2G by itself.

  • I think the real growth is when we include the duplexer.

  • So you'll see switch duplexer models, very well-suited to go with the converged power amplifiers.

  • In many cases it's likely to be discrete amplifiers and discrete filters, duplexer filters.

  • As I mentioned earlier, one band requires, in theory, one duplexer, discrete duplexer, and one PA.

  • The whole concept is, as you need more and more interfaces, 3G or UMTS, multiple bands, LTE add-on for the bands, bands being different parts of the frequency, you basically, theoretically, you have a duplexer and a PA for every band.

  • So, the duplexer content will definitely grow very linearly with the complexity of smartphones as we move to higher wireless bandwidth over time.
