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

  • 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.

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

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

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