Very bullish article Jim. But like most articles it creates more questions than it answers. Some I have are; A. This is the largest of several orders for double-oven crystal oscillator products received by Oak for the newest generation of CDMA base stations. either; (1)A manufacturer other than Oak has been supplying these components previously, or (2) The more expensive Rubidium based products were previously used, or (3)(my personal favorite) This signals the first production orders for the components that will build the hottest, most capable wireless base stations in the known universe! B. Who is the leading infrastructure provider that made this order? Nortel? ERICY? or could QCOM have more outstanding infrastructure contracts than were first realized? C. Finally, does the double oven method produce oscillators that are superior to Rubidium based oscillators or are they just more cost effective? Bux

Jim, Bux - Re: double oven crystal oscillator. While I do not know what a double oven is, crystal oscillators are often but in temperature control devices to improve their stability (i.e. so they more closely always oscillate at exactly the same frequency). While I do not know exactly what products CDMAOne basestations use for timing, there are two opposite ends of the spectrum choices: 1) Use a very imprecise source (e.g. quartz with no temperature control)and continually resync with GPS 2) Use a very precise source (e.g. Rubidium) and resync much less often or even sync between the various basestations. So it is possible that some basestation manufacturer is just switching from one scheme to another. There is no way to tell without knowing more about existing basestations. Clark
