I can't see any application where a second power amp would be needed if your trying to do either CDMa or WCDMa in the same band.

No design experience but I can usually manage to read a data sheet. I dont know of any power amps that support both 1x/DO and WCDMA in the same device.

Would you mind point me to the DO/WCDMA power amps?

I might be missing something obvious, but I just dont see it.

In most of their chipsets adding DO tot he chipset costs pennies.

Q has been saying that for the last 7 years....and yet they keep coming out with multiple versions of the same chipset. The Snapdragon series currently has two chips. The QSD8250 supports HSPA and the QSD8650 supports both HSPA and DO.

Why offer two chips if it really is only pennies more expensive to add in the DO support? Wouldnt it be in Q's best interest to just offer one chip and make it as cheap as possible to offer worldmode devices? The fact that they dont take this path seems to indicate that there are some non-trivial costs on both the chip and handset side to going multimode.
