Nokia Plans First Single-Chip GSM Phones
Not Single Chip
You still need a PA, power management chip and memory. You'd also need an application processor if you wanted a feature phone.
Now that i've clarified that, i must say i am happy to see this. They've been talking a single chips transceiver since the mid-90's and here it is. I assume its RF CMOS. I wonder how well it performs? Some of the transceiver chips which have been replaced were usualy made from bicmos or bipolar processes which used to offer better performance.
