I would like to point out that creating modem chips is probably way harder than it seems. It requires knowledge not available to mere mortals. Can you design a new ARM chip with a GPU? Great, you are at most a demi-god. You probably have to be true master of the Universe to be able to design real RF chips. Working with RF seems to be a completely different game than high frequency digital circuitry. When you work with high frequency digital signals you are kind of touching RF stuff, but it is more like you do things that "are known to work" rather than completely understanding everything that is happening.
