I'm surprised we haven't heard more already from those working at both of these companies. Clearly, this is a significant occurence in the industry. It opens up all kinds of possibilities and brings together two very complementary companies.
I'm really glad to see this merger. My impression from both of these companies is that they aren't afraid to get out ahead and try new technologies. I learned so much from TriQuint about GaN, and so much from RFMD about picocells. Glad to see both sides of the ecosystem coming together. Looking forward to seeing what comes of this.
