Where We Are Now
Radio Frequency (RF) power semiconductors, especially for wireless infrastructure, have always been a difficult business. Constant technical issues and the introduction of new technology, intense competition, and cyclical business environments keep things in a quasi-state of perpetual flux. Coupling this with the fact that it is still an “expert-based business” that ships hundreds of millions of parts per year does not help.
As 4G/Long-Term Evolution (LTE) infrastructure is built out, this market segment will flatten out, and perhaps even decline a bit. This has caused most vendors in this space to search out markets outside of wireless basestation systems. This is no easy task; collectively, the other segments of RF power under 4 Gigahertz (GHz) and >3 Watts (W) amount to about half of the current wireless and mobile infrastructure business.
Added to this mix over the last year or so are new drivers that can potentially have serious effects on the RF power semiconductor marketplace. Thes…
