RF Power Semiconductors Have Just Become a More Complex Business

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.
