RF Power for Wireless Infrastructure Flat to Slightly Down, but Other Segments Up


RF power semiconductor devices continue to be a nearly US$1.5 billion business (<4 GHz, >3 W) despite the variability with the wireless infrastructure segment. Wireless infrastructure accounts for nearly two-thirds of total revenue and has been flat to slightly up and then slightly down in recent years. The other major segments are:

  • Military/defense
  • Instrumentation/Scientific/Medical (ISM)
  • Broadcast
  • Commercial avionics and air traffic control
  • Non-cellular communications

All are showing solid mid-single-digit growth except for broadcast, which is anemic but still moving upward.

Technology Is Starting to Drive the Market


Gallium Nitride (GaN) devices are making strides in all segments except for broadcast. Improvements in manufacturability and attempts to fully commercialize GaN on Si all indicate that wireless infrastructure could be in the cards for GaN as its share in this important segment improves se…
