Freescale selling GaAs business to Skyworks

Freescale selling GaAs business to Skyworks

The semiconductor giant has entered into an agreement to sell its RF power amplifier business to Skyworks, leaving a question mark hanging over the future of its "CS1" GaAs fab.

Freescale Semiconductor has agreed to sell its GaAs power amplifier (PA) business to fellow RFIC manufacturer Skyworks Solutions.

A spokesman for Freescale, which was acquired by a private equity consortium led by The Blackstone Group and The Carlyle Group in December 2006, confirmed that the deal had been struck, saying that it "represented good value for both companies".

The agreement includes GaAs PA designs, intellectual property, inventory and product lines, although it does not include Freescale's "CS1" wafer fab, located in Tempe, Arizona, and the site for the company’s GaAs device production.

As a result, a question mark now hangs over the future of that fab. Freescale says that it is looking at a number of potential options, but that "no definitive decision" has been made as yet.

While Freescale is a giant in the wider semiconductor industry, it has been a relatively small player in the PA sector. Strategy Analytics' Asif Anwar estimates that it holds less than a 1 per cent share of the overall market for GaAs RF components.

In contrast, rising demand among the dominant GaAs PA suppliers has seen many announce plans to expand manufacturing scale recently, with Skyworks set to switch from 4 inch to 6 inch wafer production at its HBT facility in Newbury Park, California (see related story).


Meanwhile, predictions of an increasingly consolidated GaAs industry have turned out to be correct, with the shareholders of RFMD and Sirenza Microdevices approving a merger in the past couple of days (see newsfeed entry).

Speculation over Freescale's entire RF semiconductor operation now looks likely to increase, with some expecting the business unit to be sold off, enabling a greater focus on software and services.

John Lau from the investment bank Jefferies believes that the CS1 fab may be closed in the near future, although Freescale insists that no decision has been made.

Lau also believes that the industry consolidation will be good for the remaining suppliers, in particular RFMD, who may be able to benefit from what he sees as product uncertainty at Freescale with increased shipments of its own Polaris 2 modules.

Asif Anwar says that more consolidation could follow, as the industry moves towards a point where there are just four or five major suppliers, and Japanese vendors increasingly employ an out-sourced manufacturing model.

Sharp enters the non-polar GaN fray

The leading diode laser and consumer electronics manufacturer is hoping to push GaN lasers to longer wavelengths for color display applications. The field of non-polar GaN lasers, currently dominated by Rohm Corporation and the University of California, Santa Barbara, now has another big player in the shape of Sharp Corporation. This firm's researchers, like the other groups, have turned to this material to avoid built-in polarization fields found in conventional c -plane GaN. These fields reduce laser output efficiency and shorten emission wavelengths, in a blue-shift effect that worsens at higher injection currents. Sharp's 400nm blue laser Non-polar m -plane GaN doesn't have these fields, so substrates made of this material are promising candidates for fabricating blue lasers with longer wavelengths, nearer the green part of the spectrum (see related stories). Therefore, rather than the 400 nm laser diodes it makes using c -plane GaN for its Blu-ray pla...

Toshiba claims GaN microwave power record

Toshiba claims GaN microwave power record The Japanese conglomerate turns up the power for high-definition satellite broadcasting with its Ku-band GaN-on-SiC HEMT. Toshiba has produced a GaN HEMT with an output power of 65.4 W at 14.5 GHz, that it hopes will replace competing electron-tube technologies in satellite applications. According to the Japanese company, this is the highest power-output FET to operate in the Ku-band, the region of the microwave spectrum between 12 and 18 GHz. Toshiba pushes Ku-Band amps Presented at European Microwave Week on October 8, the device will be sampled at the end of 2007 and should enter mass production in March 2008. The GaN HEMTs are marketed for high-capacity, high-definition satellite broadcasting base stations and high-power radar systems, which both require high-power amplifiers. “Demand is particularly strong for GaN devices, which offer advantages over GaAs devices in heat dissipation and high power performance characteristi...

White LEDs offer radio-free wireless option

White LEDs offer radio-free wireless option A photonic alternative to WLAN has been shown to exceed 100 Mbit/s and could provide bandwidth in a currently unlicensed area of the spectrum, if it can conform to general illumination standards. Thanks to white LEDs, overhead lighting could soon be used to transmit data over a RF-free wireless connection. That's according to Joachim Walewski from Siemens Corporate Technology, who has modulated the light emission from white LEDs in order to make a 101 Mbit/s wireless link with a PiN diode photodetector. “With this, you can have interference-free communication,” Walewski pointed out, adding that the visible spectrum is currently free of any requirements for communication licenses. Siemens is currently exploring the technology in order to keep pace with a competing Japanese collaboration that expects to bring similar technology to market by 2011, Walewski says. His Munich-based team claims to be the first to have boosted ...
