TOSHIBA EXPANDS HIGH POWER C-BAND GaAs FET PRODUCT LINE TO PROVIDE NEW SSPA MARKET OPPORTUNITIES FOR SATELLITE COMMUNICATIONS

New Devices are the First in the 6.4 to 7.2GHz, 7.1 to 7.9GHz and 5.3 to 5.9GHz Frequency Ranges and Offer the Highest Output Power Currently Available

SAN FRANCISCO, Calif., June 13, 2006— Committed to giving its customers the broadest range of leading-edge microwave products, Toshiba America Electronic Components, Inc. (TAEC)* today announced the availability of new C-Band gallium arsenide field effect transistors (GaAs FETs) that are the industry's first in each frequency range, and have the highest output power now available from a single device for that range. TAEC will be displaying its new C-Band GaAs FETs, along with other new microwave devices, in Booth #1046 at this year's IEEE MTT-S International Microwave Symposium, held June 13 through 15 in San Francisco.

These new devices, developed by Toshiba Corp. (Toshiba), expand Toshiba's 60W line-up that currently features parts in other C-Band frequency ranges. Designated TIM6472-60SL and TIM7179-60SL, they feature an output power of 48.0dBm (typical) and were developed for use in Solid State Power Amplifiers (SSPAs) for satellite communication and radar applications that are primarily supported by Traveling Wave Tube Amplifiers (TWTAs). In addition, Toshiba also added a new High Power GaAs FET, designated TIM5359-80SL, to its 80W line-up, which features an output power of 49.0dBm (typical)

Higher power SSPAs are in demand for both commercial and government satellite communications systems for a wide range of applications including global telecommunications, weather monitoring, airport traffic controlling, as well as defense and homeland security applications.

"Toshiba is the first to offer additional frequencies for the 60W and 80W C-Band GaAs FET, which means our customers can find expanded market opportunities in the new frequency range," said Christine Lee, business development manager for Microwave Devices at TAEC. "Coupled with our ability to provide the highest output power, Toshiba has a leading solution for next-generation SSPAs and microwave radars."

To simplify re-design, Toshiba maintained the footprint of new FETs. The 10V GaAs FET for 60W and 80W are offered in packages measuring 24.5mm x 17.4mm x 5.5mm.

Each of the new Power GaAs FETs are implemented in Toshiba's Heterojunction Field Effect Transition (HFET) process technology and employ Toshiba's cutting-edge ion implantation technology to enable development of the higher output FETs. The HFET process is ideal for high power microwave devices because of its high carrier concentration that enhances output power and gain. Toshiba plans to use this HFET process to develop additional 60W and higher output power devices for other C-Band frequency ranges as market conditions warrant.

Toshiba is an industry leader in microwave devices, with a history of industry achievements in output power, small size and performance. The company's family of C-Band components provides state-of-the-art power and efficiency for satellite communication applications, with a broad selection of Power GaAs FET products. The products are single-ended devices featuring high linearity, Class A operation and are hermetically sealed for high reliability.

About Solid State Power Amplifiers
Solid-state power amplifiers are an alternative to vacuum-tube technology for generating high power at microwave frequencies. Solid-state circuitry has been steadily replacing vacuum-tube technology for decades but one of the few applications that had resisted change was generation of high power in satellite earth station applications. With recent advances in solid-state microwave power devices, SSPAs now offer superior intermodulation characteristics, lower power consumption, lower operating costs, and longer life than traveling–wave tube amplifiers.
