SAN FRANCISCO, June 14 / -- Toshiba America Electronic Components, Inc. (TAEC)* today announced the addition of two internally-matched Extended Ku-Band power gallium arsenide field effect transistors (GaAs FETs) that provide wider frequency ranges to meet various regional spectrum requirements around the world for applications in satellite communications. Developed by Toshiba Corp. (Toshiba) the new GaAs FETs will be showcased, along with other Toshiba microwave products, in TAEC's booth, #1046, at this year's IEEE MTT-S International Microwave Symposium, held June 13 through 15 in San Francisco, California.

The 9-watt (W) Toshiba TIM1314-9L features high power output of 39.5 decibels relative to 1 milliwatt (dBm) at a frequency range of 13.75 to 14.5 gigahertz (GHz), compared to the 14.0 to 14.5GHz range of typical Ku-Band FETs. The TIM1314-9L is ideal for use in Block Upconverter modules in Ku-Band transceivers for Very Small Aperture Terminals (VSAT). The device is offered in the 9.7mm x 17.0mm package used for Toshiba's 2W, 4W, 7W and 14.0 to 14.5GHz 9W Ku-Band GaAs FETs, enabling the TIM1314-9L to be used as a drop-in replacement for these devices to increase power output or frequency range in existing designs.

Toshiba's 30W TIM1314-30L is the highest power device of its class currently offered for the solid-state power amplifier (SSPA) market with a power output of 45.0dBm (typ.), and now supports a broader frequency range than Toshiba's previous 30W Ku-band FET. The new device is designed for high power SSPAs used in earth or base stations for satellite communication applications such as those used as replacement for Traveling Wave Tube Amplifiers (TWTA).

"Toshiba has been a recognized leader in advanced technology for internally matched, high power GaAs FETs for C-band and Ku-band since the late 70s. We have been working closely with our OEM customers to continue to advance the technology for this market, and these extended Ku-band devices have been developed in response to customer demand to meet varying bandwidth requirements worldwide," said Christine Lee, business development manager, Microwave Devices, for TAEC.

The TIM1314-9L and TIM1314-30L GaAs FETs are implemented in Toshiba's Heterojunction Field Effect Transition (HFET) process technology and employ Toshiba's cutting edge ion plantation technology to enable development of the highest output FETs. The HFET process is idea for high power microwave devices because of its high carrier concentration that enhances output power and gain.

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.
