Toshiba C-band GaN HEMTs Support SATCOM Market

The gallium nitride module are optimised for high power, gain and efficiency to support extended C-band applications
Toshiba America Electronic Components, Inc. (TAEC) and its parent company, Toshiba Corp., have announced the expansion of their GaN HEMT line-up.

TAEC has added three new devices optimised to support extended C-Band SATCOM applications.

The TGI5867 broadband GaN HEMT family is targeted to block up convertors (BUCs) and solid state power amplifiers (SSPAs).

The devices will be exhibited this week in Toshiba's booth, #2027 , at the 2013 IEEE MTT-S International Microwave Symposium from June 4th to 6th in Seattle, Washington.

Toshiba's new TGI5867 family supports extended C-Band (5.85 to 6.725 GHz frequency range) satellite communications, enabling satellite operators to offer more service and data traffic capacity to the market.

The TGI5867 GaN HEMT family operates in the 5.85 to 6.725 GHz range, with available power ratings of 25W, 50W and 100W. The TGI5867-100L has an output power at 100W or 50.0dBm2 (typ.) with an input power of 20W or 43dBm (nom.), linear gain at 11.0dB2 (typ.) and power added efficiency of 38 percent2. The TGI5867-50L and 25L have an output power at 50W2 (typ.) and at 25W2 (typ.), linear gain at 13.0dB (typ.) and power added efficiency of 40 and 45 percent, respectively.

"The expansion of our GaN HEMT product family brings high gain, high power and broadband features that help designers build energy-efficient SSPAs and BUCs," notes Homayoun Ghani, business development manager, microwave devices, for TAEC's Discrete Business Unit.

Ghani continues, "By adding the 100W, 50W and 25W line-up to our GaN HEMT product family, Toshiba is now able to provide a full GaN HEMT-base SSPA design solution for extended C-Band SATCOM applications. This solution will help microwave designers eliminate multiple power supply rails and reduce the number of parts in their overall system."

Samples of the Toshiba extended C-Band GaN HEMT family will be available in Q3 of 2013.


AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
