TriQuint estimates that the TWTA market opportunity will be about $600 million by 2015.

TriQuint Semiconductor, Inc has announced that it has acquired CAP Wireless (Newbury Park, CA) and its patented Spatium RF power combining technology that replaces traveling wave tube amplifiers (TWTAs) in communications and defence systems.

TriQuint estimates that the TWTA market opportunity will be about $600 million by 2015. 

The acquisition leverages TriQuint’s position as a gallium nitride (GaN) pioneer and CAP Wireless’ high power RF solid state amplifier system expertise.  The combined company now offers a wider selection of high power / high frequency products. CAP Wireless’ Spatium technology adds to the exceptional bandwidth, efficiency and ruggedness of TriQuint’s product portfolio.

Spatium technology dramatically improves broadband RF power efficiency through the use of patented coaxial spatial combining techniques. Spatium provides other performance advantages including solid-state reliability, smaller form factors, higher power densities and reduced weight compared to either TWTA-based systems or conventional planar power combining products. Spatium can provide faster time-to-market and can seamlessly incorporate GaN MMIC performance breakthroughs while reducing product lifecycle costs.

TriQuint Vice President and General Manager for Infrastructure and Defence Products, James L. Klein, noted that TriQuint’s acquisition of CAP Wireless merges a unique approach to high power RF amplifier system design with the benefits of TriQuint GaN device technology.

“CAP Wireless initially developed its Spatium amplifier platform using gallium arsenide-based (GaAs) MMICs. GaN-based products from TriQuint can elevate Spatium to new levels of efficiency, power density, frequency coverage and output power."

CAP Wireless’ Spatium products are currently being sold and designed into several U.S. and international defense and commercial programs. TriQuint will focus Spatium technology development as a solution for high efficiency power applications in commercial and defence markets, including electronic warfare (EW), communications and radar. TriQuint’s reliable supply of high performance MMICs, combined with its volume manufacturing expertise will benefit immediate and long-term customer requirements for Spatium-based and conventional amplifier products.

TriQuint is continuing operation of CAP Wireless product sales and contracts while it develops new devices based on Spatium technology using TriQuint GaN and GaAs MMIC amplifiers.

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.
