Cree Releases High Power Ku-Band PA

30W amplifier offers 20dB linear gain at 42dBm average output power

Cree has released what it claims is the highest power Ku-Band MMIC available on the market. Covering the 13.5 to 14.75GHz commercial satcom band, the new 30W GaN MMIC two-stage high power amplifier (HPA) will allow the satcom industry to achieve higher power, more efficient Ku-Band solutions than the incumbent TWT or GaAs solutions used today.

Available in a 25mm x 9.6mm, 10-lead, metal/ceramic flanged package or as a bare die, the 50Ω Ku-Band MMIC HPA operates at 40V VDD, and delivers satcom measured performance of 20dB linear gain at 42dBm average output power, while maintaining linearity under the -33dBc OQPSK signal, and with adjacent channel power at a drain efficiency of 20 percent. 

According to Cree, the new 30W GaN MMIC HPA also delivers higher breakdown voltage, power density, and thermal conductivity than comparable silicon, GaAs, or GaN-on-silicon transistors, in addition to wider bandwidth performance.

"Cree's new Ku-Band GaN MMIC HPA was specifically designed in response to customer requests for higher power and higher efficiency Ku-Band amplifier solutions. Delivering higher power, gain, and efficiency at an affordable price point, this amplifier will set the new standard for Ku-Band performance," said Tom Dekker, director of sales and marketing, Cree RF.

The new 30W Ku-Band GaN MMIC will be on display at the 2015 International Microwave Symposium (IMS), which will take place May 17-21 in Phoenix, Arizona, and will be stocked at Digi-Key and Mouser by mid-summer 2015. 



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.
