Mitsubishi Electric's Ku-band GaN HEMT Goes Into Orbit

The firm has developed a gallium nitride device for satellite earth stations, which it believes will reduce the number of high frequency amplifiers needed, by half
Mitsubishi Electric Corporation has developed a GaN high-electron mobility transistor (HEMT) Ku-band (12–18GHz) amplifier for satellite earth stations.


The MGFK47G3745 features an output power of 50W at 24V high-voltage operation, linear gain of 9dB and power added efficiency of 30 percent, 10 points greater than its predecessor, the MGFK44A4045.


Mitsubishi says it expects the device to reduce the number of high frequency amplifiers by half and contribute to greater power saving and downsizing for power transmitter equipment.

The module also has an output power meeting 3rd-order inter modulation (IM3) of -25dBc of 43dBm and is internally impedance-matched. The IDQ (Quiescent Drain Current ) is 1A and the frequency is 13.75 – 14.5 GHz (Ku band).

In recent years, the use of GaAs amplifiers in microwave power transmitters has been increasingly replaced with GaN amplifiers due to their high breakdown-voltage, power density and saturated electron speeds.


Satellite-based communication, especially in the Ku-band, enables communication to be established under adverse conditions, such as during natural disasters, and in areas where communication facilities are hard to build. Mobile earth-based stations require in-vehicle portability and must be easy to install, so power-saving measures and downsized power transmitters are highly useful in helping to minimise the size of earth stations.


Mitsubishi Electric will begin shipping samples of the MGFK47G3745 on October 1st.


Moving forward, Mitsubishi Electric expects to expand its lineup of Ku-band satellite earth stations.


 




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.
