Wide-bandgap semiconductors permit devices to operate at much higher voltages, frequencies, and temperatures than conventional semiconductor materials like silicon and gallium arsenide.
Concerns about power-amplifier heating and operating temps aren’t new as they affect device reliability and performance. However, RF designers must broaden the scope of thermal...
Discrete GaN transistors, whether in die or packaged forms, offer high power density to boost pulsed signals in C-, L-, and S-band radars and communications applications.
The market shift toward GaN transistors in 2021 isn’t just theoretical or inspirational—it’s happening now, with major companies designing and shipping products with GaN today...
Wide-bandgap materials such as gallium nitride (GaN) have emerged as technologies to take electronic performance to the next level. So, what’s “real” about GaN and what’s a myth...
A room-temperature bonding technique has been developed that provides an extremely thin bonding/interface layer between GaN substrate material and thermally conductive materials...
Leveraging the latest metal organic chemical vapor deposition technology, gallium-nitride-on-silicon is poised to meet the high-frequency demands of 5G and other platforms.
For a function that once required a tube amplifier, semiconductor amplifiers are raising pulsed power levels for radars and other applications at higher frequencies.
The characteristics of different substrates and device architectures make it possible to reach many speeds and frequencies with modern semiconductor devices and their packages...
Solid-state technology, mainly in the form of gallium-nitride transistors, is opening the door to more powerful, “tube-like” microwave power amplifiers.
Gallium nitride is no longer limited to power-amplification applications. Now all corners of the RF/microwave industry are taking advantage of the technology’s qualities.
If the mark of critical technology is that companies are willing to sue to protect it, and governments are blocking other countries from buying it, then gallium nitride will only...
GaN has emerged as the leading semiconductor material for high-power microwave switches and amplifiers, although GaAs is still the material of choice for low noise.
These two semiconductor building blocks have been fabricated in many forms, using many different semiconductor materials, in search of ideal, reliable performance at high frequencies...
