GaN Versus Silicon For 5G


The global race to launch 5G mmWave frequencies could provide a long-anticipated market opportunity for gallium nitride (GaN) as an alternative to silicon. GaN is more power-efficient than silicon for 5G RF. In fact, GaN has been the heir apparent to silicon in 5G power amplifiers for years, especially when it comes to mmWave 5G networks. What makes it so attractive is its ability to efficie... » read more

Challenges Grow For 5G Packages And Modules


The shift to 5G wireless networks is driving a need for new IC packages and modules in smartphones and other systems, but this move is turning out to be harder than it looks. For one thing, the IC packages and RF modules for 5G phones are more complex and expensive than today's devices, and that gap will grow significantly in the second phase of 5G. In addition, 5G devices will require an as... » read more

A Novel Design Method of Highly Efficient Saturated Power Amplifier Based On Self-Generated Harmonic Currents


A novel design method without requiring the special harmonic termination circuit for a highly efficient power amplifier (PA) is proposed. The proposed PA is driven into saturated operation, from the linear to knee region, by adjusting the only fundamental load, and the saturated operation induces self-generated harmonic currents. The current and voltage waveforms can be shaped easily by the har... » read more

A Product Development Flow For 5G/LTE Envelope Tracking Power Amplifiers


Next-generation communication systems will rely on system architectures that will challenge component level design. This NI AWR software white paper examines the use of envelope tracking (ET), digital pre-distortion, and impedance matching via load pull to improve the efficiency and linearity performance of RF PAs targeting 4G and 5G applications.

RF SOI Foundry Biz Heats Up


The foundry business is undergoing a new round of acquisition and fab expansion activity. As before, the big foundry vendors are getting bigger, while some may fall by the wayside. And at times, the events cause some uncertainty, if not jitters, in the supply chain. For example, [getentity id="22819" comment="GlobalFoundries"]in October signed a definitive agreement to acquire the chip uni... » read more
