Power Amp Wars Begin For 5G
By Mark LaPedus - 24 Aug, 2020 - Comments: 2

Demand is increasing for power amplifier chips and other RF devices for 5G base stations, setting the stage for a showdown among different companies and technologies. The power amplifier device is a key component that boosts the RF power signals in base stations. It's based on two competitive technologies, silicon-based LDMOS or RF gallium nitride (GaN). GaN, a III-V technology, outperforms ... » read more

5G Brings New Testing Challenges
By Bryon Moyer - 11 Aug, 2020 - Comments: 0

As 5G nears commercial reality, makers of chips and systems that will support 5G will need to take on the standard burden of characterizing and testing their systems to ensure both performance and regulatory adherence. Millimeter-wave (mmWave) and beamforming capabilities present the biggest testing challenges. “5G is expected to have the extended coverage plus the bandwidth to harness ... » read more

By Jim Martens and David Zima The IoT has increased the demand for good radio frequency (RF) design practices from the mains, to wall outlet power, all the way to the antenna. With several IoT standards employed today, constraint management has become critical to ensuring that designs meet product performance and reliability. Even the simplest of IoT designs can benefit from constraint ma... » read more

RF And Microwave Solid-State Power Amplifiers Design Is A Speciality
By Wolfspeed, a Cree Company - 17 Jun, 2020 - Comments: 1

In the world of RF and microwave engineering, the design and development of solid-state amplifiers is a specialty. It has always required many years of specialized engineering experience and a suitable collection of test and measurement equipment. While these will always be necessary, to be successful in the marketplace today, it is also essential to use a combination of specialized and general... » read more

Manufacturing Bits: June 16
By Mark LaPedus - 16 Jun, 2020 - Comments: 0

GaN power modules Gallium-nitride (GaN) devices are emerging in several markets, such as power semiconductors and RF. GaN, a binary III-V compound, is a wide-bandgap technology, meaning it is faster and more efficient than silicon-based devices. GaN has 10 times the breakdown field strength with double the electron mobility than silicon. Generally, some GaN vendors don’t use a traditio... » read more

Full-Duplex Wireless Remains A Promise And A Challenge
By Bryon Moyer - 27 Apr, 2020 - Comments: 0

Wireless bandwidth capacity could double if we could use full-duplex communication. Unfortunately, that’s not as easy as it sounds. People are working hard on it, but we’re mostly not there yet. Full duplex seems easy. In fact, so easy that it was possible with the first basic telephones. There was one loop between each phone and the central office, and that one loop carried conversation... » read more
