RF And Microwave Solid-State Power Amplifiers Design Is A Speciality


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


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


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

The Ins And Outs Of Silicon Carbide


John Palmour, CTO at Cree, sat down with Semiconductor Engineering to talk about silicon carbide, how it compares to silicon, what's different from a design and packaging standpoint, and where it's being used. What follows are excerpts of that conversation. SE: SiC is well-understood in power electronics and RF, but is the main advantage the ability to run devices hotter than silicon, or is ... » read more

Improving Wafer-Level S-Parameters Measurement Accuracy And Stability With Probe-Tip Power Calibration Up To 110 GHz For 5G Applications


Author: Choon Beng Sia, FormFactor Inc., Singapore Demands for mission critical wireless services such as autonomous driving and telehealth require higher data transfer rates and lower latencies. Such applications are now driving the use of radio frequencies (RF) at 28, 38, 60 and 73 GHz for the emerging 5G mobile communication systems. Waferlevel RF measurements of devices or circuits for 5... » read more

Parasitic Extraction of MIM/MOM Capacitors In Analog/RF Designs


The extensive use of MIM/MOM capacitors in analog/RF designs presents designers with extraction challenges that typically require multiple extraction techniques. The Calibre xACT platform offers analog/RF designers the fast performance of a rule-based extraction engine, and the capacity and performance of a field solver, to efficiently extract all parasitic components in a timely manner, with t... » read more

MOCVD Vendors Eye New Apps


Several equipment makers are developing or ramping up new metalorganic chemical vapor deposition (MOCVD) systems in the market, hoping to capture the next wave of growth applications in the arena. Competition is fierce among the various MOCVD equipment suppliers in the market, namely Aixtron, AMEC and Veeco. In addition, MOCVD equipment suppliers are looking for renewed growth in 2020, but b... » read more

Interconnect Inductance Extraction For Analog And RF IC Designs


Increasing operating frequencies for analog/RF designs mean interconnect inductance parasitic extraction is now required to ensure accurate circuit performance and high reliability. Automated field solver-based inductance extraction of both self and mutual parasitics enables IC companies to deliver analog/RF chips that provide the intended level of performance and reliability. To read more, ... » read more

Week In Review: Manufacturing, Test


Market research What are the hot chip markets for 2020? IC Insights released its rankings of sales growth rates for each of the 33 IC product categories defined by the World Semiconductor Trade Statistics (WSTS) organization. “After posting the two worst growth rates among all IC product categories in 2019, NAND flash and DRAM are forecast to be among the top three fastest-growing IC segment... » read more

Analog: Avoid Or Embrace?


We live in an analog world, but digital processing has proven quicker, cheaper and easier. Moving digital data around is only possible while the physics of wires can be safely abstracted away enough to provide reliable communications. As soon as a signal passes off-chip, the analog domain reasserts control for modern systems. Each of those transitions requires a data converter. The usage ... » read more
