Abstract: This article describes the recent advances in very high-power transistors and amplifiers for applications above 1MHz. It focuses primarily on GaN-on-SiC HEMT devices for pulsed applications.

An anti-log amplifier design with a temperature-compensation network built around a nearly linear PTC thermistor.

Digital electronics rely on logic gates to perform operations. While modern integrated circuits (ICs) contain millions or billions of transistors packed into a small chip, understanding the ...

I own a pair of Sennheiser HD650 headphones. Mine are an early pair, bought around 20 years ago. They don’t see much use these days since What Hi-Fi? tests so many headphones, and there is always ...

The Samsung S90F is one of a recent wave of 48-inch OLED TVs to pass through our viewing rooms. And while, like all the ...

Magnetic resonance imaging (MRI) is one of the most commonly used tests in neurology and neurosurgery. MRI provides exquisite detail of brain, spinal cord and vascular anatomy, and has the advantage ...

Mike Zaite explains how a background in electronics and a front-row seat to the British Invasion of the 1960s led to the formation of Dr Z Amplification – and why the sonics always lead the schematics ...

Head to any step aerobics class and you may feel like the instructor is speaking another language. Don’t worry, we’ve all been there. But the good news is that most of the basic aerobic dance steps ...

Basic Military Pay or "base pay" is the standard amount of compensation for service members based on each individual pay grade. This is a service members compensation before additional allowances such ...
