Uniquely configured PA + SPDT integration delivers ultra-fast switching, reduced footprint and lower total system cost for ...

Envelope tracking (ET) power amplifiers and supply modulators represent a pivotal advance in modern radio frequency (RF) design, particularly for wireless communications. These systems dynamically ...

Editor’s Note: This DI is a two-part series. In Part 1, Nick Cornford deliberately oscillates the TDA7052A audio power amplifier to produce a siren-like sound and, given the device’s distortion ...

Envelope tracking technology optimises the efficiency of radio frequency (RF) power amplifiers by dynamically adjusting the supply voltage in accordance with the amplitude envelope of the input signal ...

Anthem's new MCA 225/325/525 multi-ch amplifiers boast up to 600 watts/ch power and low noise starting at $2k but are there caveats? Read on to find out. MCA 525 GEN2 Power Amplifier 5-channel power ...

Cambridge Audio — the British audio manufacturer best known for its beautiful, high-end and new-age streamers, amplifiers and turntables — has announced a compact power amplifier for traditional hi-fi ...

Low-power optical device achieves around 100 times amplification using just a couple of hundred milliwatts of input power ...

Over the years, tutorials have appeared in EMC journals explaining how to estimate the power required from a power amplifier intended for use in an RF immunity test system. Little material, if any, ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

When building a radio transmitter, unless it’s a very small one indeed, there’s a need for an amplifier before the antenna.
