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 ...

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 ...

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 ...

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 ...

CML Microcircuits has expanded its SµRF product portfolio with the introduction of two high efficiency single- and two-stage power amplifiers for dual-cell lithium battery-powered wireless devices.

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 ...

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.

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

When building a radio transmitter, unless it’s a very small one indeed, there’s a need for an amplifier before the antenna. This is usually referred to as the power amplifier, or PA.
