Researchers have devised a new concept of superconducting microwave low-noise amplifiers for use in radio wave detectors for radio astronomy observations, and they have successfully demonstrated a ...

Does the Mercury/Solis pairing tick all the boxes?

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 ...

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.

Doherty power amplifiers (DPAs) have emerged as a critical technology for modern wireless communication systems, notably in the context of 5G and beyond. These amplifiers utilise a dual-amplifier ...

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, ...

The PowerZone Connect 122, 252, 254, and 504 smart amplifiers offer ultra-compact, half rack, 1RU form factors, and more. When you purchase through links on our site, we may earn an affiliate ...

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.

Feedback is an ubiquitous and unavoidable basic technique that keeps the world running. It is only controversial in consumer audio, and then only specifically in power amplifiers. This dates from ...
