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

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

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

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 ...

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.

The AMP 20 is configured as a cool-running 12-channel power amplifier with 200 watts per channel (8 ohms, 1kHz, THD 0.05 % with two channels driven), which is sufficient to drive multiple different ...

We recently saw how certain audio power amplifiers can be used as oscillators. This Design Idea shows how those same parts can be used for simple amplitude modulation, which is trickier than it might ...
