In a world of tight timelines and ever-increasing performance requirements, it’s critical to create circuit designs right the first time; thus, engineers in the analog and mixed-signal industry often ...

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.

Previous installments of this article series discussed the need to verify SPICE model accuracy and how to measure the output impedance, small-signal bandwidth, and input-referred errors of operational ...

At a 25-dBm input, the third order output power is about 12.5 dBm compared to 45 dBm for the linear output. But, for a 10-dB increase at the input, it’s grown to 42.5 dBm while the linear output has ...

Evaluating S-parameters and other CW stimulus responses is essential for characterising rf amplifiers. An rf vector network analyser (VNA) plays a critical role for this purpose, and proper ...

The FFT from the amplifier output is nice and clean with 2 nd harmonic down -109dB below the fundamental when driven with 2Vrms on the analog inputs. Curious when the same test was repeated with a ...

Howdy guys - I have an XPA-2 amp hooked up to a pair of B&W683's and am curious how many watts (in real time) I am using. I am not worried about over driving the speakers or worried that the amp is ...

The Starke Sound Fiera4 is an exciting new four channel Class D amplifier. It provides plenty of power (130wpcx4) to juice your home theater in a light weight and energy efficient package. Read on.

I'm researching preamp-amp matches and due to lack of information on the Internet am left with a question regarding output/input differences between balanced and unbalanced feeds. The contemplated ...

You are not going to be able to buy any modern hi-fi stereo power amplifier for anything even close to what Adcom is asking for the GFA-585se. Its high power output, incredible sound a low noise belie ...
