Amplifying

Amplifiers were the original electronic devices, and still provide the most extensive range of products we offer. Amplifiers can provide DC precision in the nanovolt region, and can also provide low-noise signal gain in the multi-GHz region. Amplifiers can be very versatile operational amplifiers that can be set up for a wide range of functions, or very special purpose devices such as RF log/detector amplifiers. Variable gain amplifiers work from ultrasound to radar to provide high performance over a wide dynamic range.
