Although the ubiquitous LM386 IC was designed to be used as an audio amplifier, it has a number of undocumented characteristics that can be exploited to create simple radio receiver circuits that ...

This application note presents the frequency receiver design notes of the TH71101, TH71102, TH71111 and TH71112. It discusses crystal selection of the receiver, the LNA (RF amplifier) considerations, ...

Close your eyes, listen to the music and feel the impact of the newly introduced Pioneer Elite audio/video receivers. With more than sixty-five years experience manufacturing audio products, Pioneer ...

[QRP Gaijin] likes to build regenerative receivers. If you’ve ever built a serious one, you know there are (at least) two problems: One is you need a variable capacitor (hard to find these days). The ...

If you’ve ever built a crystal radio, there’s something magical about being able to pull voices and music from far away out of thin air. If you haven’t built one, maybe you should while there’s still ...

Researchers designed a tiny receiver chip that is more resilient to interference, which could enable smaller 5G “internet of things” devices with longer battery lives MIT researchers have designed a ...
