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 ...

A very simple DIY crystal oscillator circuit which use a quartz for frequency stability and a good rf transistor. Use a 2-nd or 3-rd harmonic crystal, for example if you want 100MHz use a 50MHz or ...

If you've ever designed an RF oscillator, you've probably encountered squegging. Sometimes called "motor boating," squegging causes oscillators to start and stop at frequencies much lower than the ...

While vacuum electronic devices have largely been superseded over much of consumer electronics, there’s one place where they can still be found for now. The cavity magnetron is a power RF oscillator ...

A new single-chip Bluetooth LSI, designated the TC35654, integrates both RF and baseband circuits The chip employs a 0.18 µm CMOS process technology for the RF circuit instead of the usual bipolar ...

Imperial College is developing an implantable passive blood pressure monitor based around a SAW (surface acoustic wave) oscillator. “In essence, it is an oscillator that you can ping from the outside ...
