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 ...

Abstract: The valuable performance figures of micro-electromechanical systems (MEMS) offer many improvements in the field of radio-frequency (RF) circuits for mobile communications compared to ...

Sensors monitoring mechanical and biological systems must often scavenge power from the thing being sensed. The oscillator circuits shown here let you operate those sensors. Sensor circuits that ...

While vacuum electronic devices have largely been superseded over much of consumer electronics, there’s one place where they can still be found for now.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 ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a ...

The integration and miniaturization of amplifiers and oscillators, crucial for modern electronics, are achieved through integrated circuits, allowing for smaller, more reliable, and efficient devices.

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 ...

An RF oscillator is an electronic circuit that generates radio frequency signals, making it essential for various applications including communication systems, signal processing, and broadcasting.

The new Plessey PL.14 Tuners feature a specially developed RF/ oscillator unit for high gain, low noise and low drift, incorporating the latest frame grid valves to ensure optimum performance. So, 57 ...
