In a superheterodyne radio, a local oscillator is an electronic circuit that generates a frequency based on the desired channel. The output of the oscillator is the channel frequency typically added ...

The ADL5812 uses revolutionary new broadband, square wave limiting, local oscillator (LO) amplifiers to achieve an unprecedented radio frequency (RF) bandwidth of 700 MHz to 2800 MHz. Unlike ...

Side-stepping traditional laser local oscillator down-conversion techniques, Australian engineers are using acoustic interactions to retrieve frequency and phase information from Gbit/s modulated ...

The master timing control circuit for most electronic applications is a precision signal source. For digital applications, it’s an accurate clock. In RF applications, it’s a carrier source for a ...

Parametric oscillators are a type of driven harmonic oscillator that are based on a nonlinear process in a resonant cavity, which are widely used in various areas of physics. In the past, parametric ...

Digital receivers have revolutionized electronic systems for a variety of applications including communications, data acquisition, and signal processing. This series shows how digital receivers, the ...

Experimentalists seeking to improve the coherent lifetimes of quantum bits have generally focused on mitigating decoherence mechanisms through, for example, improvements to qubit designs and materials ...

Modern radio receivers have a distinct advantage over the common early designs which I covered in my previous article. Most of the receivers you will have worked with over the past couple decades are ...

A word of advice: If you see an old direct satellite TV dish put out to the curb, grab it before the trash collector does. Like microwave ovens, satellite dishes are an e-waste wonderland, and just ...
