Frequency mixers are often implemented using a diode bridge or a Gilbert cell. Both types of mixers use a local oscillator (LO) to flip the polarity of the radio-frequency (RF ...

Imagine a frequency mixer that operates at a quadrillion (PHz, petahertz) times per second, enabling transmission and processing of significantly larger amounts of information at much higher speeds.

Frequency mixers are vital components in many electronic devices and typically operate using frequencies that oscillate billions (GHz, gigahertz) to trillions (THz, terahertz) of times per second.

The desired frequency converted signals are available at the IF port; the filter eliminates the unwanted high-frequency signal components generated by the mixing process. The LO drive level can be ...

Petahertz-frequency mixers would allow for shifting of signals up to optical frequencies and then back down to more conventional electronic frequencies.

Then, the AM radio is tuned just slightly off the right frequency and the FM signal is slope detected. The downconverter consists of a local tuned oscillator and a mixer.

SSB Receivers Rather than demodulating the radio signal with an envelope detector a SSB receiver down-converts the IF one more time using a second frequency mixer to the audio frequency range ...

Previously, researchers built graphene-based frequency mixers (an analog processor), but these needed to be driven by an external oscillator.

The frequency mixers widely used in radio observation equipment are superconductor-insulator-superconductor mixers (SIS mixers), which have the function of amplifying signals.

Concrete Mixers How to Select and Maintain the Right Mixer for Your Rental Fleet Mixers are staples for most rental fleets, but are often misunderstood by customers and counter staff alike.
