Frequency mixers are crucial components in electronic devices, operating at billions (GHz, gigahertz) to trillions (THz, terahertz) of times per second.

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) input. When the LO ...

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.

Frequency mixers can be based on a number of different nonlinear semiconductor devices, including diodes and field-effect transistors (FETs). Because of their simplicity and capability of operation ...

The MIT team developed an electronic frequency mixer for signal detection that operates beyond 0.350 PHz using tiny nanoantennas. These nanoantennas can mix different frequencies of light, ...

Image reject mixers provide an integrated phase-canceling capability by removing the unwanted image signal from the output. This type of mixer reduces the number and complexity of the filters required ...

“The frequency mixer is one of the basic building blocks of analog electronics, and wireless communications in particular,” says IBM researcher Yu-Ming Lin. These devices are used in cell phones to ...

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

Now, researchers have put together a simple graphene-based test device that can operate at over 1.2GHz, and they used it as the basis for an all-graphene frequency mixer.

Mixers are fundamental components of many electronic communication systems. Frequency mixing up to 10 GHz and excellent thermal stability up to 125°C has been demonstrated with the graphene ...
