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 is ...

A professor, a postdoctoral researcher and a graduate student hop onto a trampoline. No, it's not the opening line of a joke. It's a setup for the explanation of new Cornell-led research involving the ...

Pasternack's new waveguide mixers, also referred to as waveguide converters, are a key building block component of mm-wave receivers used to down-convert very high frequency signals to usable RF ...

Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard ...

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 ...

IRVINE, CALIF.—The new millimeter wave waveguide frequency mixers from Pasternack are available in six-down and six-up conversion models that cover the full Ka, Q, U, V, E and W bands. The mixers ...

Amateur radio is the only hobby that offers its licensed operators the chance to legally design, build, and operate high power radio transceivers connected to unlimited antenna arrays for the purpose ...

Bangalore: Analog Devices (ADI), a provider of semiconductors for signal processing applications introducted its two new high-performance RF (radio frequency) passive mixers. These can be used for a ...

NORWOOD, Mass.--(BUSINESS WIRE)--Analog Devices, Inc. (ADI), a world leader in semiconductors for signal processing applications, today announced the introduction of two new high-performance RF (radio ...

Why electrical circuits operating at optical frequencies is an attractive opportunity. How a new plasmonic arrangement is used to mix electrical signals at optical frequencies. The advantages and ...

Graphene circuit: This integrates a graphene transistor (inside the red box) with two other elements, called inductors, on a single chip. The black devices at the sides and top of the image are ...
