The following is excerpted from Chapter 8 of “RF Circuit Design, 2e” by Christopher Bowick. Moving up the scale in complexity, we come to the next evolutionary RF architecture: the ...

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 ...

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 ...

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 ...

Weybridge, UK — Analog Devices has introduced a series of highly integrated RFICs (radio frequency integrated circuits) designed for LTE (long term evolution) and 4th generation (4G) cellular base ...

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 ...

In high-speed wireless communications systems, signals must be translated in frequency by up-conversion or down-conversion for signal propagation and processing. Traditionally known as mixing, this ...

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 ...
