Frequency mixer symbol. In electronics, a mixer, or frequency mixer, is an electrical circuit that creates new frequencies from two signals applied to it.In its most common application, two signals are applied to a mixer, and it produces new signals at the sum and difference of the original frequencies.
As a mixer, its balanced operation cancels out many unwanted mixing products, resulting in a "cleaner" output. It is a generalized case of an early circuit first used by Howard Jones in 1963, [ 2 ] invented independently and greatly augmented by Barrie Gilbert in 1967. [ 3 ]
Mixed-signal ICs process both analog and digital signals together. For example, an analog-to-digital converter (ADC) is a typical mixed-signal circuit. Mixed-signal ICs are often used to convert analog signals to digital signals so that digital devices can process them.
The free design tool is the software accompaniment to ADI's complete portfolio of RF-to-digital functional blocks, allowing engineers to model RF signal chains using devices from across ADI's RF ...
Analog Devices , Inc. (ADI), also ... mixer. [36] At Analog Devices, Gilbert started the company's Northwest Labs design center in Oregon and continued to work on RF ...
Additive mixers are also known as analog adders to distinguish from the related digital adder circuits. Simple additive mixers use Kirchhoff's circuit laws to add the currents of two or more signals together, and this terminology ("mixer") is only used in the realm of audio electronics where audio mixers are used to add together audio signals ...
An RF chain is a cascade of electronic components and sub-units which may include amplifiers, filters, mixers, attenuators and detectors. [1] It can take many forms, for example, as a wide-band receiver-detector for electronic warfare (EW) applications, as a tunable narrow-band receiver for communications purposes, as a repeater in signal distribution systems, or as an amplifier and up ...
Passive intermodulation (PIM), however, occurs in passive devices (which may include cables, antennas etc.) that are subjected to two or more high power tones. [4] The PIM product is the result of the two (or more) high power tones mixing at device nonlinearities such as junctions of dissimilar metals or metal-oxide junctions, such as loose ...
